IronWiFi vs FortiAuthenticator
FortiAuthenticator is a capable authentication server — inside the Fortinet ecosystem. If you want WiFi authentication that works with any vendor, IronWiFi gets you there without the hardware.
IronWiFi is a cloud-native WiFi authentication platform, while FortiAuthenticator is Fortinet's appliance-based authentication server designed for the Fortinet ecosystem. FortiAuthenticator requires hardware or VM licensing plus per-user upgrades and annual FortiCare contracts, with full value tied to FortiGate firewalls and FortiAP access points. IronWiFi delivers RADIUS, Cloud PKI, and captive portal Contact us for custom pricing.
Appliance-Based vs Cloud-Native
FortiAuthenticator is Fortinet's dedicated authentication server, supporting RADIUS, LDAP, SAML, and Fortinet's own Single Sign-On (FSSO). It's deployed as a hardware appliance or VM, and it works best when paired with FortiGate firewalls and FortiAP access points. Outside the Fortinet ecosystem, you lose a significant chunk of its value. IronWiFi is cloud-native and works with 45+ access point vendors from day one — no appliances, no ecosystem requirements. And with step-by-step setup guides for every supported vendor, you're not trading Fortinet's documentation for guesswork.
The Hidden Cost of Hardware Lock-In
FortiAuthenticator requires purchasing a hardware appliance or VM license, plus per-user upgrade licenses and annual FortiCare support contracts. Add in the FortiGate firewalls and FortiAP access points you'll need to get full value, and costs add up fast. IronWiFi pricing is custom — contact sales with everything included — no hardware, no upfront costs, no ecosystem tax.

When Does FortiAuthenticator Make Sense?
- You're already invested in the Fortinet ecosystem (FortiGate, FortiAP, FortiSwitch)
- You need Fortinet Single Sign-On (FSSO) across FortiGate policies
- FortiToken MFA is a requirement for VPN or admin access
- Your organization mandates on-premises authentication servers
- You need LDAP proxy or Active Directory integration specific to Fortinet workflows
When Is IronWiFi the Better Fit?
- You use access points from multiple vendors (or not Fortinet)
- You want cloud-native RADIUS without managing appliances or VMs
- Transparent, published pricing matters to you
- You need captive portals, guest WiFi, or OpenRoaming
- Cloud PKI and certificate management should be included, not bolted on
- You want to be live in 30 minutes with step-by-step guides for 45+ hardware vendors
- Month-to-month billing flexibility is important (no upfront hardware costs)
So, What's the Bottom Line?
If your network runs on Fortinet end-to-end and you need FSSO, FortiToken, and deep FortiGate integration, FortiAuthenticator fits naturally into that stack. But if WiFi authentication is what you actually need — and you don't want to be locked into one vendor's hardware ecosystem — IronWiFi delivers cloud RADIUS that works with any AP, at transparent pricing, with zero appliances to manage.
