Research: 60 percent of enterprises to deploy NAC by 2008.

"There is massive potential for NAC," said Jeff Wilson, principal analyst at Infonetics Research and author of the report. "The number one driver for deploying NAC is protecting corporate resources from unauthorised users. This is really the strong point of NAC, and the most commonly listed benefit of rolling out NAC solutions."

According to his research, small and medium organisations are also buying into NAC. He expects about half of these smaller businesses to deploy NAC by 2008.

Wilson's study also found that firms are investing heavily in security at the gateway, particularly anti-virus, anti-spyware and spam filtering products and services.

According to his figures, 90 percent of the organisations in his study have already invested in gateway anti-virus, and 66% will spend more money on it next year. Additionally, say they will buy and deploy a standalone single-function content security gateway product to rapidly address a new threat.
