In the film Marathon Man, Laurence Olivier repeatedly asks Dustin Hoffman, "Is it safe?" to proceed with his plans. Corporations ask the same question every time a user--especially a mobile user--logs in to the corporate network.

In the often confusing and still immature network access control market, ForeScout Technologies' CounterACT hits the sweet spot, providing flexible, policy-based security with minimal impact on infrastructure and users.

This is no mean feat, as corporations try to make sense of competing solutions--Cisco's NAC, Microsoft's NAP, Trusted Computing Group's standards-based Trusted Network Connect and a fistful of third-party products.

CounterACT is innovative technology that solves an important problem, from a company that earned credibility with its flagship product, ActiveScout, which brought a fresh and effective approach to network intrusion prevention.
