Cloud-Native RADIUS

Q: Is Portnox Cloud RADIUS compatible with my existing network hardware and infrastructure?

Yes. Portnox Cloud RADIUS is vendor-agnostic, meaning it supports virtually any 802.1X-capable switch, wireless controller, or access point, including those from Cisco, Aruba, Fortinet, Ubiquiti, and others. There is no need to replace existing hardware. In fact, many Portnox customers migrate from legacy RADIUS/NAC setups to cloud-native RADIUS without touching physical infrastructure.Additionally, Portnox offers easy-to-deploy RADIUS proxy virtual appliances for environments that need to securely forward authentication requests from internal networks to the cloud.

Q: How does Portnox handle certificate-based authentication (EAP-TLS)? Do I still need a separate PKI?

Portnox simplifies EAP-TLS by offering built-in certificate management as part of its Device Identity Management module. This means: You can issue, renew, and revoke client certificates directly from the cloud dashboard. No need to manage a complex, on-prem PKI infrastructure. Works across Windows, macOS, and mobile devices with guided or silent enrollment options. Supports compliance enforcement by tying certificate validity to device posture and directory membership. This streamlines zero trust access initiatives while significantly reducing the operational burden associated with certificate-based authentication.

Q: What kind of logging and visibility does Portnox Cloud RADIUS provide?

Portnox provides rich logging and real-time visibility into every authentication event:Detailed logs for successful and failed authentications, including user/device identity, IP, MAC address, RADIUS attributes, and reasons for denial.Syslog export and SIEM integration, making it easy to plug into tools like Splunk, Sumo Logic, or Microsoft Sentinel.Dashboards to monitor network access trends, failed login attempts, and potential misconfigurations or threats.Compliance reports for audits, user activity, and device inventory tied to identity.This level of visibility is often missing or hard to implement in traditional RADIUS solutions.

FAQs

How does Portnox’s cloud-native RADIUS differ from traditional on-prem RADIUS solutions like FreeRADIUS or Microsoft NPS?

Portnox’s cloud-native RADIUS is a fully managed, globally distributed service that eliminates the need for physical servers, manual configuration, or on-site maintenance. Unlike legacy systems like FreeRADIUS or NPS, which require constant patching, updates, and high availability design on-premises, Portnox offers:

Redundant, scalable infrastructure hosted in the cloud (Azure).
Global reach with low-latency authentication from anywhere.
Automatic software updates and built-in failover for high availability.
Modern authentication integrations, including SAML, Entra ID, Okta, and certificate-based access.

This modern approach frees up IT resources, reduces overhead, and enhances security posture through constant compliance and hardened cloud environments.
