What Is ISE?

A product called Identity Services Engine (ISE) is an identity and access control policy platform that can validate that a computer meets the requirements of a company’s policy related to virus definition files, service pack levels, and so on before allowing the device on the network. This solution leverages many AAA-like (authentication, authorization, and accounting) features, but is not a 100 percent replacement for ACS. For the near future, customers who want the features of ISE will likely use ACS for the authentication and authorization components and use ISE (in addition) for the posturing and policy-compliance checking for hosts.
