Portnox delivers a cloud-native RADIUS server that centralizes RADIUS authentication, authorization, and accounting (AAA) across wired, wireless, and VPN environments—without hardware, agents, or ongoing maintenance.
Deploy in minutes, enforce consistent access policies everywhere, and replace legacy RADIUS servers with a platform designed for modern networks, distributed users, and zero trust architectures.
The RADIUS protocol (Remote Authentication Dial-In User Service) has been the foundation of network authentication for decades. Its continued adoption is intentional: RADIUS is secure, proven, and widely supported by network access devices such as switches, wireless access points, firewalls, and VPN gateways. What has changed is the environment RADIUS must support.
Traditional, on-prem RADIUS authentication servers struggle with:
With Portnox’s RADIUS server, you get all the advantages of the gold standard of network authentication since the dawn of the internet, plus all the advantages of a modern cloud-native solution. No provisioning extra hardware, no patches, no maintenance – your IT admins and your users will thank you.
Staying ahead in IT means strengthening cybersecurity—and zero trust architectures now lead the charge. But let’s face it: embracing zero trust can feel daunting. With so many tools and complexities, it’s easy to lose your way.
To understand how organizations navigate zero trust, Portnox teamed up with TechTarget. We surveyed hundreds of IT and cybersecurity professionals across North America. Discover the insights we uncovered in our Trends in Zero Trust report.
A RADIUS server acts as a centralized authentication system that manages authentication, authorization, and accounting for network access. It validates user and device identities, enforces access policies, and logs activity across wired, wireless, and VPN environments.
A cloud RADIUS server eliminates on-prem infrastructure by delivering authentication as a managed service. It provides built-in high availability, automatic updates, and elastic scalability, reducing operational overhead while maintaining compatibility with existing network access devices.
RADIUS authentication supports 802.1X by validating credentials or certificates forwarded by network access devices. The RADIUS server evaluates identity using EAP methods and returns authorization decisions that determine whether users or devices are granted network access.
The RADIUS protocol enables centralized authentication and authorization across enterprise networks. It ensures consistent access control, records detailed accounting logs, and supports security policies that improve visibility, auditability, and enforcement at every network entry point.
Certificate-based RADIUS authentication replaces passwords with cryptographic certificates using EAP-TLS. This approach reduces phishing and credential theft risks, strengthens identity assurance, and supports zero trust access models through strong, device-bound authentication.
Yes. Portnox Cloud RADIUS is designed to fully replace traditional on-prem radius servers, eliminating hardware, operating system maintenance, and manual scaling while improving resilience and operational efficiency.
Portnox Cloud RADIUS supports industry-standard authentication methods used by enterprise radius servers, including certificate-based authentication, identity-driven access, and policy-based authorization—enabling secure access without sacrificing user experience.
