Blocking VPN Softwares in mobile device

Hello,

Greetings!

To block VPN applications, you can use Web Filter and Application Security Profiles.

"Proxy Avoidance" category in Web Filter and "Proxy" category in Application Control.

Some applications may require Deep Inspection Certificate to be used in Firewall Policy as SSL Inspection. For such cases, that Deep Inspection Certificate should be downloaded and installed on users' devices.
