Good afternoon

I'm hoping someone might have an answer for me. I'm trying to see if there is a way to block any traffic coming from a Student IPad or Laptop when they try and use a VPN Client or more so a VPN Add-On in Firefox or Chrome. I'm hoping there is a way on the firewall that it can detect that the client is using some type of VPN and it will block that traffic. Thanks for any help in this issue.
