Radiator AAA server software has been available on the market since mid-1990s, when different ISPs needed a reliable and flexible RADIUS server for their authentication, accounting, and authorisation needs. Originally, Radiator was developed by Australian-based Open System Consultants PTY Ltd until 2013, when the company was merged with Finnish Arch Red Oy. Together, those two companies are now Radiator Software.

Being on the market for around 20 years, Radiator has been developed extensively, and still is today. With customers in over 180 countries globally, and used extensively by telcos, CSPs, enterprises, public organisations, the story of Radiator goes on.
