Our Process
We identify all firewalls in scope and obtain read-only access to configuration files and management consoles.
We export firewall configurations, rule bases, and policy objects for analysis in a secure, isolated environment.
Automated policy analysis identifies shadow rules, redundant rules, any-any permissions, and compliance deviations at scale.
Our firewall specialists manually review findings, assess business context, and identify risks that automated analysis may miss.
Findings are rated by severity critical rules that directly expose the network are prioritised above housekeeping recommendations.
Full technical report with rule-level findings, a rationalised ruleset recommendation, and an executive summary for leadership.
Frequently Asked Questions
Do you need live access to our firewall management console?
No. Our firewall configuration audit can be performed using exported configuration files, which is our preferred approach for minimizing operational risk. Where live access provides additional value, we use secure, read-only credentials to conduct the firewall security assessment without making unauthorized changes.
Which firewall vendors do you support?
Our firewall security audit services support major enterprise firewall platforms, including Palo Alto Networks, Fortinet FortiGate, Cisco ASA and FTD, Check Point, Juniper SRX, and Sophos. We review firewall configurations, access-control rules, security policies, NAT rules, objects, and other relevant settings based on the platform.
How many firewall rules can you analyse?
Our firewall configuration audit services can handle large and complex rulesets containing tens of thousands of rules. We combine automated analysis with expert manual review to identify issues such as redundant rules, overly permissive access, shadowed rules, unused rules, and policy misconfigurations.
What does a firewall security audit include?
A firewall security audit typically includes configuration review, access-control policy analysis, rule-base assessment, network segmentation review, NAT and object analysis, overly permissive rule identification, unused and redundant rule detection, and security best-practice validation. We provide prioritized findings and remediation recommendations.
Do you provide firewall audit services in India?
Yes. Our firewall audit services in India help organizations identify configuration weaknesses, policy gaps, unnecessary exposure, and security risks across enterprise firewall environments. The assessment can be tailored to your network architecture, firewall platform, and compliance requirements.
Why is a firewall configuration audit important?
A regular firewall configuration audit helps ensure that security policies remain aligned with your organization’s current network architecture and business requirements. It can identify outdated, overly permissive, redundant, or misconfigured rules that could increase the risk of unauthorized access and network compromise.
