Good Morning.
I wanted to know how one would block users on VPNs, VPN Anonymizers, and Anonymizers from being able to log onto my network via Cisco Anyconnect. I'm concerned that some WFH users have moved outside of the USA and are using them to cover their tracks. My thought is that they're using VPNs via their routers, phones, and other devices to cover their tracks.
I know a little bit about networking, so I was curious if there was any documentation on the issue. I've reached a dead end and could use a few ideas.
