Endpoint Windows login authentication for LAN users

Hi Folks,

I need to know how we can get internal corporate user windows logon authenticated via VIP. Do we have to deploy a VPN client on each endpoint which will add up hidden cost to the solution for procuring a VPN solution or is there any RSA type endpoint agent which diverts all logon (remote and local) to VIP EGW server??

Does VIP have some kind of agent/client for servers authentication as well???

Regards,

Atif
