FreeRADIUS is Great. Until It Isn't.
We're big fans of open source. But"free" has some expensive fine print. Let's break down what FreeRADIUS actually costs - and when it makes sense to go a different route.
IronWiFi is a cloud-managed RADIUS platform that replaces self-hosted FreeRADIUS servers with a fully managed service. FreeRADIUS is free to download but carries significant hidden costs in servers, sysadmin labor, and ongoing maintenance. IronWiFi requires zero infrastructure, deploys in 30 minutes, and includes captive portals, OpenRoaming, and native identity provider integrations that FreeRADIUS lacks. Contact sales for pricing.
What Does FreeRADIUS Actually Cost?
Look, FreeRADIUS is genuinely excellent software - there's a reason millions of people use it. But here's the thing:"free" doesn't mean"costs nothing." As of 2026, when you add up the servers, the expertise, and all those hours keeping it running, the hidden costs are significant. That's a lot of expense hiding behind a zero-dollar download.
With IronWiFi, you get the same RADIUS power pricing customized to your setup. No servers to babysit, no Linux wizardry required, and we provide multi-region redundancy with automatic failover. Pretty straightforward, right?
Here's How They Stack Up
| Factor | IronWiFi | FreeRADIUS |
|---|---|---|
| Software Cost | Contact Sales | Free (open source) |
| Infrastructure Cost | None (cloud) | Servers required (your cost) |
| Setup Time | 30 minutes | 2-6 weeks |
| Linux Expertise Required | No | Yes (advanced) |
| Maintenance Hours/Month | 0 hours | 10-20 hours |
| High Availability | Built-in (6 regions) | Manual configuration |
| Security Patches | Automatic | Manual |
| Uptime SLA | Multi-region failover | None |
| Support | 24/7 included | Community forums |
| 3-Year TCO (500 users) | Contact sales | Significant (servers + staff time) |
So What Does"Free" Really Cost?
Consider a typical 500-user setup over 3 years. The gap between"free software" and"free to run" is significant.

When Does FreeRADIUS Actually Make Sense?
We're not going to pretend IronWiFi is right for everyone. FreeRADIUS might be your best bet if:
- You've got Linux admins who eat RADIUS configs for breakfast
- You need to customize things way beyond what standard RADIUS offers
- Regulations say everything has to stay on-premise (no exceptions)
- You're at a university or research lab with infrastructure already in place
- You want to really understand how RADIUS works under the hood
When Is IronWiFi the Smarter Move?
On the other hand, you'll probably be happier with IronWiFi if:
- You'd rather be done in hours than spend weeks on setup
- Your team doesn't have a Linux/RADIUS expert (and doesn't want to become one)
- You need Microsoft Entra ID, Okta, or Google integration without the headaches
- You want a nice captive portal for guest WiFi
- OpenRoaming or Passpoint is on your roadmap
- You like knowing exactly what you'll pay each month (no surprise maintenance bills)
- You need multi-region redundancy with automatic failover
The Bottom Line
FreeRADIUS is fantastic software - seriously. But"free" and"costs nothing" are two very different things. For most teams, IronWiFi saves significantly over three years once you count all the hidden costs of self-hosting. Plus you get captive portals, modern identity provider support, OpenRoaming, and an actual dashboard - stuff that would take months to build on FreeRADIUS.
Ready to switch? It takes about 30 minutes. Your authentication methods stay the same. Your maintenance headaches disappear.
