Yes, its possible, but you have to block in application too. some VPN can bypass like thunder vpn. so once you implement you have to test the connection.

i have liked your presentation please keep on bring such. however, this vpn "Proton" still by bypasses the firewall. ill be great fully if you can share how to block it
@@mohsinalibhatti7072 Of-course it will affect other application, If you are using OPENVPN to connect your company branch etc. or any other UDP protocol, it will not work if you close all the UDP port, so better option is add only particular UDP port depends upon your requirements.

No I already tested all vpn, if you disable UDP protocol then, you can block almost all vpn, I already tested. And successfully blocked.
i have tried the same but still users are able to connect to super vpn , i believe app is using udp protocol
yes, ofcourse super VPN and most the VPN use UDP protocol for best performance. so you have to disable or remove UDP protocol.
