Adds Multi-Factor Authentication to an Existing RADIUS Server
The RADIUS Gateway enables existing RADIUS Servers to be supplemented with multiple factor authentication. Any LDAP attributes or a database on the SignOn Proxy can be used for MFA management.
Modernize Network Security Without Infrastructure Changes
Your network infrastructure requires stronger authentication, but replacing your existing RADIUS servers isn't practical or cost-effective.
The RADIUS MFA Challenge
- Limited MFA Support: Existing RADIUS servers often lack modern multi-factor authentication capabilities or only support basic token methods.
- Expensive Replacement: Replacing existing RADIUS infrastructure requires significant investment and complex migration projects.
- Operational Risk: Changes to critical network authentication infrastructure introduce downtime and compatibility risks.
The Passthrough MFA Advantage
- Preserve Your Investment: Keep your existing RADIUS servers and backend systems unchanged while adding MFA capabilities.
- Modern MFA Methods: Add FIDO2, Smart Cards, TOTP/HOTP, and COTP push notifications to any RADIUS authentication flow.
- Transparent Integration: Network devices and applications see no changes - the MFA layer is completely transparent to existing infrastructure.
Smart RADIUS Proxy with MFA Layer
The SignOn Proxy sits between your network devices and existing RADIUS server, intercepting authentication requests to add MFA verification while forwarding all other requests unchanged.
How It Works:
- Selective Interception: Only authentication (Access-Request) packets are intercepted for MFA processing - all other RADIUS traffic flows directly to your existing server.
- MFA Enhancement: Adds second-factor verification using FIDO2, Smart Cards, TOTP, or COTP before forwarding to your RADIUS backend.
- Seamless Integration: Network devices require no configuration changes - simply point them to the SignOn Proxy instead of the original RADIUS server.
