Explanation
Cisco ISE benefits our customers by providing network access control and helping them stop and contain real-time threats. Network access control is the ability to enforce policies on who and what can access the network, based on the identity and context of users, devices, and applications. Cisco ISE allows customers to authenticate, authorize, and audit network access, as well as to segment and isolate network traffic based on security and compliance requirements. Cisco ISE also helps customers stop and contain real-time threats by leveraging intel from across the network and security ecosystem, and by automating threat response actions.
Cisco ISE can integrate with various security solutions, such as Cisco Stealthwatch, Cisco Firepower, and Cisco Umbrella, to detect and mitigate attacks on the network quickly and effectively. References:
