Foundry Networks, McAfee, Symantec, Avenda Systems and a start-up named Napera Networks have stated that their security platforms can plug into a NAP deployment. NAP clients on Windows computers send health checks; the Microsoft Network Policy Server in Server 2008 evaluates those health checks and, based on the results, instructs the Foundry switches to enforce access restrictions. McAfee has plans to support NAP starting in March, when it releases a new version of its Network Access Control software.”]
