The two major types of Virtual Private Networks (VPNs) are IPSec and SSL. IPSec VPNs can be useful if you have a small and tightly controlled group of remote users, but enterprises today are a lot more spread out. It is difficult to have that kind of access with an IPSec VPN, and the remote mountaintop scenario is possible only with an SSL VPN. The simple reason is "clientless connectivity." The IPSec VPN requires a fat client to be installed on each remote workstation, something that is only doable when remote workers connect from the same workstation every time, and that workstation can be physically accessed by your IT staff.
