Firewall Assessment

Firewall rules accumulate over years. Most organizations have no idea what's actually allowed.

Firewalls are the first line of defense — but over time, rule sets grow bloated, contradictory, and full of legacy exceptions that nobody remembers creating. We perform a comprehensive review of your firewall configurations across Cisco, Fortinet, Palo Alto, and other platforms to identify overly permissive rules, redundant entries, and gaps that leave your network exposed.

What We Review

Rule Base Analysis

Full audit of firewall rules to identify any-any rules, unused rules, shadowed rules, and overly broad permissions that violate least-privilege principles.

Zone & Segmentation Review

Assessment of network zone design, inter-zone traffic policies, and DMZ configuration to ensure proper segmentation between trust levels.

NAT & VPN Configuration

Review of NAT rules, site-to-site VPN configurations, remote access VPN policies, and split-tunneling risks.

Logging & Alerting

Verification that logging is enabled for critical rule matches, that logs are forwarded to a SIEM, and that alerting thresholds are appropriate.
