What is It?

A firewall security audit is a structured review of your firewall rule set, configuration, NAT policies, security profiles and logging setup. We identify overly permissive rules, redundant entries, bypass risks, missing critical controls and firmware vulnerabilities.

Codesecure's firewall audit is delivered by certified consultants experienced with Cisco, Palo Alto, Fortinet, Check Point, Sophos and pfSense. Output includes a hardened ruleset recommendation, NAT optimization, security profile tuning and a prioritized remediation roadmap.

Why It Matters

Firewall rule sets grow organically over time, accumulating exceptions, vendor allow-lists and 'temporary' rules that become permanent. A 5-year-old enterprise firewall typically has 30-60% of rules that are unused, redundant or overly permissive, creating attack paths.

Indian banks, NBFCs and large enterprises must demonstrate firewall security maturity for RBI, PCI DSS and ISO 27001 compliance. Annual firewall audit is a baseline supervisory expectation; semi-annual review is best practice for high-change environments.

What We Test

Comprehensive coverage of the most exploitable risk categories for this service:

Rule Set ReviewOverly permissive rules, redundancy, shadowing, contradictions
Default Deny ValidationFinal implicit deny, allow-all rules, missing baseline controls
Time-Based RulesTemporary access expiry, vendor windows, contractor access cleanup
NAT & RoutingBidirectional NAT, hairpin risks, routing-table inconsistencies
Application-Layer FilteringNGFW application policies, URL filtering, SSL inspection setup
IPS/IDS ConfigurationSignature coverage, blocking mode, exclusion review, custom signatures
Logging & SIEM IntegrationLog forwarding, retention, blocked traffic visibility, alert tuning
Authentication & ManagementAdmin access controls, MFA, RBAC, separation of duties
Firmware & PatchesCVE exposure, vendor patch status, recommended upgrade paths
High AvailabilityFailover testing, configuration sync, redundancy validation

Frequently Asked Questions

What firewall vendors do you support?

Cisco ASA/FTD/FirePOWER, Palo Alto PAN-OS, Fortinet FortiGate, Check Point, Sophos XG, pfSense, Juniper SRX, Microsoft Azure Firewall, AWS Network Firewall. Multi-vendor environments supported in a single engagement.

Do you need physical access to the firewall?

No. Configuration exports, read-only API/CLI access or backup files are sufficient. We work entirely from configuration data with optional packet captures for validation.

How long does a firewall audit take?

Most firewalls complete in 3-7 days. Single firewall with under 200 rules: 3 days; complex multi-firewall environments: 5-10 days. Instant response means testing starts same/next business day after scoping.

What does it cost in INR?

Pricing starts from INR 25,000 and varies by firewall count, vendor mix and rule volume. Fixed price after free 30-minute scoping call.

How quickly can you start?

Instant response, no delay. Response within an hour during business hours, proposal within 24-48 hours under signed NDA, audit starts same/next business day after configuration access provided.

Will the audit affect firewall performance?

No. The audit is configuration-based, read-only. We do not push changes or apply policies; we provide a recommended ruleset for your team to implement under change control.

Do you implement the recommended changes?

Optional. We provide detailed remediation guidance with the audit. Implementation assistance available as a separate engagement with your team or under managed firewall services.
