What We Secure: Access Control Apps
RADIUS
From VPN to network devices, SurePassID Universal MFA enables secure access with RADIUS multi-factor authentication.

Lock down RADIUS clients – including VPN – with SurePassID
SurePassID Universal MFA can secure any RADIUS-compliant system such as Microsoft Universal Access Gateway, VPN routers/devices, Citrix applications, Wi-Fi access points, FreeRADIUS on Linux distros, and more. We support key features such as:
- Challenge Response – The server “challenges” the user for any of their registered assigned credentials. Most challenges will be to provide a One Time Password (OTP) after successfully entering a valid username and password. (Some RADIUS devices only support single-factor authentication, in which case two-factor authentication (2FA) is added by appending the OTP to the user’s password.)
- Proxy Server Chaining – In RADIUS authentication, there are often multiple RADIUS servers as part of the authentication process.
- nFactor Authentication Framework – Enables organizations to define dynamic authentication methods at the time of authentication on a user by user basis.
But SurePassID’s strengths don’t end there. As a highly extensible solution, our platform encompasses on-premise, cloud, and hybrid deployment architectures. No matter what your universe of RADIUS clients and remote access gateways looks like, SurePassID can secure it with RADIUS multi-factor authentication.

“We selected SurePassID due to their performance and professionalism during a multiple vendor competition for a two-factor authentication solution for our VPN and Outlook Web Access users. They listened to what was important to us, provided a solution summary reflecting what we wanted and, most important of all, delivered what they promised in the most expedient and efficient manner. We were up and running and trained in about two hours. Very impressive.”

Customer: Accounting firm with 100 users
Problem: Sudden need for additional VPN/MFA licenses due to COVID-19 work-from-home requirements. Existing Forticlient solution was too expensive.
Solution: SurePassID locked down their VPN, reused their existing FortiTokens, and provided push authentication to users – all for a fraction of the cost.
