What Is Cloud RADIUS?
Network authentication without the server room
RADIUS (Remote Authentication Dial-In User Service) is the protocol that decides who gets on your network. Every time someone connects to WiFi with their own credentials instead of a shared password, a RADIUS server is doing the work behind the scenes.
Traditionally, that meant running your own server - FreeRADIUS on Linux, Microsoft NPS on Windows Server, or Cisco ISE for the enterprise crowd. All of them require hardware, patching, certificate management, and someone who knows how to keep them running.
A cloud RADIUS server does the same job, but IronWiFi runs the infrastructure for you. You point your access points at our servers, connect your identity provider, and you're done. We handle the uptime, the updates, and the global distribution.
Think of it as RADIUS-as-a-Service: all the authentication power, none of the operational burden.
Fully Managed
No servers to install, patch, or monitor. We handle all of it.
Globally Distributed
6 regions worldwide for low-latency authentication everywhere.
Standards-Based
RFC 2865 compliant. Works with any RADIUS-capable hardware.
Always Available
99.9% uptime SLA with automatic failover between regions.
How Does Cloud RADIUS Work?
Four steps between your user and secure network access
The Authentication Flow
When someone connects to your network, here is what happens behind the scenes - in milliseconds:
Device Connects
A user or device joins your WiFi and presents credentials (username/password) or a certificate to the access point.
Access Point Forwards to IronWiFi
Your access point sends the RADIUS request to IronWiFi's nearest cloud server. No on-premise RADIUS needed.
Identity Verification
IronWiFi checks the credentials against your identity provider - Azure AD, Google Workspace, Okta, or your LDAP directory.
Access Granted with Policies
The user gets network access with the right VLAN, bandwidth limits, and access policies applied automatically.
Why This Architecture Matters
Zero On-Prem Footprint
No servers in your closet. No VMs to maintain. Just point your APs at our cloud.
Automatic Failover
If one region has an issue, your traffic routes to the nearest healthy one instantly.
End-to-End Encryption
RADIUS traffic encrypted via RadSec (RADIUS over TLS) between your AP and our cloud.
Full Audit Trail
Every authentication attempt logged with timestamps, device info, and results.

Multi-Site Deployments
One cloud RADIUS for all your locations. Consistent authentication policies, centralized management, local RADIUS proximity.
"We migrated from FreeRADIUS across three data centers to IronWiFi in a single afternoon. The Azure AD integration worked immediately, and we eliminated two servers and 20 hours of monthly maintenance. It was the easiest infrastructure decision we made all year."

Cloud RADIUS: Frequently Asked Questions
What IT teams want to know before switching
What is a cloud RADIUS server?
A cloud RADIUS server provides network authentication as a managed service. Instead of running FreeRADIUS, NPS, or Cisco ISE on your own hardware, IronWiFi operates the RADIUS infrastructure for you - with 99.9% uptime, automatic failover, and zero maintenance on your end.
How is cloud RADIUS different from running FreeRADIUS or NPS?
With FreeRADIUS or NPS, you maintain the server OS, apply security patches, manage certificates, configure failover, and handle scaling. With IronWiFi, all of that is handled for you. You configure authentication policies through a dashboard and we run the infrastructure across 6 global regions.
Will my existing access points work?
Yes. Any access point or network switch that supports standard RADIUS (which is virtually all of them) works with IronWiFi. We support 45+ brands including Ubiquiti, Meraki, Aruba, Ruckus, Fortinet, MikroTik, TP-Link, and Cambium. Check our full compatibility list.
How do I connect my identity provider?
IronWiFi integrates natively with Azure AD (Entra ID), Google Workspace, Okta, OneLogin, JumpCloud, and any LDAP or Active Directory. Setup takes minutes - your users authenticate with their existing work credentials.
What happens if IronWiFi has an outage?
We run RADIUS servers across 6 global regions with automatic failover. If one region goes down, your traffic routes to the nearest healthy region automatically. We maintain 99.9% uptime backed by an enterprise SLA, and most access points cache authenticated sessions locally as a safety net.
Is cloud RADIUS secure enough for regulated industries?
Absolutely. IronWiFi is SOC 2 Type II certified and GDPR compliant. We support WPA3-Enterprise with 192-bit security, EAP-TLS certificate authentication, and provide complete audit trails. Financial services, healthcare, and government organizations use our platform.
Ready to Move Your RADIUS to the Cloud?
Stop maintaining servers. Stop worrying about uptime. Stop wasting your team's time on infrastructure that should just work. Set up IronWiFi's cloud RADIUS in under 5 minutes and get back to work that matters.
