RADIUS Insights

What is RADIUS?

RADIUS (Remote Authentication Dial-In User Service) is a networking protocol that provides centralized Authentication, Authorization, and Accounting (AAA) management for users who connect to a network service. It's commonly used by ISPs, enterprises, and educational institutions to manage network access and security policies.
