Secure Computing Corporation, an enterprise gateway security company, announced it has signed a definitive agreement to acquire Securify, a provider of identity-based monitoring solutions, for approximately $15 million plus an earn-out of up to $5 million. The acquisition is expected to close in the fourth calendar quarter of 2008. Securify provides a solution for monitoring and controlling user access to applications within changing networks. Securify’s solution identifies and alerts organizations to out-of-policy behavior in real time, whether accidental or intentional. Securify can also initiate automated blocking actions in routers, switches, or in the case of Secure Computing, in firewalls.
