How to Choose the Best Internet Security Provider

Choosing the best internet security provider is about more than picking the biggest name. The right option should protect the devices you use, suit the way you go online and offer support you can rely on. Features, prices and performance vary, so it is worth comparing what each provider includes before you subscribe.

What does an internet security provider do?

Internet security providers offer software and services designed to reduce online risks. Depending on the package, these may include protection against viruses, ransomware, phishing and harmful websites. Some providers also offer a firewall, parental controls, password management, identity monitoring or a virtual private network (VPN).

Security software can help spot and block threats, but it cannot prevent every risk. Keeping your devices and apps up to date, using unique passwords and being cautious with unexpected links remain important.

What to look for

  • Strong malware protection: Look for independent test results that assess how well the product detects and blocks threats.
  • Coverage for your devices: Check whether the subscription supports Windows, macOS, Android or iOS, and how many devices you can protect.
  • Useful features: Choose features that match your needs. A family may value parental controls, while someone who often uses public Wi-Fi may want a VPN.
  • Ease of use: Clear alerts and straightforward settings make it easier to manage your protection.
  • Performance: Security software should protect your devices without noticeably slowing them down.
  • Price and renewal terms: Compare the introductory price with the renewal cost. Check what is included and how cancellation works.
  • Customer support: Find out how to contact support and whether help is available when you need it.
  • Privacy practices: Read the provider’s privacy information to understand what data it collects and how it is used.

Providers worth comparing

Several established brands offer consumer security products. The best fit depends on your devices, budget and the features you actually need.

Bitdefender

Bitdefender offers security packages for individuals and families, with options that can include malware protection, web security and additional privacy tools. Compare the features in each plan, as the entry-level package may differ from higher tiers.

Norton

Norton provides a range of security subscriptions, some of which bundle features such as a VPN, password management or identity-related services. Check which features are available in the UK and whether they are included in the plan you are considering.

ESET

ESET is another provider to consider, particularly if you want a security product with configurable settings. Compare its device support and package features with your requirements before choosing.

Trend Micro

Trend Micro offers protection focused on areas such as malware and online threats. As with any provider, check independent test results and make sure the plan covers the operating systems and devices you use.

Malwarebytes

Malwarebytes offers products for detecting and blocking malicious software and other online threats. Review the current package details to see which protections are included and whether they meet your needs as a primary security solution.

These examples are not a definitive ranking. Products change over time, and independent testing can vary by test date, device and threat type. Check recent results from reputable testing organisations before making a decision.

Free security software or a paid subscription?

Free security tools may provide a useful baseline, while paid plans often add features such as protection for multiple devices, parental controls or a VPN. However, a longer feature list does not automatically make a product better. Consider whether you will use the extras and whether they are already available through your operating system, browser or another service.

Be cautious of unsolicited pop-ups claiming that your device is infected or urging you to call a support number. Use the provider’s official website or app to check your subscription and contact support.

How to make the final choice

  1. List the devices and operating systems you need to protect.
  2. Decide which features matter to you, such as parental controls or a VPN.
  3. Compare recent independent test results and product reviews.
  4. Check the full price, renewal terms and cancellation process.
  5. Download software only from the provider’s official website or an authorised app store.

So, which internet security provider is best?

There is no single provider that is best for everyone. A good choice is one that offers dependable protection for your devices, includes features you will use, is easy to manage and has clear pricing and privacy terms. Compare current plans and recent independent test results rather than choosing on brand name alone.

 

Top 5 Tips for Choosing the Best Internet Security Provider

  1. Choose a provider with strong, independently tested protection.
  2. Check that updates and customer support are reliable.
  3. Look for clear privacy policies and minimal data collection.
  4. Compare prices, renewal costs and device limits.
  5. Pick a plan with features suited to your devices and needs.

Choose a provider with strong, independently tested protection.

Choose an internet security provider with strong protection that has been independently tested by reputable organisations. These tests assess how effectively a product detects and blocks threats such as malware and phishing, giving you a clearer basis for comparison than marketing claims alone. Check recent results, as performance can change over time, and make sure the product supports your devices and operating systems.

Check that updates and customer support are reliable.

When choosing an internet security provider, check that its software receives regular, timely updates to respond to new threats and keep protection effective. Reliable customer support is equally important: look for clear contact options, helpful guidance and support hours that suit your needs. Recent user reviews can offer useful insight into how quickly the provider resolves problems.

Look for clear privacy policies and minimal data collection.

When choosing an internet security provider, look for a clear privacy policy that explains what information is collected, why it is needed and how long it is kept. A provider that collects only the data required to deliver its service can help limit unnecessary exposure of your personal information. Check whether data is shared with third parties, and look for straightforward options to manage or delete your information.

Compare prices, renewal costs and device limits.

Before choosing an internet security provider, compare more than the introductory price. Check the renewal cost, as a discounted first year may be followed by a higher subscription fee, and make sure you understand how to cancel or change your plan. Also review the device limit: a cheaper package may cover only one or two devices, while a household may need protection for several computers, phones and tablets. Comparing the total cost against the number of devices covered can help you find a plan that offers good value.

Pick a plan with features suited to your devices and needs.

Choose an internet security plan that matches the devices you use and the risks you want to manage. Check that it supports your operating systems and covers enough devices, then consider which extras are genuinely useful—such as parental controls for a family, a VPN for using public Wi-Fi or identity monitoring for added reassurance. There’s little benefit in paying for features you won’t use, so compare plans carefully and check what’s included in the price.

ISO 9001 Compliance Software: A Practical Guide

Maintaining an effective quality management system (QMS) takes more than writing procedures and preparing for an audit. Organisations need to manage documents, monitor processes, record issues and show that they are continually improving. ISO 9001 compliance software can bring these activities together, making it easier to manage a QMS and keep useful evidence in one place.

Software does not guarantee ISO 9001 certification. Certification depends on how an organisation’s QMS works in practice and on an assessment by an independent certification body. The right system can, however, help teams organise their work and maintain processes that support the requirements of the standard.

What is ISO 9001 compliance software?

ISO 9001 compliance software is a digital platform used to manage some or all of the processes involved in operating a QMS. Depending on the product, it may support document control, staff training records, audits, corrective actions, risk management, supplier reviews and performance reporting.

Some platforms are designed specifically for quality management. Others are broader governance, risk and compliance systems that can be configured to support ISO 9001 alongside other standards or regulatory requirements.

How software can support an ISO 9001 QMS

ISO 9001 sets out requirements for a QMS, including how an organisation controls its processes, meets customer requirements, evaluates performance and pursues improvement. Software can help make these activities more consistent and traceable.

Document and record control

Teams need to know which procedures, forms and work instructions are current. Document control features can manage approval workflows, revision histories, access permissions and review dates. This helps reduce the risk of staff using an outdated document and makes it easier to locate relevant records.

Audit planning and findings

Audit tools can help schedule internal audits, assign auditors, record evidence and track findings through to closure. A central audit history can also help managers identify recurring issues or areas that may need closer attention.

Nonconformities and corrective actions

When a process does not meet a requirement, the organisation needs to respond appropriately and consider why it happened. Software can record nonconformities, allocate actions, set due dates and document follow-up checks. This supports a more structured approach than relying on separate spreadsheets or email chains.

Risk and opportunity management

A QMS should reflect the organisation’s context and the risks and opportunities that could affect its intended results. Depending on the platform, users may be able to record assessments, assign owners, review controls and monitor changes over time. The assessment itself still requires informed judgement from people who understand the business.

Training and competence records

Organisations need to determine the competence required for relevant roles and retain appropriate evidence. Software can link training requirements to job roles, record completed learning and flag upcoming renewals or gaps. It may also help managers see whether people have acknowledged changes to procedures.

Supplier and customer feedback

Some systems help manage supplier evaluations, customer feedback, complaints and service issues. Bringing these records together can make it easier to spot patterns and consider whether action is needed.

Performance monitoring and reporting

Dashboards and reports can summarise information such as audit status, overdue actions, complaints or process performance. Useful reporting depends on accurate data and meaningful measures; a dashboard alone does not demonstrate that quality objectives are being achieved.

Benefits of using ISO 9001 software

  • Greater visibility: Teams can see the status of audits, actions, documents and reviews.
  • More consistent processes: Standard workflows can help staff follow agreed steps across departments or sites.
  • Improved traceability: Revision histories and action records can provide a clearer account of decisions and changes.
  • Less administrative effort: Notifications, templates and automated workflows may reduce repetitive manual tasks.
  • Better access to information: Staff can find relevant records more easily, subject to appropriate access controls.
  • Support for continual improvement: A joined-up view of issues, causes and actions can help teams learn from experience.

The benefits depend on the way the software is selected, configured and used. A system that is difficult to maintain or does not fit existing processes can add work rather than reduce it.

Choosing the right software

Before comparing products, map out how the organisation currently manages its QMS and identify the problems it wants to solve. Consider the following questions:

  • Which QMS activities need the most support?
  • Can the platform handle the organisation’s locations, teams and approval structures?
  • Is it straightforward for occasional users as well as quality professionals?
  • Can existing documents and records be migrated without losing important information?
  • Does the system provide clear permissions, audit trails and backup arrangements?
  • Can it integrate with tools already in use, such as identity management or document platforms?
  • What support, training and implementation assistance are included?
  • How are data security, hosting, retention and export handled?
  • Can the system support other standards or business needs if requirements change?

Ask suppliers to demonstrate realistic tasks using examples relevant to the organisation. A polished dashboard is less important than whether staff can complete everyday activities accurately and efficiently.

Implementation: technology and people

Successful implementation starts with clear ownership. Senior leaders should support the QMS, while process owners and staff should help shape workflows that reflect how work is actually done. Simply transferring poorly understood procedures into a new platform will not improve them.

A practical implementation may include reviewing existing documents, agreeing responsibilities, configuring approval routes, migrating records, training users and testing the system before wider use. It is also important to establish how the organisation will review software access, maintain records and manage changes to its QMS.

Keep the system proportionate. Not every process needs a complex workflow, and excessive forms or approvals can make the QMS harder to use. The aim is to provide enough control and evidence to support effective operations without creating unnecessary bureaucracy.

Software and ISO 9001 certification

ISO 9001 compliance software can help an organisation prepare for audits by making records easier to manage and retrieve. It cannot replace the work required to understand customer needs, control processes, develop competent staff, assess risks or act on performance information.

Certification is granted by an independent certification body following an assessment. Organisations should check which edition of ISO 9001 applies to their certification programme and confirm any transition arrangements with their certification body. Software vendors can explain how their products support a QMS, but their claims should be assessed against the organisation’s own requirements.

Common pitfalls to avoid

  • Buying before defining needs: A long feature list does not necessarily mean a product is a good fit.
  • Treating software as a substitute for a QMS: The platform supports the system; it does not create effective processes by itself.
  • Overcomplicating workflows: Too many steps can discourage use and delay action.
  • Ignoring user adoption: Staff need appropriate training and a clear understanding of why records matter.
  • Failing to review data: Records are valuable only when they are accurate, relevant and used to inform decisions.
  • Assuming certification is guaranteed: No software product can promise a successful certification outcome.

Conclusion

ISO 9001 compliance software can make quality management more organised, visible and traceable. It may be particularly useful for organisations managing multiple sites, large document sets, frequent audits or numerous corrective actions. The best choice is one that fits the organisation’s processes, is usable by its staff and supports continual improvement without adding unnecessary complexity.

When selected and implemented carefully, software can provide a practical foundation for managing a QMS. The lasting results still depend on committed leadership, engaged employees and a genuine focus on delivering consistent quality to customers.

What is the best compliance software?

There is no single “best” compliance software for every organisation. The right choice depends on your size, industry, existing processes and the standards you need to manage. For ISO 9001, look for a system that makes document control, audits, corrective actions, training records and reporting straightforward, with suitable access controls and a clear audit trail. Consider ease of use, implementation support, integrations and total cost, and ask suppliers to demonstrate how the software handles your real-world workflows. Ultimately, the best option is one your team will use consistently and that supports an effective quality management system—not a guarantee of certification.

How much does ISO 9001 cost?

The cost of ISO 9001 varies depending on your organisation’s size, complexity, number of sites and current quality management processes. Expenses may include consultancy, staff training, implementing or improving your quality management system, software subscriptions and certification audits. ISO 9001 compliance software pricing also differs by provider and may be based on users, features or locations. Request itemised quotes and check for implementation, support and renewal fees so you can estimate the total cost for your organisation.

What is ISO 9001 compliance?

ISO 9001 compliance means operating a quality management system (QMS) that meets the requirements of the ISO 9001 standard. It involves establishing and maintaining processes to deliver products or services consistently, meet customer and applicable regulatory requirements, monitor performance and drive continual improvement. Compliance is not achieved simply by using particular software: the organisation must put its QMS into practice and keep appropriate evidence. ISO 9001 certification is a separate step, assessed by an independent certification body.

What is the best QMS software?

The best QMS software is the system that fits your organisation’s size, processes and quality objectives—not necessarily the one with the most features. Look for a platform that is easy for staff to use and supports the activities you need, such as document control, audits, corrective actions, training records and reporting. Check its security, integrations, implementation support and ability to grow with your organisation, and ask suppliers to demonstrate real-world tasks before you decide. QMS software can help manage an ISO 9001 system, but it cannot guarantee certification or replace effective processes and staff involvement.

What is ISO 9001 software?

ISO 9001 software is a digital tool that helps an organisation manage the processes and records involved in its quality management system (QMS). Depending on the platform, it may support document control, staff training records, internal audits, risk assessments, customer feedback and corrective actions. It can make QMS information easier to organise, review and track, but the software itself does not guarantee ISO 9001 compliance or certification; the organisation must put effective processes into practice and demonstrate that they meet the standard’s requirements.

What is the best software for ISO certification?

The best software for ISO certification is the platform that fits your organisation’s processes, size and budget, rather than simply offering the longest list of features. Look for tools that support document control, audits, nonconformities, corrective actions, risk management and staff training, with clear reporting and appropriate access controls. Before choosing, ask suppliers to demonstrate everyday tasks using your own examples and check that the system is straightforward for staff to use. ISO software can help you manage evidence and maintain your quality management system, but it cannot guarantee certification; that depends on how effectively the system is implemented and assessed by an independent certification body.

How do you ensure compliance to ISO 9001?

To ensure compliance with ISO 9001, establish and maintain a quality management system that meets the standard’s requirements and reflects how your organisation operates. Define responsibilities and processes, keep controlled records, train employees, monitor performance and customer feedback, and address risks and opportunities. Regular internal audits and management reviews help identify gaps, while corrective actions and follow-up checks support continual improvement. ISO 9001 compliance software can help organise documents, audits, actions and evidence, but it cannot guarantee compliance on its own; the system must be used effectively, and certification requires assessment by an independent certification body.

Network Security Solution Companies: What They Do and How to Choose One

Organisations rely on connected systems to communicate, store information and deliver services. That connectivity also creates opportunities for cyber criminals, making network security an essential part of business operations. Network security solution companies help organisations protect their networks, detect suspicious activity and respond to threats.

These providers range from specialist consultancies to managed security service providers and technology vendors. Understanding what they offer can help a business find the right support for its size, risks and technical requirements.

What do network security companies do?

Network security companies help protect the systems, devices and data that connect across an organisation. Depending on the provider, their work may include:

  • Security assessments: Reviewing network architecture, configurations and existing controls to identify weaknesses.
  • Firewalls and access controls: Helping manage which users, devices and applications can access particular resources.
  • Intrusion detection and prevention: Monitoring network traffic for patterns that may indicate an attack or policy breach.
  • Threat monitoring: Analysing security alerts and activity, often around the clock, to identify potential incidents.
  • Incident response: Supporting an organisation when a security incident occurs, including investigation, containment and recovery.
  • Cloud and remote-access security: Protecting cloud services and connections used by staff working away from the office.
  • Compliance support: Helping organisations assess security controls against relevant legal, regulatory or industry requirements.

Some companies provide advice and implementation services, while others supply security products or manage them on a customer’s behalf. A provider may offer one of these services or combine several.

Common types of provider

Security consultancies

Consultancies assess an organisation’s security and recommend improvements. They may carry out network reviews, penetration testing, risk assessments or security planning. This can suit organisations that need independent expertise or help defining a security strategy.

Managed security service providers

Managed security service providers (MSSPs) operate or monitor security tools for their customers. Services may include alert monitoring, firewall management and incident support. An MSSP can give an organisation access to specialist skills, although the precise service hours and response responsibilities should be checked carefully.

Security technology vendors

Vendors develop products such as firewalls, endpoint protection, network monitoring platforms and identity security tools. Buying technology is only one part of the process: organisations also need to configure it, keep it up to date and ensure that someone reviews the alerts it generates.

Systems integrators

Systems integrators connect security products and services with an organisation’s existing technology. They can help ensure that tools work together, but it is important to establish who will manage and support the systems after implementation.

How to choose a network security provider

The right provider will depend on an organisation’s existing systems, internal expertise, budget and exposure to risk. Before making a decision, consider the following factors:

  • Relevant experience: Look for experience with organisations of a similar size, sector and technical complexity.
  • Clearly defined services: Confirm exactly what is included, such as monitoring hours, reporting, maintenance and incident response.
  • Response arrangements: Ask how alerts are prioritised, who is contacted and how quickly the provider can act during an incident.
  • Visibility and reporting: The provider should explain what it monitors and provide reports that help the organisation understand its security position.
  • Compatibility: Check that proposed services work with existing networks, cloud platforms, identity systems and business applications.
  • Data handling: Understand what information the provider can access, where it is stored and how it is protected.
  • Service levels and accountability: Review contracts, service-level agreements, responsibilities and escalation processes.
  • Scalability: Consider whether the service can adapt as the organisation adds users, locations or cloud services.

Certifications and recognised security frameworks can provide useful evidence of a provider’s processes, but they should not replace due diligence. Ask for references, review the contract and make sure the provider can explain its approach in clear, practical terms.

Questions to ask before signing a contract

A structured conversation can reveal whether a provider’s offering matches the organisation’s needs. Useful questions include:

  • Which parts of our network and infrastructure will you monitor?
  • Is monitoring provided continuously, and what happens outside standard working hours?
  • Who investigates alerts and who is authorised to take action?
  • How will you work with our internal IT or security team?
  • What information will appear in reports, and how often will they be delivered?
  • How do you test your own processes and keep your staff’s skills current?
  • What are the arrangements for ending the service and transferring data or systems?

Building a stronger security approach

Working with a network security company can strengthen an organisation’s defences, but it does not remove the need for good internal practices. Businesses should maintain an accurate inventory of devices and systems, apply security updates, restrict access to what users need and prepare an incident response plan. Staff awareness and regular reviews of security controls also play an important role.

Ultimately, the best network security provider is one that understands the organisation’s risks, communicates clearly and delivers services that can be measured. Comparing providers on their expertise, responsibilities and response arrangements can help businesses make an informed choice and build a more resilient network.

Which network security is best?

There is no single network security solution that is best for every organisation. The right choice depends on factors such as the size of the business, its network, the data it handles and the threats it faces. Most organisations benefit from a layered approach combining measures such as firewalls, network monitoring, access controls, multi-factor authentication, regular updates and a tested incident response plan. A network security provider can assess your requirements and recommend solutions that fit your risks, existing systems and budget.

What are the 5 types of network security?

The five common types of network security are firewalls, which control incoming and outgoing traffic; access control, which limits network access to authorised users and devices; intrusion detection and prevention systems, which identify or block suspicious activity; antivirus and endpoint protection, which defend connected devices against malicious software; and virtual private networks (VPNs) and encryption, which help protect data as it travels across networks. These measures are often used together, as no single type can protect a network on its own.

ISO 27001 Risk Management Software: A Practical Guide

Managing information security risks is central to an effective Information Security Management System (ISMS). For many organisations, spreadsheets and email are enough to get started, but they can become difficult to maintain as risks, controls, owners and evidence multiply. ISO 27001 risk management software can bring this information together and help teams run a more consistent, visible and repeatable process.

Software does not make an organisation compliant or guarantee certification. It can, however, help people carry out and document the activities needed to manage information security risks in line with ISO/IEC 27001.

What is ISO 27001 risk management software?

ISO 27001 risk management software is a tool for recording, assessing, treating and reviewing information security risks. Depending on the product, it may also support wider ISMS activities, such as managing policies, controls, audits, corrective actions and compliance evidence.

A dedicated platform can provide a shared view of the risk management process. Teams can see which risks have been identified, how they have been assessed, who is responsible for them and what actions are still outstanding.

How risk management fits into ISO 27001

ISO/IEC 27001 requires organisations to establish and apply an information security risk assessment process. The method should be defined and consistent, so that assessments can produce comparable and repeatable results. Organisations also need criteria for accepting risks and for conducting assessments at planned intervals or when significant changes occur.

Risk treatment follows assessment. The organisation decides how to address each risk, selects appropriate controls and records its treatment decisions. The Statement of Applicability (SoA) documents the controls selected, their status and the justification for including or excluding them.

The standard does not prescribe one universal scoring model or require a particular software product. Each organisation must choose an approach suited to its context, obligations and risk appetite, then apply it consistently.

What features should you look for?

A configurable risk assessment method

Look for software that can reflect your organisation’s assessment criteria, such as likelihood and impact scales, risk levels and acceptance thresholds. The tool should support your chosen method rather than force you into a model that does not fit your business.

A central risk register

A well-structured risk register should let you record the risk, its source or scenario, affected assets or processes, existing safeguards, assessment results, owner and review date. It should also preserve a useful history of changes and decisions.

Risk treatment and action tracking

Once a risk has been assessed, the next steps need to be clear. Software can help assign treatment decisions, actions, owners and deadlines, then track progress through to completion. It should also make it easy to document why a risk is accepted, reduced, avoided or shared.

Links between risks, controls and the SoA

Connecting risks with controls and treatment plans makes it easier to understand why safeguards are in place and whether they are working as intended. Some platforms also help maintain the SoA and link it to supporting evidence. Check that the product supports the edition of the standard and control framework relevant to your ISMS.

Reviews, approvals and audit trails

Risk assessments should not be treated as one-off paperwork. Automated reminders can prompt owners to review risks, while approval workflows can help ensure that important decisions are reviewed by the right people. An audit trail can show when records were created or changed and who approved them.

Reporting and evidence management

Useful reports help management understand the organisation’s exposure, overdue actions and changes in risk over time. Evidence management can also make it easier to locate records during internal audits, management reviews and certification audits. Reports should be clear and relevant, not just detailed.

Benefits of using dedicated software

  • Improved visibility: A central view makes it easier to see priority risks, assigned owners and outstanding treatments.
  • More consistent assessments: Shared criteria and structured workflows can reduce variation between teams.
  • Clearer accountability: Named owners and due dates help turn risk decisions into practical actions.
  • Better traceability: Links between risks, controls, decisions and evidence make it easier to explain how the ISMS works.
  • Less manual administration: Reminders, workflows and reusable records can reduce repetitive work, particularly as the programme grows.

These benefits depend on good implementation. Poorly configured software can simply digitise an unclear process, so the risk methodology and responsibilities should be agreed before the tool is rolled out.

How to choose the right solution

Start by mapping your current process. Identify who assesses risks, who approves treatment plans, how often reviews happen and what information needs to be retained. This will help you distinguish essential features from optional extras.

When comparing products, consider:

  • Whether the assessment method and risk scales are configurable.
  • How easily users can record, review and update risks.
  • Whether the tool supports risk treatment, approvals and action tracking.
  • How risks connect to controls, the SoA, policies and evidence.
  • Whether reports can be tailored for operational teams and senior management.
  • Access controls, data security, data hosting and backup arrangements.
  • Integration with existing identity, ticketing, document management or business systems.
  • Implementation support, training, ongoing costs and the process for exporting your data.

Ask suppliers to demonstrate realistic scenarios using your organisation’s requirements. A clear and usable platform is often more valuable than a long list of features that staff will not adopt.

Common implementation mistakes

One common mistake is treating risk scores as objective facts. Scores are estimates based on defined criteria and available information; they should support informed decisions, not replace them. Another is assigning every risk to a security team without involving the people who understand the affected services and processes.

Organisations may also overcomplicate their scoring model, import a large volume of poorly defined risks or assume that buying software will resolve gaps in governance. A focused register, clear ownership and regular review are usually more effective than an elaborate system that is not maintained.

Making software part of an effective ISMS

ISO 27001 risk management software works best when it supports an established, organisation-wide process. Define the assessment method, agree risk acceptance criteria, assign responsibilities and set review triggers. Then configure the software around those decisions and provide practical training to the people who will use it.

Review whether the process is producing useful decisions: Are significant risks being identified? Are treatment actions completed? Are accepted risks properly authorised? Do changes to the organisation prompt reassessment where needed? These questions matter more than the number of records in a register.

Conclusion

ISO 27001 risk management software can help organisations maintain a clearer, more consistent and more auditable approach to information security risk. The right solution brings assessments, treatment plans, controls, owners and evidence into a manageable process, while supporting collaboration across the business.

Technology is only one part of the picture. Effective risk management still depends on a suitable methodology, informed judgement, accountable owners and regular review. Choose software that supports these fundamentals and fits the way your organisation works.

 

7 Essential Tips for Effective ISO 27001 Risk Management Software

  1. Choose software that maps risks to ISO 27001 controls.
  2. Keep a clear, current risk register.
  3. Assign owners and review dates to each risk.
  4. Record treatment decisions and approvals.
  5. Track actions, evidence and residual risk.
  6. Use role-based access and audit logs.
  7. Check reporting supports audits and management reviews.

Choose software that maps risks to ISO 27001 controls.

Choose ISO 27001 risk management software that lets you link each risk to the relevant controls and document why those controls have been selected. This creates a clear connection between identified risks, treatment decisions and the safeguards used to address them, making it easier to track coverage, maintain the Statement of Applicability and prepare evidence for reviews or audits. Ensure the software supports your organisation’s chosen risk assessment method, rather than assuming that a control mapping alone guarantees compliance.

Keep a clear, current risk register.

Keep a clear, current risk register by recording each information security risk in a consistent format, including its potential impact, likelihood, existing controls, assigned owner and agreed treatment actions. Review entries regularly and whenever significant changes occur, such as new systems, suppliers or business processes. A well-maintained register helps teams prioritise risks, track actions and provide reliable evidence for management reviews and audits.

Assign owners and review dates to each risk.

Assign an owner and review date to every risk in your ISO 27001 risk management software. A named owner is responsible for monitoring the risk, updating its assessment and progressing any agreed treatment actions, while a review date ensures it is reconsidered regularly. Set reviews at intervals that reflect the risk’s severity, and bring them forward when significant changes occur, such as a new system, supplier or threat. This helps keep the risk register accurate and ensures important risks do not go unnoticed.

Record treatment decisions and approvals.

Record each risk treatment decision in your ISO 27001 risk management software, including the chosen approach, the reasons behind it, the actions required, the responsible owner and the target completion date. Document formal approvals as well, particularly when a risk is accepted or residual risk remains. A clear, traceable record helps demonstrate accountability, supports consistent reviews and gives auditors evidence that decisions were considered and authorised.

Track actions, evidence and residual risk.

Track every risk treatment action from assignment through to completion, with a named owner, deadline and clear status. Keep supporting evidence—such as approvals, test results or updated procedures—linked to the relevant risk and control, so it is easy to verify progress during reviews and audits. Once actions are complete, reassess the risk to determine its residual level, record whether that level is acceptable and schedule a further review where needed. This creates a clear audit trail and helps ensure that treatment plans lead to measurable improvements.

Use role-based access and audit logs.

Use role-based access controls to ensure people can view or change only the risk records and settings needed for their responsibilities. This helps protect sensitive information and reduces the chance of accidental or unauthorised changes. Keep audit logs enabled so there is a clear record of who accessed or updated information, what changed and when. Regularly review permissions and logs to confirm that access remains appropriate and to support investigations and audits.

Check reporting supports audits and management reviews.

Check that the software can produce clear, up-to-date reports for both audits and management reviews. It should make it easy to show risk assessments, treatment decisions, control status, overdue actions and changes since the previous review, with links to supporting evidence where appropriate. Reports tailored to different audiences help auditors verify the process and enable senior management to make informed decisions about priorities, resources and risk acceptance.

Choosing a Network Security Services Company

Modern organisations rely on connected systems to communicate, store information and deliver services. As networks become more complex, they can also become harder to protect. A network security services company helps businesses identify risks, strengthen defences and respond to security incidents.

What does a network security services company do?

A network security services company provides expertise and tools to help protect an organisation’s digital infrastructure. Services may cover on-site systems, cloud environments, remote users and the devices that connect to a business network.

Depending on an organisation’s needs, services may include:

  • Security assessments: Reviewing network architecture, configurations and existing controls to identify weaknesses.
  • Continuous monitoring: Looking for unusual activity and potential threats across network systems.
  • Penetration testing: Testing systems in a controlled way to discover vulnerabilities before attackers do.
  • Firewall and access management: Configuring controls to limit network access to authorised users and devices.
  • Incident response: Helping investigate and contain security incidents, and supporting recovery.
  • Cloud security: Reviewing cloud services and configurations to reduce exposure to misconfiguration and unauthorised access.
  • Staff guidance: Helping employees recognise common risks, such as phishing and unsafe handling of sensitive information.

Why businesses use external security specialists

Maintaining effective network security takes time, specialist knowledge and regular attention. An external provider can offer access to experienced security professionals and services that may be difficult to maintain in-house. This can be especially useful for organisations with limited internal resources or complex IT environments.

External support can also bring an independent perspective. A specialist may spot gaps that are easy to overlook during day-to-day operations, such as excessive permissions, outdated systems or network connections that are no longer needed.

How to choose the right provider

The right provider should understand your organisation’s size, sector, technology and risk priorities. Before engaging a company, consider the following:

  • Scope: Confirm which systems and services are covered, and what is excluded.
  • Approach: Ask how assessments are carried out, how findings are prioritised and how often reviews take place.
  • Incident support: Establish what help is available during an incident, including response times and responsibilities.
  • Reporting: Look for clear, practical reports that explain risks and recommend actions in language your teams can use.
  • Experience: Check that the provider has relevant experience with your type of organisation and infrastructure.
  • Data handling: Understand how the provider accesses, stores and protects your information.
  • Service boundaries: Make sure responsibilities are clear between your team, the provider and any other suppliers.

Network security is an ongoing process

A single assessment cannot provide lasting protection. Networks change as organisations adopt new applications, onboard users, update equipment and move services to the cloud. Security controls should therefore be reviewed regularly, with identified issues tracked through to resolution.

Good network security combines technology with sound processes. This includes keeping systems updated, applying least-privilege access, maintaining reliable backups and preparing a response plan. Staff awareness also matters, as everyday actions can affect an organisation’s exposure to risk.

Build a security approach that fits your organisation

A network security services company can help an organisation understand its risks and make informed improvements. The best results come from a partnership built around clear objectives, regular communication and practical recommendations. By choosing a provider that fits your needs, you can strengthen your defences and support the secure, reliable operation of your business.

 

Essential Tips for Selecting a Network Security Services Provider

  1. Check the provider’s certifications and track record.
  2. Choose services tailored to your organisation’s risks.
  3. Ask how threats are monitored around the clock.
  4. Confirm incident response times and procedures.
  5. Ensure customer data is protected and handled lawfully.
  6. Review service levels, costs and contract terms.
  7. Request regular reports and security assessments.
  8. Test the provider’s incident response plan together.

Check the provider’s certifications and track record.

Check a network security services provider’s certifications and track record before engaging them. Relevant, current certifications can indicate that their team has recognised expertise, while case studies, references and client reviews can help show how they apply it in practice. Ask about experience with organisations and systems similar to yours, and look for clear evidence of dependable service and effective results.

Choose services tailored to your organisation’s risks.

Choose network security services that reflect your organisation’s specific risks, rather than paying for a one-size-fits-all package. Consider the data you hold, the systems you rely on, how staff and suppliers access your network, and any legal or regulatory requirements. A provider should take time to understand these factors and recommend proportionate support, whether that means regular security assessments, continuous monitoring, incident response planning or stronger access controls.

Ask how threats are monitored around the clock.

Ask how the provider monitors threats around the clock, including whether monitoring is handled by a dedicated security operations team or automated tools. Find out how alerts are investigated, how quickly your organisation will be notified and what support is available outside normal business hours. Clear answers help you understand whether potential incidents can be identified and escalated promptly, day or night.

Confirm incident response times and procedures.

Confirm the provider’s incident response times and procedures before signing an agreement. Find out how to report a suspected breach, who will handle it, and how quickly support will be available, including outside normal working hours. Clear escalation steps, communication arrangements and responsibilities can help your organisation act promptly and limit disruption when an incident occurs.

Ensure customer data is protected and handled lawfully.

A network security services company should protect customer data throughout its lifecycle and handle it in accordance with applicable data protection laws, including the UK GDPR and Data Protection Act 2018. This means using appropriate safeguards, limiting access to authorised personnel, explaining how data is collected and used, and retaining it only for as long as necessary. Clear agreements, secure data-sharing practices and prompt reporting of any suspected breach help build trust and reduce the risk of harm to customers.

Review service levels, costs and contract terms.

When choosing a network security services company, review its service levels, costs and contract terms carefully. Check what support is included, how quickly the provider will respond to alerts or incidents, and whether assistance is available outside normal business hours. Ask for a clear breakdown of fees, including any setup charges or extra costs, and confirm how the contract handles renewals, cancellations, changes in service and responsibilities for protecting your data. A clear agreement helps you compare providers and avoid unexpected costs or gaps in support.

Request regular reports and security assessments.

Request regular reports and security assessments from your network security services company to keep track of your organisation’s security posture. Clear, timely reports should summarise detected threats, vulnerabilities and changes, while recommending practical steps to address them. Regular assessments can also reveal new risks as your systems and business needs evolve, helping you prioritise improvements before weaknesses are exploited.

Test the provider’s incident response plan together.

Test the provider’s incident response plan together before an emergency occurs. Run a practical exercise based on a realistic scenario, such as a compromised account or suspected data breach, and check how quickly the provider identifies the issue, who is contacted and how updates are shared. Agree each party’s responsibilities, escalation routes and decision-making authority, then record any gaps and improvements. Regular joint testing helps ensure the plan works in practice and that everyone knows what to do under pressure.

Untangle Firewall: An Overview

Untangle firewall is a network security platform designed to help organisations control internet access, protect devices and manage traffic passing through their networks. It is best known for its modular approach: administrators can combine firewalling with additional security and monitoring tools to suit their requirements.

The product was historically known as Untangle NG Firewall. Following Untangle’s acquisition by Arista Networks, it has also been referred to as Arista NG Firewall. Product names, features and licensing can change, so check the provider’s current documentation before choosing or deploying it.

What Does Untangle Firewall Do?

At its core, a firewall monitors network traffic and applies rules to decide what should be allowed or blocked. Untangle extends this role with tools that can help administrators inspect traffic, manage users’ access to online services and respond to potential threats.

Depending on the edition and configuration, available capabilities may include:

  • Firewall rules: Control traffic by factors such as source, destination, service or network interface.
  • Intrusion prevention: Inspect traffic for patterns associated with known attacks.
  • Web filtering: Restrict access to websites by category or policy.
  • Application control: Identify or manage the use of selected applications and online services.
  • VPN access: Connect remote users or sites to a protected network, subject to the available configuration.
  • Reporting and monitoring: Review traffic and security events to support troubleshooting and policy decisions.

Not every capability is necessarily included in every version or subscription. Administrators should confirm which features are available and how they are licensed.

How Its Modular Design Works

Untangle’s interface has traditionally presented many security functions as separate applications or modules. This can make it easier to enable only the tools a network needs, rather than managing a single, fixed set of features.

That flexibility also calls for careful planning. Enabling several inspection and filtering tools may affect performance, particularly on a busy network or on hardware with limited resources. A sensible deployment starts with the organisation’s security requirements, expected traffic levels and available hardware.

Deployment Options

Untangle firewall has been available for deployment on dedicated appliances and compatible hardware, as well as in virtualised environments. The right option depends on the size and layout of the network, the organisation’s IT skills and its approach to maintenance.

Before installation, plan where the firewall will sit in the network, how internal and external connections will be configured, and how administrators will reach the management interface. It is also important to have a recovery plan in case a change disrupts access to the internet or business systems.

Potential Benefits

  • Centralised administration: Firewall and related security settings can be managed through a shared interface.
  • Configurable protection: Modular tools can help tailor policies to different users, devices or network needs.
  • Traffic visibility: Reports can help teams understand network use and investigate unusual activity.
  • Support for smaller IT teams: A combined platform may reduce the need to administer several separate products, depending on the organisation’s setup.

Points to Consider

A firewall is only one part of a broader security strategy. It cannot replace secure passwords, multi-factor authentication, timely software updates, endpoint protection, reliable backups or staff awareness. Nor does installing a firewall guarantee that a network is secure.

Organisations should also assess performance, update frequency, support arrangements, licensing costs and integration with existing systems. Security features need to be configured and maintained; default settings may not meet an organisation’s requirements. Regularly reviewing firewall rules and investigating alerts can help keep the deployment effective.

Is Untangle Firewall Right for Your Organisation?

Untangle firewall may be worth considering for organisations seeking a centrally managed platform that combines firewall controls with additional network security functions. Whether it is the right choice depends on the required features, the size of the network, available hardware, budget and the level of technical support needed.

Before committing, compare the current product offering with other firewall platforms, test it in a controlled environment where possible, and confirm that it meets your security and compliance requirements. A well-planned deployment, supported by ongoing monitoring and maintenance, is essential to getting value from any firewall solution.

SDN Security: Best Practices for Protecting Software-Defined Networks

SDN Security: Protecting the Software-Defined Network

Software-defined networking (SDN) changes how networks are managed. Rather than configuring every network device individually, SDN uses software to control and coordinate network behaviour. This can make networks more flexible and easier to manage, but it also introduces security considerations that organisations need to address.

Effective SDN security protects the network’s controllers, devices, applications and communications. It also helps ensure that network policies are applied consistently, even as infrastructure changes.

What is software-defined networking?

In a traditional network, control functions are distributed across routers and switches. SDN separates the network’s control plane, which decides how traffic should be handled, from its data plane, which forwards that traffic. A centralised or logically centralised SDN controller communicates with network devices and directs their behaviour.

Applications can interact with the controller through northbound interfaces, while the controller communicates with network devices through southbound interfaces. The exact architecture and protocols vary between SDN platforms, but the broad principle is the same: network behaviour is managed through software and policies.

Why does SDN security matter?

Centralised management can improve visibility and make it quicker to apply security policies across a network. For example, administrators may be able to isolate a compromised device or restrict access to a sensitive service without changing each switch manually.

However, the controller has significant influence over the network. If it is compromised, misconfigured or unavailable, an attacker or technical fault could affect many devices at once. SDN also relies on software, APIs and communication channels that may create new points of exposure. Security needs to be built into the architecture, rather than added only after deployment.

Common SDN security risks

  • Controller compromise: An attacker who gains access to the controller may be able to change network policies, redirect traffic or disrupt services.
  • Unauthorised access: Weak authentication, excessive privileges or poorly managed administrator accounts can expose controllers and management interfaces.
  • Insecure APIs: Vulnerabilities in northbound or southbound interfaces can allow unauthorised commands, data exposure or misuse of network functions.
  • Insecure communications: Traffic between controllers, applications and network devices could be intercepted or altered if it is not appropriately protected.
  • Misconfiguration: Incorrect policies can unintentionally allow traffic between systems that should be isolated, or block legitimate services.
  • Denial-of-service attacks: A flood of requests or network events may overwhelm a controller or the services it depends on.
  • Compromised applications or devices: Vulnerabilities in connected applications, switches, routers or virtual network functions can provide a route into the wider environment.
  • Limited visibility: Rapidly changing, virtualised networks can make it harder to identify unusual activity unless monitoring covers both the control and data planes.

Best practices for securing an SDN environment

Protect the controller

Treat SDN controllers as critical infrastructure. Place them in a restricted management environment, limit administrative access and apply security updates promptly. Use strong authentication, including multi-factor authentication where available, and assign permissions according to each user’s responsibilities. Avoid exposing management interfaces directly to untrusted networks.

Secure APIs and communications

Use authenticated and encrypted communication between controllers, applications and network devices wherever supported. Validate API inputs, manage credentials securely and disable interfaces or services that are not required. Review API permissions regularly, particularly when applications or integrations change.

Apply least privilege and separation of duties

Users, applications and devices should receive only the access they need. Separate administrative duties where practical, and use distinct accounts for routine tasks and privileged operations. This can limit the impact of a compromised account or an accidental change.

Segment the network

Use network segmentation to separate sensitive systems, management traffic and user workloads. Define clear rules for communication between segments and review them regularly. SDN can help automate segmentation, but the policies still need careful design and testing.

Monitor network activity

Collect and review logs from controllers, network devices and relevant applications. Monitor for unexpected policy changes, unusual administrative activity, abnormal traffic patterns and repeated authentication failures. Integrating SDN logs with security monitoring tools can help teams investigate events across the wider environment.

Test changes before deployment

Network policies can have far-reaching effects. Test changes in a controlled environment where possible, use staged roll-outs and keep a record of approved changes. Establish a clear process for reviewing, authorising and, if necessary, reversing policy updates.

Plan for resilience and recovery

Consider how the network will behave if a controller, link or supporting service becomes unavailable. Depending on the platform, resilience may involve controller redundancy, backups, recovery procedures and tested failover arrangements. Document how to restore service and practise the relevant procedures.

Assess the supply chain

SDN environments may depend on software from multiple suppliers, including controller platforms, applications and virtual network functions. Assess supplier security practices, keep an inventory of components and track relevant updates and vulnerabilities. Use trusted sources for software and verify that components are supported.

Building an SDN security strategy

There is no single configuration that suits every SDN deployment. A sound security strategy starts with an understanding of the network’s architecture, critical assets, data flows and operational requirements. From there, organisations can identify likely threats, set security objectives and decide how controls will be implemented and tested.

Security should be considered throughout the SDN lifecycle: during design, deployment, day-to-day operation and decommissioning. Regular reviews help ensure that policies remain appropriate as applications, users and network services change.

Conclusion

SDN can make networks more adaptable and improve the consistency of network management. Its centralised control and reliance on software also mean that controllers, APIs, communications and policies need strong protection. By applying least privilege, securing interfaces, monitoring activity, testing changes and planning for recovery, organisations can reduce risk and make SDN a more resilient part of their security architecture.

 

8 Essential Tips for Securing Software-Defined Networks (SDN)

  1. Secure the controller with strong authentication.
  2. Encrypt control-plane communications.
  3. Segment management and data networks.
  4. Apply least-privilege access controls.
  5. Keep SDN software and firmware patched.
  6. Monitor flows for unusual activity.
  7. Validate rules before deploying changes.
  8. Back up controller configurations regularly.

Secure the controller with strong authentication.

Secure the SDN controller with strong authentication to help prevent unauthorised access to a critical part of your network. Use unique accounts, strong passwords and multi-factor authentication where available, and avoid shared administrator credentials. Give each user only the permissions needed for their role, review access regularly and remove accounts promptly when they are no longer required. These measures can reduce the risk of an attacker taking control of network policies or disrupting services.

Encrypt control-plane communications.

Encrypt control-plane communications to protect instructions and status data exchanged between SDN controllers, network devices and applications. Encryption helps prevent attackers from intercepting or tampering with this traffic, which could otherwise expose sensitive information or lead to unauthorised network changes. Use secure, supported protocols, validate the identity of communicating endpoints and manage certificates and keys carefully, including renewing them before they expire.

Segment management and data networks.

Keep management traffic separate from the data network to reduce the risk of an attacker reaching SDN controllers and administrative interfaces through compromised user devices or services. Use dedicated network segments, restrict access to authorised systems and administrators, and apply firewall rules that allow only the connections required for management. Regularly review segmentation policies and monitor traffic between segments to spot unauthorised access or unexpected changes.

Apply least-privilege access controls.

Apply least-privilege access controls across your SDN environment by giving users, applications and devices only the permissions they need to perform their roles. Restrict access to controllers and management interfaces, use strong authentication and review privileges regularly, especially when responsibilities change. This limits the damage a compromised account or misconfigured application can cause and helps prevent unauthorised changes to network policies.

Keep SDN software and firmware patched.

Keep SDN software and firmware patched to protect controllers, switches, routers and related components from known vulnerabilities. Apply security updates promptly, following a controlled process that includes checking vendor guidance, testing changes where possible and keeping a recovery plan in place. Regular patching reduces the risk of attackers exploiting outdated systems to disrupt network services or gain unauthorised access.

Monitor flows for unusual activity.

Monitor network flows for unusual activity to help spot potential threats early. Establish a baseline of normal traffic between users, devices and services, then look for deviations such as unexpected connections, unusual data volumes, unfamiliar destinations or sudden changes in communication patterns. In an SDN environment, flow monitoring can provide valuable visibility across dynamically changing networks, helping security teams investigate suspicious behaviour and apply containment policies promptly. Tune alerts to reduce false positives, and review them regularly as network activity evolves.

Validate rules before deploying changes.

Validate SDN rules before deploying changes to ensure they work as intended and do not introduce security gaps or disrupt legitimate traffic. Test policies in a controlled environment where possible, check how they interact with existing rules, and obtain the appropriate approval before rolling them out. A staged deployment and a clear rollback plan can help limit the impact if an issue arises.

Back up controller configurations regularly.

Back up SDN controller configurations regularly so they can be restored if a controller fails, is compromised or a configuration change causes disruption. Store backups securely, restrict access and keep copies separate from the controller itself. Test the restoration process periodically, as a backup is only useful if it can be recovered successfully.

Untangle NG Firewall: An Overview

Untangle NG Firewall is a network security platform designed to help organisations monitor and protect the traffic passing through their networks. It combines traditional firewall controls with a collection of security and network-management tools, making it possible to manage several protections from one interface.

The product was developed by Untangle, which Arista Networks acquired in 2021. It is now commonly referred to as Arista NG Firewall. Product names, licensing and availability may change over time, so organisations considering it should check the current information from Arista before making a purchasing or migration decision.

How it works

NG Firewall is typically placed between an organisation’s internal network and its internet connection. Traffic passes through the appliance, where configured rules and security services can inspect it. The firewall can run on dedicated hardware or, depending on the version and deployment requirements, in a virtual environment.

A notable feature of the platform is its app-based design. Rather than presenting every capability as a separate product, it groups functions into applications that administrators can enable and configure to suit their network.

Key features

  • Firewall controls: Create rules to manage network traffic and restrict unwanted connections.
  • Intrusion prevention: Inspect traffic for activity associated with known attacks and suspicious behaviour.
  • Web filtering: Apply policies to web access, such as limiting access to selected categories or sites.
  • Malware protection: Use supported scanning tools to help identify threats in network traffic.
  • Virtual private networking: Provide secure remote access or connections between locations, subject to the available configuration and licence.
  • Reporting and monitoring: Review network activity and security events through dashboards and reports.
  • Traffic management: Apply bandwidth policies and manage how network resources are used.

Not every feature is necessarily included in every edition or subscription. Administrators should confirm which services are available, how they are licensed and what hardware or system resources they require.

Who might use it?

Untangle NG Firewall may suit small and medium-sized organisations that want a central point for managing internet access and network security. It can also be of interest to IT teams looking for a single interface for firewall rules, web policies, traffic visibility and related controls.

Suitability depends on the size and complexity of the network. Larger organisations may need to assess its high-availability options, central management capabilities, integration with existing security tools and performance under expected traffic loads. A trial or controlled pilot can help establish whether it meets operational requirements.

Benefits and considerations

The app-based approach can make it easier to enable the protections a network needs without deploying a separate appliance for every function. Centralised reporting may also help administrators understand what is happening on the network and investigate issues.

However, a firewall is only one part of a security programme. It needs careful configuration, regular updates and ongoing review. Administrators should also consider the impact of encrypted traffic inspection, privacy obligations, logging and data retention. As with any gateway security product, incorrect rules or an overloaded appliance can affect both protection and network performance.

Planning a deployment

Before installing NG Firewall, document the network layout, internet connection speed, number of users and the services that must remain accessible. Check the product’s current compatibility and sizing guidance, then plan how the appliance will fit into the network and how administrators will access it if a configuration change causes a problem.

After deployment, test key services, review alert and reporting settings, and establish a routine for updating the system and checking firewall rules. Keep a record of configuration changes and make sure there is a recovery plan, including backups where supported.

Conclusion

Untangle NG Firewall, now associated with the Arista NG Firewall name, brings firewalling and a range of network security tools together in a single platform. Its feature set and app-based design may be useful for organisations seeking consolidated network management. The best way to assess it is to compare its current capabilities, licensing, support and performance requirements with the needs of the network it is intended to protect.

 

7 Essential Tips for Securing Untangle NG Firewall

  1. Keep Untangle NG Firewall updated.
  2. Use strong, unique administrator passwords.
  3. Enable only the apps and features you need.
  4. Back up your configuration regularly.
  5. Review firewall rules and logs often.
  6. Test changes before applying them widely.
  7. Restrict admin access to trusted networks.

Keep Untangle NG Firewall updated.

Keep Untangle NG Firewall updated to ensure it has the latest security fixes, feature improvements and compatibility updates. Check for updates regularly, review the release notes before installing them, and schedule upgrades at a suitable time to minimise disruption. Before a major update, back up the configuration and confirm that you have a recovery plan in case anything goes wrong.

Use strong, unique administrator passwords.

Use a strong, unique password for every Untangle NG Firewall administrator account. A long passphrase made from several unrelated words can be easier to remember and harder to guess; avoid reusing passwords from other services or using predictable details. Store credentials securely in a reputable password manager, limit administrator access to people who need it, and enable multi-factor authentication if it is available in your setup. Regularly review accounts and remove access that is no longer required.

Enable only the apps and features you need.

Enable only the apps and features your network needs in Untangle NG Firewall. Each additional service can use system resources and may introduce settings that need monitoring, so a focused configuration can help maintain performance and make the firewall easier to manage. Review your requirements regularly and enable further features only when there is a clear need.

Back up your configuration regularly.

Back up your Untangle NG Firewall configuration regularly, especially after making significant changes to firewall rules, network settings or security applications. A recent backup can help you restore your setup more quickly if the appliance fails, an update causes problems or a configuration change interrupts network access. Store backup files securely, keep copies separate from the firewall itself, and check periodically that they’re available when needed.

Review firewall rules and logs often.

Review firewall rules and logs regularly to make sure your Untangle NG Firewall is protecting the network as intended. Remove outdated or overly broad rules, check that permitted traffic is still necessary, and investigate unusual activity or repeated blocked connections in the logs. Routine reviews can help uncover misconfigurations and potential threats before they cause wider problems.

Test changes before applying them widely.

Before rolling out a new rule or configuration across your network, test it on a small, controlled group of users or devices. This helps you spot blocked services, unexpected alerts or performance issues without disrupting everyone’s access. Once the change has been checked and any problems resolved, apply it more widely and continue monitoring the firewall’s logs and reports.

Restrict admin access to trusted networks.

Restricting administrator access to trusted networks helps reduce the risk of unauthorised changes to your Untangle NG Firewall. Configure management access so it is available only from designated internal networks, secure administrator accounts with strong, unique passwords and multi-factor authentication where supported, and avoid exposing the management interface directly to the internet. Review access rules regularly and remove any networks or accounts that are no longer needed.

Rather than focusing primarily on displaying individual packets, it organises captured data into useful information about hosts, connections and transferred files. This can make it easier to investigate what happened during a network incident.

What is NetworkMiner?

Developed by Netresec, NetworkMiner is used to analyse packet capture files, commonly known as PCAP files. It can identify hosts and network sessions, and may extract artefacts such as files, images, certificates and credentials when they are present in supported traffic. The results depend on the protocols used, the quality of the capture and whether the relevant information is visible.

NetworkMiner is often described as a passive network forensic analysis tool. It examines traffic that has already been captured, rather than actively interacting with the systems being investigated. This makes it useful for reviewing a saved capture after a security alert or suspected intrusion.

What can NetworkMiner help with?

  • Host identification: View systems observed in the capture and details that may help distinguish them.
  • Session analysis: Review communications between hosts and the services involved.
  • File extraction: Recover files transferred in supported protocols, where the capture contains enough data.
  • Artefact review: Examine other available evidence, such as images, certificates or credentials exposed in unencrypted traffic.
  • Incident investigation: Build a clearer picture of network activity for security monitoring, troubleshooting or digital forensics.

How does it fit into an investigation?

A typical workflow begins with collecting network traffic using an authorised capture process. The resulting PCAP file can then be opened in NetworkMiner for an initial overview of hosts, sessions and potential artefacts. Investigators can use those findings to decide which traffic needs closer examination.

NetworkMiner can complement packet analysers such as Wireshark. Its host-centred presentation and artefact extraction can make certain investigative tasks quicker, while a packet analyser offers detailed control over individual packets and protocol fields. The tools serve related but different purposes, so using them together can be helpful.

Important limitations

NetworkMiner can only analyse information available in the capture. If traffic was missed, the capture began too late, or the relevant content is encrypted, the tool may not be able to recover the details an investigator is looking for. Modern encryption often prevents the contents of a connection from being read, although some connection metadata may still be visible.

Results also need to be interpreted carefully. An extracted artefact or identified host is evidence to investigate, not necessarily proof of malicious activity on its own. Good practice includes preserving the original capture, documenting how it was obtained, recording analysis steps and corroborating findings with other evidence.

Choosing a version

NetworkMiner is available in different editions, including a free Community Edition and a commercial Professional Edition. Features and licensing can change, so check the developer’s website for current details before choosing a version. Organisations should also review the licence terms and test the software with representative captures before relying on it in operational workflows.

Use it responsibly

Network captures can contain sensitive information, including personal data and confidential business communications. Only capture or analyse traffic when authorised, follow applicable privacy and data-protection requirements, and restrict access to capture files and extracted artefacts.

Conclusion

NetworkMiner is a useful option for turning packet captures into an organised view of network activity. Its ability to group information around hosts and identify recoverable artefacts can support incident response and forensic investigations. Like any analysis tool, it works best when used alongside sound evidence-handling practices and a clear understanding of what the capture can—and cannot—show.

 

8 Tips for Safe and Effective Network Analysis with NetworkMiner

  1. Use NetworkMiner to analyse PCAP files without altering the original capture.
  2. Capture only traffic you are authorised to inspect.
  3. Check the Hosts tab to identify systems and their network activity.
  4. Review the Files tab to recover files observed in the capture.
  5. Use the DNS tab to spot queried domains and potential anomalies.
  6. Treat extracted credentials as sensitive and store them securely.
  7. Compare findings with other tools before drawing conclusions.
  8. Keep captures and reports protected, as they may contain personal data.

Use NetworkMiner to analyse PCAP files without altering the original capture.

Use NetworkMiner to examine PCAP files while keeping the original capture intact. Analyse a working copy where possible, store the source file securely and record the steps taken during your investigation. This helps preserve the evidence for later review and makes your findings easier to verify.

Capture only traffic you are authorised to inspect.

Capture only traffic you are authorised to inspect. NetworkMiner can reveal sensitive details from network traffic, so only collect or analyse data when you have clear permission to do so. Follow your organisation’s policies and applicable privacy and data-protection requirements, and store capture files securely with access limited to authorised people.

Check the Hosts tab to identify systems and their network activity.

Check the Hosts tab in NetworkMiner to see which systems appear in the capture and review their associated network activity. This can help you quickly identify relevant devices, understand which hosts communicated and decide where to focus your investigation. Remember that the information shown depends on the traffic captured, so treat it as a starting point and verify important findings against the underlying evidence.

Review the Files tab to recover files observed in the capture.

Review the Files tab in NetworkMiner to see files identified in the network capture. Where the traffic contains enough data and the transfer uses a supported protocol, you may be able to recover files for further analysis. Check the file details and related session carefully, and remember that encrypted, incomplete or unsupported traffic may prevent recovery.

Use the DNS tab to spot queried domains and potential anomalies.

Use NetworkMiner’s DNS tab to review the domains queried in a capture and spot anything that looks out of place. Unfamiliar or misspelt domain names, unexpected top-level domains, or repeated queries to a single host may warrant closer investigation. Treat these as clues rather than proof of malicious activity, and check them against the surrounding traffic and other available evidence.

Treat extracted credentials as sensitive and store them securely.

Treat any credentials extracted with NetworkMiner as highly sensitive information. They may provide access to user accounts, systems or services, so avoid sharing them unnecessarily and never include them in reports or screenshots without appropriate redaction. Store them only in an approved, access-controlled location, protect them with encryption where possible, and follow your organisation’s retention and disposal policies. If a credential may have been exposed or compromised, notify the relevant security team and arrange for it to be changed.

Compare findings with other tools before drawing conclusions.

Compare NetworkMiner’s findings with evidence from other tools before drawing conclusions. Cross-check hosts, sessions and extracted artefacts against packet-level analysis in tools such as Wireshark, as well as relevant logs and endpoint data. This can help confirm that an observation is accurate, provide useful context and reduce the risk of treating an incomplete or misleading result as proof of malicious activity.

Keep captures and reports protected, as they may contain personal data.

Network captures and reports can contain personal data, credentials and details of private communications, so treat them as sensitive information. Store them in access-controlled locations, share them only with authorised people and use encryption where appropriate. Keep them only for as long as necessary, following your organisation’s retention and data-protection policies, and securely delete them when they are no longer needed.
