## About FreeRADIUS
FreeRADIUS is used daily by 100 million people to access the Internet. FreeRADIUS is responsible for authenticating a third of all users on the Internet.There are a small percentage of sites have over 10,000,000 (that's 10 MILLION) users. When we add up all of the sites, the total comes to about 100,000,000 users who are authenticated via FreeRADIUS. And that number includes only the sites that filled out the survey! In total it is estimated that FreeRADIUS is responsible for authenticating more than ⅓ of users on the internet. Other users are split between Cisco ACS and Microsoft IAS (each with an equal share); and all the other RADIUS servers combined.
