FreeRADIUS
The world's leading RADIUS server — fast, feature-rich, modular, scalable.

FreeRADIUS is the most widely deployed open-source RADIUS server in the world, used by major ISPs, telecom companies, enterprises, and educational institutions to authenticate hundreds of millions of users daily. It implements the RADIUS protocol for AAA (Authentication, Authorization, and Accounting) and supports additional protocols like DHCP and ARP. The project is maintained by InkBridge Networks, which offers commercial support and consulting services.
FreeRADIUS runs as a multi-protocol policy server implementing RADIUS and related protocols, integrating with directories, databases, and identity providers to authenticate and account for user sessions.
