Frequently Asked Questions

Find Quick Answers

What firewall configuration formats are supported?

The tool supports text-based configuration files from Cisco ASA (.txt, .conf), Palo Alto Networks (.xml, .conf), Fortinet FortiGate (.conf), Check Point, and Juniper SRX. Common extensions include .txt, .conf, .cfg, and .xml.

Is my firewall configuration data secure?

Yes, all uploaded files are processed securely and temporarily. Files are not stored permanently and are deleted after analysis. The analysis runs in an isolated environment with no external data sharing.

What types of security vulnerabilities does the analyzer detect?

The tool detects overly permissive rules (ANY/ANY), shadowed rules, rules with insecure services, missing logging, rules violating security best practices, and potential misconfigurations that could lead to security breaches.

Can I analyze multiple firewall configuration files at once?

Currently, the tool analyzes one configuration file at a time for focused, detailed analysis. For comparing multiple configurations, you can run separate analyses and compare the results manually.

Does the tool modify my firewall configuration files?

No, the tool only analyzes and provides recommendations. It does not modify or rewrite your original configuration files. You receive a detailed report with suggestions to implement manually.
