Looking for a tool that can perform automated firewall audits across multiple devices, platforms, and sites?
anyone know of anything?
Tufin. Also Tufin. You might want to consider Tufin, as well.
The longer version is... Tufin has some great built-in auditing features, all available in the base product, SecureTrack. Works with firewalls of nearly all vendors - all the majors, for sure - and can also audit security on IOS routers and switches. I love it, I does.
Just started using Firemon. Very feature rich and intuitive.
