WHY A RADIUS CONFERENCE, WHY NOW

First published in 1991, RADIUS (Remote Authentication Dial-In User Service) has quietly become one of the most widely deployed protocols on the internet. It underpins eduroam, the global roaming federation connecting more than 10,000 research and education institutions. It authenticates carrier-grade subscriber networks at major ISPs. It secures enterprise Wi-Fi, VPNs, and zero-trust access deployments around the world.

Yet despite its scale, RADIUS has lacked a dedicated forum, a place where the people who write the standards, build the implementations, and operate the world's largest deployments can meet, compare notes, and shape the protocol's future. The 2024 disclosure of the BlastRADIUS vulnerability (https://www.inkbridgenetworks.com/blastradius) made clear what was at stake. The 2025 conference made clear that the community was ready.

QUOTES

"The RADIUS community has been hungry for a dedicated space to compare notes, debate the future, and learn from each other. Joining forces with TNC26 takes that conversation to exactly the right audience — the networks and institutions that depend on this protocol every single day."
