privador.com - solutions - case studies - vpn - no internet access I'm reading up on VPNs and security in preparation for a presentation I'm giving in March at the Telecom Supply Chain conference in Scottsdale, AZ. This site describes an almost totally secure implementation. Unfortunately, to achieve this security, you need to remove all Internet access points. Not generally a feasible solution. A really good overview of VPN and security technology is a white paper by OpenReach. Very readable and simple enough for most folks to be able to follow.
