Your business has changed. Your network has changed. Your firewall rules have changed. But has your firewall kept up?
Over time, firewall configurations can become complex, outdated and difficult to manage. Rules may no longer reflect your current business requirements, legacy configurations can introduce unnecessary risk, and important security features may be underused or incorrectly configured.
A Firewall Health Check & Audit from ANSecurity provides an expert, independent assessment of your firewall environment, identifying security gaps, configuration issues, unnecessary complexity and opportunities to improve resilience and performance.
A firewall is only as effective as its configuration.
Our health check gives you a clear view of how your firewall is operating, where potential vulnerabilities or weaknesses exist, and what you can do to strengthen your security posture.
We assess your firewall holistically, looking beyond individual rules to understand the wider security, resilience and network environment.
Regular auditing can help organisations:
Ultimately, it provides confidence that your firewall is doing what you expect it to do — and protecting what matters most.
We recommend carrying out a Firewall Health Check & Audit once or twice a year for most organisations, although the appropriate frequency will depend on your environment and how frequently changes are made.
Organisations operating highly secure or complex environments may benefit from more frequent assessments.
A health check is particularly valuable following:
If your business has changed, your firewall should be reassessed too.
The assessment concludes with a comprehensive Firewall Health Check & Audit Report, giving your technical and leadership teams a clear understanding of the current state of your firewall environment.
The report includes:
A concise overview of the current firewall health, key risks and priority areas.
A detailed assessment of identified configuration, security and operational issues.
Practical, prioritised recommendations to help you improve security, resilience and firewall performance.
No jargon. No unnecessary complexity. Just clear insight into where you are today and what you should do next.
A typical assessment takes two days per firewall or High Availability cluster, based on an environment of up to 200 rules per firewall.
Day 1 – Assessment & Analysis
We gather intelligence, review the firewall configuration and analyse the platform, policies and wider environment.
Day 2 – Reporting & Recommendations
We consolidate our findings and produce a comprehensive report, including prioritised recommendations for improvement.
For larger or more complex environments, additional time may be required.
Your Firewall Health Check can be delivered remotely, on-site, or through a combination of both.
Typically, the initial assessment is carried out on-site, with the remaining analysis and reporting completed remotely. However, we can tailor the approach to suit your environment, requirements and security policies.
Every assessment is conducted by a certified security consultant with extensive real-world experience across complex enterprise environments.
At ANSecurity, our in-house consultants bring experience across a broad range of security technologies and complex environments, supporting organisations across finance, healthcare, manufacturing, education and other highly regulated sectors.
This breadth of experience means we don’t simply assess whether your firewall is configured correctly. We consider how it supports your wider security strategy, network architecture and business requirements.
Our consultants provide practical recommendations based on industry best practice and real-world experience — helping you make informed decisions about where to invest your time and security budget.
Your firewall is a critical part of your security infrastructure. Regular health checks can help ensure it remains secure, resilient, correctly configured and aligned with your business.
