The Forefront Integration Kit with NAP (Network Access Protection) has been released. This was previously a beta offering from the Solution Accelerator team.
Other Anti-Malware vendors such as Symantec, McAfee, & Trend all charge extra for the ability to integrate with NAC or NAP. In Level A or B pricing customers, there’s been much as $13/user on top of what is already being charged for their anti-virus software. Even worse, the security vendors that sell appliances to do NAC often quote as much as $30 *per port* to do in-line Network Admission Control.
Microsoft includes full NAP/NAC support with Forefront Client Security at no additional charge. Any customer with Windows Server 2008 also owns NAP licensing which is built into Windows Vista & Windows XP Service Pack 3.
