WallParse Firewall Audit Tool – Firewall Config Analyzer

WallParse Firewall Audit Tool is a firewall audit tool for Cisco ASA firewalls. It parses configuration files from Cisco ASA and there is also experimental support for Fortigate firewall CSV export files. The intended use is to allow firewall auditors to audit firewalls without having login credentials for the firewall.

The configuration file is exported (for example using “show running-config”) and is imported into WallParse.
