Executive Summary (This is a document excerpt)

Forrester predicts that 2006 will be a big year for network access control (NAC), also known as network quarantine, which provides a framework for proactive network security. Just how big? In January 2006, Forrester surveyed 149 technology decision-makers at North American companies and found more than one-third already plan to adopt NAC this year. Organizations want NAC for increased security across all access technologies — wired, wireless, and remote-access alike. Companies with no plans to deploy NAC in 2006 feel that cost and manageability are the primary obstacles. However, those same companies with no NAC adoption plans are still looking to put the NAC building blocks in place; 49% are likely to upgrade their switching hardware to port-based authentication-capable switches in 2006.
