FreeRADIUS

FreeRADIUS is completely scalable and supports both large and small user databases. Because it doesn't take up a lot of server resources, FreeRADIUS is well-suited for organizations with small budgets (it's in the name!) and limited networking hardware. While there is a port of it for Windows, FreeRADIUS is native to Linux so that would be a limitation for many companies who don't use it.

• FreeRADIUS is easy to configure
• It is fast a lightweight footprint on the server
• FreeRADIUS works universally with other systems that support radius authentication

• FreeRADIUS requires a 3rd party interface to make it easier to access (we use Daloradius) - it would nice if it was built in.
• Installation and configuration are pretty easy and straightforward but does require connecting to a database which can be cumbersome.

• We previously used Microsoft Network Policy Server for our RADIUS authentication which works ok but was pretty clunky and requires Windows Server. Switching to FreeRADIUS brought our cost down to zero.
• Because FreeRADIUS works natively in Linux it's easy to setup and works with all distros.
• FreeRADIUS allows us to have user authentication for wifi which is much more secure than a simple shared password solution.
