Network Endpoint Assessment (NEA) Working Group hopes to complete a requirements document during the first half of 2007. The NEA group will lead to proposals for an industry-wide protocol for communications between a client device and a security policy server.

Cisco and Microsoft partnered earlier this year to harmonize Cisco Network Access Control and Microsoft Network Access Protection.”]
