FortiClient - Application Firewall - unknown applications

Hi there,

i've just installed the FortiClient v6.4.2 and wanted to test all features supported for windows clients.

Curiously, the application firewall modul seems not to work correct.

The application firewall is only detecting "unknown applications". Even for well known applications such as "teams.exe", "outlook16.exe" and "firefox.exe".

I've uploaded an screenshot of the application firewall events shown in the EMS (https://ibb.co/GC9BKPM). Am I anything missing?

Thanks in advance.

Kind regards,

Dominik
