Firewall Assessment

Validate, harden, and audit your firewall configurations to close gaps before attackers find them.

Misconfigured firewalls are one of the most common and most exploited security gaps in enterprise environments. Our firewall assessment goes beyond automated scanning — our engineers manually review rule sets, policy logic, and traffic flows to identify overly permissive rules, shadowed policies, unpatched firmware, and compliance deviations. We assess perimeter firewalls, next-gen firewalls (NGFW), WAFs, and cloud security groups.

What's Included

Every engagement under Firewall Assessment covers the following service areas — tailored to your environment and risk profile.

📋

Firewall Rule Set Review

Manual audit of all firewall rules — identifying overly permissive rules, redundant entries, shadowed policies, and any-to-any rules that violate least privilege.

🛡️

Next-Gen Firewall (NGFW) Assessment

Deep configuration review of Palo Alto, Fortinet, Cisco, and Check Point NGFWs — application control, IPS/IDS policies, threat profiles, and SSL inspection settings.

Web Application Firewall (WAF) Assessment

Evaluate WAF rule effectiveness against OWASP Top 10 attack vectors, identify bypass techniques, and tune rules to reduce false positives without opening attack surface.

☁️

Cloud Security Group & NACl Review

Audit AWS Security Groups, Azure NSGs, and GCP Firewall Rules for over-permissive inbound/outbound access, unused rules, and public exposure of sensitive ports.

Firewall Change Management Audit

Review change control processes, emergency change procedures, and rule lifecycle management to ensure governance controls prevent unauthorized or undocumented changes.

Delivery Framework

Scope & Access Setup

Define assessment scope — device inventory, firmware versions, access credentials, and read-only review access to rule sets.

Configuration Export & Analysis

Export firewall configs and run automated policy analysis tools alongside manual review of rule logic and traffic patterns.

Risk Classification

Classify each finding by risk level — critical exposure, compliance violation, best practice deviation, or informational — with business impact context.

Remediation Report

Deliver a prioritized report with exact rules to modify, remove, or add — including recommended replacement rule logic.

Post-Remediation Validation

Re-assess after your team applies fixes to confirm all critical and high findings are resolved and no new gaps were introduced.
