What Our Clients Say

Once your GreenRADIUS server is up and running, that’s what it keeps doing, running without any issues.

Jim Bugbee

IT Director, Rusk County

The migration from YubiRADIUS to GreenRADIUS was very easy and well-documented. The change also allowed us to add the OATH Module to give our end users more authentication options. Green Rocket Security has been one of our best vendors to work with, and we would recommend them to anyone looking to implement two-factor authentication.
