Two days. Two formats. One global community. Registration is now open for the second annual RADIUS Conference—the only event in the world dedicated to the protocol securing hundreds of millions of daily user connections.
Radiator Software and InkBridge Networks are co–hosting the the second annual RADIUS Conference, the only global event dedicated to the authentication protocol securing hundreds of millions of daily user connections across ISPs, enterprises, educational institutions, and critical infrastructure worldwide.
Building on the success of the inaugural 2025 conference in Tampere, Finland, RADIUS Conference 2026 returns in an upgraded two-part format:
- Workshop — Monday, June 8, 2026, at Finlandia Hall in Helsinki, Finland, as an official side event of TNC26, the premier European research and education networking conference hosted by GÉANT.
- Virtual Speaker Series — Monday, June 15, 2026, streamed globally and free to attend, featuring a full day of expert sessions across four tracks: ISP, Enterprise, General RADIUS, and Educational/Federated Identity.
Both events are open for registration today at radiusconference.org.
Featured Speakers
The 2026 program features practitioners and standards-setters from across the global RADIUS community. Confirmed marquee speakers include:
Karri Huhtanen — CTO and Founder of Radiator Software Oy, the Finnish company behind the Radiator commercial RADIUS server used by carriers and enterprises worldwide. Co-organiser of the conference and a long-standing voice in the European RADIUS community. Karri will present “Expand Your Awareness RADIUS – Using RADIUS to improve network situational awareness” to discuss how most network administrators view RADIUS primarily as a gatekeeper—the “Yes/No” checkpoint for network entry. However, beneath the surface of simple authentication lies a massive, often ignored stream of real-time telemetry. Every access request and accounting packet contains critical metadata about the “who, what, where, and when” of your environment.
Alan DeKok — Founder of the FreeRADIUS Project and CEO of InkBridge Networks. Conference host and speaker, DeKok has led the open-source FreeRADIUS project for more than two decades and is a contributor to RADIUS standards work at the IETF.
Mark Grayson – Cisco Fellow in the Global Technology and Standardization Group, where he holds broad responsibility for supporting Cisco’s 5G/6G strategy. He has been granted over 200 patents in mobile communications, chairs the WBA’s OpenRoaming program, and co-chairs the O-RAN Alliance’s Fronthaul Working Group. Mark will present “Developing a Resilient Infrastructure with Mission Critical and Emergency Services.” outlining a framework for how Wi-Fi, Passpoint, and OpenRoaming can facilitate and sustain emergency calling and priority communications between the public, first responders, public safety organizations, and emergency services.
Bryan Lechner — Director of Product Line Management, NAC and SSE, at Hewlett Packard Enterprise. With more than 25 years in commercial network security, Lechner will present “RADIUS is Dead, Long Live RADIUS,” a candid look at how the protocol is evolving to meet customer demands in the era of cloud, quantum computing, and dynamic network security.
Eva Santos — Service Delivery Engineer and Certified Wireless Network Expert (CWNE), with prior product and consulting roles at Cisco. Santos will deliver “The Importance of RadSec post-BlastRADIUS,” examining why the most important RADIUS upgrade in a decade remains chronically under-deployed — and what to do about it.
Additional speakers from Internet2, the eduroam community, and global service providers will be announced in the coming weeks. The full program will be published at radiusconference.org.
