Radiator RADIUS Server, delivered and supported in the UK.
Radiator is the RADIUS, RadSec, TACACS+ and Diameter authentication server behind universities, public bodies, enterprises and operators. Level9 Networks supplies the licences, designs the deployment, migrates you onto it and supports it from the UK.
What Radiator is
An authentication server you can read, extend and trust in the critical path.
Radiator Software Oy first released Radiator in 1998 and has developed it continuously since; the vendor reports customers in more than 180 countries, from tier-one operators to small ISPs and universities. Radiator 4 licences ship with the full source code, and the Radiator 10 generation adds a dashboard, REST API and container images. It speaks every protocol a modern network uses, connects to every identity source you are likely to have, and expresses policy precisely rather than through a wizard.
It is used for secure Wi-Fi, device administration, eduroam and govroam, guest access, and carrier-scale subscriber authentication for broadband, Wi-Fi offload and voice over Wi-Fi.

Ask about operator use casesThe Radiator family
Two servers, the operator packs, one hosted option.
- 01 Radiator AAA Server
Radiator AAA Server is the long-established Radiator 4 product line, a RADIUS, RadSec, TACACS+ and Diameter-gateway server supplied with full source code, more than sixty authentication methods and connectors to the directories, databases, identity and multi-factor services most organisations already run.
- 02 Radiator Policy Server
Radiator Policy Server is the Radiator 10 enterprise server. Built on a new high-performance core, it adds a web dashboard, log viewer, configuration templates and editor, a REST API and Lua scripting to the Radiator RADIUS and TACACS+ engine, for teams that want modern operations without giving up control.
- 03 Radiator Core
Radiator Core is the Radiator 10 server for operators. It runs the same high-performance engine as Radiator Policy Server, packaged for ISPs and communication service providers with IP pool allocation towards broadband gateways, a dashboard, a REST API, Lua scripting and official container images.
- 04 Radiator Service Provider Pack
The Service Provider Pack is the Radiator bundle for ISPs and operators. It combines Radiator AAA Server with a Diameter server, Diameter relay and equipment identity register functions under a network-wide licence for unlimited Radiator instances, priced on users rather than servers.
- 05 Radiator SIM Pack
The SIM Pack adds SIM-based authentication and the full 3GPP AAA server role to Radiator: EAP-SIM, EAP-AKA and EAP-AKA' with the Diameter and MAP interfaces to the HSS and HLR, and IMSI privacy, so operators can authenticate subscribers on Wi-Fi exactly as they do on the mobile network.
- 06 Policy and Charging Pack, GBA/BSF Pack, RadiatorDB and Auth.fi
Diameter Gx, Gy, Gz and Rx components bridging RADIUS networks to charging and policy systems, GBA bootstrapping for VoLTE and RCS services, the Radiator 10 multimaster document database, and Radiator Software's hosted RADIUS service for Wi-Fi, wired and VPN access. Ask us for details.
