How endpoint security works
If you are interested in using VPNs nowadays, you should also be interested in using endpoint security.
This software sits on remote machines that are trying to access the VPN and checks whether the device meets security policies for the company that set up the VPN. If not, access is denied.

Other vendors would say the machine has failed and to contact a network administrator for further instructions.
