Information
Set Applications and File Types fields to any in WildFire file blocking profiles. With a WildFire license, seven file types are supported, while only PE (Portable Executable) files are supported without a license. For web traffic, the action "continue-and-forward" can be selected. This still forwards the file to the Wildfire service, but also presents the end user with a confirmation message before they receive the file.
If there is a "continue-and-forward" rule, there should still be an "any traffic / any application / forward" rule after that in the list.
Rationale:
Selecting 'Any' application and file type ensures WildFire is analyzing as many files as possible.
Solution
Navigate to Objects > Security Profiles > File Blocking.
Set a rule so that Applications is set to any, File Type is set to any, and Action is set to forward.
Default Value:
Not Configured
