Firewall, Segmentation & Policy Hardening
We harden perimeter and internal network controls with practical segmentation strategies and risk-based firewall policies. Our goal is to reduce your attack surface without disrupting legitimate business traffic.
We conduct a full rule-base review to identify unused, overly permissive, or conflicting rules. Changes are implemented incrementally with business owner sign-off, documented rollback steps, and post-change traffic validation to confirm no unintended disruption.
