Due to the limitations of the original FreeRADIUS, ported the server to work on the Windows platform. Just like any other software, the developers can stall development anytime they want. This is the case for, which only offers builds up to version 1.1.7, which is two years old. is only good for smaller businesses looking to deploy RADIUS on an existing Windows machine, and who do not care about support.

Available for Windows only.


The easiest to configure and use of the no-cost RADIUS servers on Windows, TekRadius provides a good option for companies who want to set up a RADIUS server on their existing backend infrastructure which runs on Windows XP/Vista.

TekRadius is stable and easy to use. The key features that I love about TekRadius include:

  • Ability to expire users
  • Ability to check users' credit limits
  • A nice interface to browse accounting records

Available for Windows only.


RADIUS GNU works exactly the same as FreeRADIUS above, except that it supports a wider range of authentication schemes, including:

  • System Database: User credentials are stored in /etc/passwd
  • Internal Database: User credentials are stored in the internal RADIUS database
  • SQL authentication: User credentials are stored in a standard SQL database
  • PAM (Pluggable Authentication Service) authentication: Applications are not required to be re-written to support different authentication schemes. See this documentation on Linux PAM for more information.

Other than the above authentication schemes, there's no major difference with this RADIUS server software.

Available for Linux/Unix only.
