Designing a VPN Environment

VPN tunnels introduce an additional layer of complexity to the security aspects of your network. When you set up a VPN environment, you are expanding your security perimeter to vulnerable settings such as hotel rooms, airports, and employees' homes. And your company's network security is only as strong as its weakest link.

Another primary concern when deploying VPNs, which must often be balanced with security concerns, is performance. Many of the most secure options available for VPNs come at a high performance cost.
