You can’t block VPNs without blocking the entire internet. You can block known VPN services, but you can’t prevent people from hosting their own.
Some known VPN protocols could be blocked, using introspection tools. However, this would just render corporate VPNs useless. VPN traffic is just bytes, and so is WebSockets. Good luck figuring out whether my HTTPS traffic is legitimate internet traffic, or masked VPN traffic.
