Knock, knock. Who's there?

Portnox's RADIUS service can help you answer just that and more. Stare through the proverbial peep hole and see who’s requesting access to your network, as well as the access layer they’re using, their location, device type, and more.

Our cloud-native RADIUS is provided through a cloud-based cluster of fully redundant RADIUS servers and is used for authentication of users accessing the enterprise. Integrate with your existing identity provider, use ours, or set up passwordless authentication with ease.

No connection? No problem.

Internet outages can affect your colleagues' ability to work, duh. But have no fear! To solve this issue, Portnox offers a local RADIUS instance that works overtime - when there is connectivity with the cloud, it acts as a proxy in a chain, forwarding communications to and from the cloud RADIUS service.

If our cloud RADIUS authentication service cannot connect to the cloud, the local RADIUS assumes the role of the cloud RADIUS until connectivity is restored!

Let us upgrade you

Sure, Beyonce can “upgrade ya,” but here at Portnox we can offer you network authentication and a whole lot more. Take your network security up a notch with our cloud-native zero trust NAC for full access control coverage.

With Portnox zero trust NAC, gain real-time visibility of endpoints trying to connect to your network, plus additional context such as their location, device type, and requested access layer for authentication. This applies to managed company devices, BYOD and IoT / OT alike, no matter if they're authenticating via wired ports, Wi-Fi or VPN.
