Firewall Testing Services

A Firewall Is Only Effective If It's Configured To Be.

Firewalls are a cornerstone of network security but a misconfigured or poorly maintained ruleset can provide a false sense of protection while leaving your organisation dangerously exposed. Over time, firewall rules accumulate, complexity grows, and weaknesses quietly emerge that technical teams may not have the capacity to identify.

Our firewall testing and review service combines active penetration testing with a thorough configuration audit, ensuring your perimeter defences are genuinely effective rather than simply present.

The Process

A Thorough Review Process, From Rule Set to Real-World Behaviour

Firewall review is a methodical discipline. Rushing it produces findings that miss context; approaching it without structure produces findings that are difficult to act on.

Our methodology is designed to give the review the attention it deserves with a scoping process that captures the details, a structured review approach that examines both individual rules and the cumulative effect of the rule set as a whole, and a reporting process that presents findings in a way your network team can act on without a lengthy translation process. We also validate findings behaviourally, confirming that rules function as configured not just as documented.

Benefits of Firewall Security Testing

As Strong as Its Configuration

A firewall is often treated as a guarantee of security but its effectiveness depends entirely on how it's configured. Overly permissive rules, legacy exceptions, and configuration drift over time can leave your firewall providing far less protection than you assume.

Our firewall security testing gives you an independent, expert review of your firewall configuration and rule sets, confirming whether your perimeter control is functioning as your security policy intends or leaving gaps that put your organisation at risk.

Firewall Reviews That Look Beyond the Surface

Firewall configuration review is a discipline that rewards genuine expertise. The accumulated rule sets of a firewall that's been in service for several years are often complex, inconsistent, and difficult to interpret without significant experience and context.

Our consultants bring that experience. We review firewall rule sets with a structured, methodical approach identifying overly permissive rules, legacy exceptions that should have been removed, inconsistencies between policy intent and actual configuration, and opportunities to tighten your perimeter without disrupting business operations.We also test firewall behaviour directly, confirming that rules are functioning as configured and that traffic is being handled as intended.

Configuration review and behavioural testing together give you a complete, reliable picture of your firewall security posture. Our findings are communicated clearly, with recommendations structured for both network engineers and business stakeholders who need to understand the implications of what we've found.
