Cisco Identity Services Engine (ISE), is an identity and access control policy platform enables enterprises to enforce compliance, enhance infrastructure security, and streamline their user network access operations. Cisco ISE allows enterprises to gather real-time contextual information from networks, users, and devices to facilitate network user access operations and to make proactive governance decisions by tying identity to various network elements including access switches, wireless LAN controllers (WLCs), virtual private network (VPN) gateways, and data center switches.
