Good evening,
I have a problem with my users and i cannot find any way to stop it.
So the problem is this:
I have blocked everything (anonymizers, remote access and other similar services)
I have only the port 80 accessible from users and only TCP
The problem is that they pass my firewall using VPN Solution like OpenVPN by enabling the HTTP Proxy on VPN app.
Using an HTTP "Tunneling" to another system they open any url.
Is there any way to Cut these services? (without using the bad way)
