6 Core Pillars of Firewall & Network Auditing

Our certified network security engineers and firewall architects analyze rulebases, inspection profiles, and routing policies to eliminate security exposure.

Rulebase Optimization & Pruning

Algorithmic analysis of shadowed, redundant, expired, and overly permissive (ANY-ANY-ALLOW) rules to eliminate performance latency and close accidental backdoors.

  • Shadowed & duplicate rule identification
  • Unused & expired rule cleanup
  • Overly broad ANY-ANY rule remediation

NGFW Deep Packet Inspection

Auditing SSL/TLS decryption policies, IPS/IDS signature updates, application ID (App-ID) enforcement, and DNS sinkholing to block command-and-control (C2) beacons.

  • SSL/TLS inbound/outbound decryption check
  • IPS/IDS active prevention verification
  • Malicious URL filtering & DNS sinkholing

DMZ & Micro-Segmentation

Evaluating network zoning architectures, DMZ isolation from core internal LANs, cloud VPC security groups, and stopping lateral adversary movement.

  • DMZ to Internal LAN isolation audit
  • East-West lateral movement restrictions
  • Cloud VPC & hybrid network security groups

Appliance OS & Admin Hardening

Verifying management interface binding to dedicated OOB networks, disabling insecure protocols (Telnet/HTTP), enforcing TACACS+/MFA, and applying OS CVE hotfixes.

  • Out-of-band management plane protection
  • TACACS+ / RADIUS with MFA enforcement
  • Firewall firmware CVE vulnerability patch check

PCI-DSS & RBI Compliance

Validating documented firewall change management processes, semi-annual rule reviews, cardholder data environment (CDE) boundaries, and SIEM logging.

  • PCI-DSS Requirement 1 compliance check
  • RBI Cyber Security Framework validation
  • Firewall change approval audit trails

CLI Clean-Up & Safe-to-Host

Delivering vendor-specific CLI configuration commands (Palo Alto, FortiGate, ASA), conducting post-patch retesting, and issuing the Safe-to-Host Certificate.

  • Ready-to-execute CLI cleanup scripts
  • Free 30-day rule retesting verification
  • CERT-In Safe-to-Host Firewall Certificate

5-Stage Firewall Review & Assessment Roadmap

Our certified network security specialists execute a non-disruptive, offline configuration evaluation lifecycle.

1
STAGE 1: TOPOLOGY & CONFIGURATION INTAKE

Rulebase & Architecture Scoping

Collecting sanitized firewall configuration files (XML / CLI dumps), routing tables, and network topology diagrams under strict NDA without live network impact.

2
STAGE 2: AUTOMATED RULEBASE OPTIMIZATION

Algorithmic Shadowing & Pruning Analysis

Processing configuration files with automated analytics engines to identify shadowed rules, unused objects, and calculate rulebase complexity scores.

3
STAGE 3: MANUAL POLICY & SEGMENTATION AUDIT

Zero-Trust & Deep Packet Inspection Review

Senior network security auditors manually evaluate DMZ boundaries, IPS profiles, SSL decryption rules, and administrative access controls.

4
STAGE 4: TECHNICAL DEBRIEF & CLI SCRIPTS

Actionable Remediation & Pruning Guide

Delivering prioritized CVSS v3.1 reports with vendor-tailored CLI commands, helping network engineers prune rules with zero operational downtime.

5
STAGE 5: RETESTING & SAFE-TO-HOST CERTIFICATION

Verification & Compliance Attestation

Validating updated rulebases during a 30-day retest window and issuing the official Lumiverse Safe-to-Host Network Security Certificate.

Frequently Asked Questions

Key details on firewall audit safety, multi-vendor support, and compliance frequency.

No. Our firewall review is conducted offline using sanitized configuration exports and read-only API inspection. We never modify live configurations or inject high-volume disruptive traffic without explicit maintenance window approval.
We support all leading enterprise firewall brands including Palo Alto Networks (PAN-OS), Fortinet (FortiGate), Check Point (Gaia), Cisco (Firepower / ASA), Juniper (Junos), pfSense, Sophos, and cloud-native firewalls (AWS Network Firewall, Azure Firewall).
Regulatory frameworks like PCI-DSS Req 1.1.7 and RBI Cyber Security Guidelines mandate formal firewall rule reviews at least once every six months, or immediately following significant network topology changes.
