Perimeter Defense

Network Security

Firewall, network architecture, and perimeter defense — validated and hardened before attackers find the gaps.

Your network perimeter is the first line of defense, and it's rarely as tight as it should be. We go beyond automated scanning to manually review firewall rule sets, NGFW policies, network segmentation, and cloud perimeter configuration — identifying overly permissive rules, shadowed policies, unpatched firmware, and architecture-level exposure across perimeter firewalls, NGFWs, WAFs, and cloud security groups.

What's Included

Every engagement under Network Security 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.

Network Segmentation & Architecture Review

Assess VLAN segmentation, zone-based trust boundaries, and east-west traffic controls to limit how far an attacker or compromised device can move.

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.

Delivery Framework

01

Scope & Access Setup

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

02

Configuration Export & Analysis

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

03

Risk Classification

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

04

Remediation Report

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

05

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.
