What is Cisco ISE? Cisco Identity Services Engine (ISE) is a comprehensive identity-based network access control and policy enforcement system. It allows organizations to securely manage access to network resources by enforcing policies for users and devices. ISE provides authentication, authorization, and accounting (AAA) services, allowing administrators to define and enforce security policies based on user identity and the context of their devices. Key features of Cisco ISE include: Centralized Policy Management: ISE provides a centralized platform for creating, managing, and enforcing security policies across the network. Network Access Control (NAC): It enables organizations to control access to the network based on user identity, device type, location, and other contextual factors. BYOD (Bring Your Own Device) Support: ISE allows organizations to securely onboard and manage devices owned by employees, contractors, and guests, ensuring compliance with security policies. Gues
