Securent and its vision of providing granular application entitlement security via its XACML architecture was just validated big time by the announcement that it was being acquired by Cisco.  This is one of the most successful security exits in recent history based on several financial metrics.  Securent and XACML provide true ROI benefits by allowing an enterprise to enforce critical business policies within applications without rewriting mountains of code or creating loopholes.  You will all be using it soon, so go learn more about XACML.  I will pat myself gently on the back for picking this one and joining their advisory board.
