Web application firewall

Web application firewall (WAF) profiles can detect and block known web application attacks. You can configure WAF profiles to use signatures and constraints to examine web traffic. You can also enforce an HTTP method policy, which controls the HTTP method that matches the specified pattern.

You can customize the default profile, or you can create your own profile to apply access rules and HTTP protocol constraints to traffic. You can apply WAF profiles to firewall policies when the inspection mode is set to proxy-based.
