Network Access Control (NAC) solutions has arrived, with the support of some of the largest vendors in the IT/networking world, its own consortium, the excitement of users at organizations of all types and sizes, real available solutions, and significant revenue generated. Secure Sockets Layer Virtual Private Networks (SSL VPNs) have a central enforcement role to play in NAC architectures, according to leading analyst Jeff Wilson in this Infonetics Research report entitled, "Enforcing Network Access Control: Market Outlook and Worldwide Forecast".

SSL VPNs are positioning against other NAC solutions as a pervasive access control solution, to be used regardless of employee location, whether on the LAN, at the airport, or inside a customer's network. While remote access will remain the primary driver for SSL VPNs overall, companies who buy SSL VPNs initially for remote access will quickly turn them inward and use them for NAC-like solutions.
