Securent has been the leader in Enterprise Entitlements Management. They have tried to solve the access control/authorization maze to a large extent. Even though I am not familiar with their patented technology, I have met Sekhar and Anil T at the Burton XACML Interoperability in June 07.
I want to congratulate Rajiv, Sekhar and Anil on the acquisition by Cisco as publicized in Cisco News.
Gerry Gabel from Burton has written a nice piece about this here.
