Secarma Insight
Why is a Firewall Configuration Review Important?

Firewalls are often the first barrier between your systems and external threats. But outdated rules, overly broad access, and poor documentation can turn that barrier into a liability. This review provides clarity, control, and a clear path forward for remediation.

Reduce the Attack Surface

Eliminate unnecessary exposure by removing outdated, overly permissive, or redundant rules that increase risk.

Improve Visibility

Gain a clear understanding of what your firewalls are actually allowing—and why—with visual mapping and flow analysis.

Provide an Actionable Roadmap

Receive tailored recommendations and prioritised fixes to help you improve posture without disrupting operations.
