NAC COMPANIES CHANGING

By D.E. Levine

Even as the need for security grows, it's a sign of the time that network access control (NAC) companies are either going out of business, being bought by other companies or changing directions.

NAC was introduced in 2003 and now one of the business pioneers, ConSentry, has gone out of business. ConSentry began by selling NAC gear embedded in intelligent switches.

Although it changed it's marketing strategy to reflect other functionality, the company was in a battle against the major switching vendors and ConSentry lost the battle.
