Get Your IoT Devices Online Without the Headaches
Connecting thousands of IoT devices shouldn't be complicated. We'll handle the certificates and MAC authentication while your devices automatically land in the right network segment. No user interaction needed.
From $3/device/mo (billed annually) with IoT Devices plan · SOC 2 Compliant
IoT WiFi authentication secures headless devices like sensors, cameras, and smart displays by using certificate-based or MAC authentication instead of user credentials. IronWiFi automates IoT device onboarding with automatic VLAN segmentation, certificate provisioning, and network micro-segmentation — connecting thousands of devices without manual configuration.

What Is Wrong With Traditional IoT Authentication?
Say goodbye to security gaps and tedious manual setup
The Old Way (Painful)
- One password for everything - not great for security
- Can't tell devices apart or track them
- Setting up VLANs manually for each device
- Can't kick off just one device when there's a problem
- Login pages don't work for devices without screens
- No way to know what connected and when
- Everything on one flat network - risky
With IronWiFi (Easy)
- Each device gets its own identity - certificate or MAC
- See exactly what's connecting and when
- VLANs are assigned automatically - no manual work
- Revoke any device instantly with one click
- Works perfectly with screenless devices
- Watch device activity in real-time
- Devices are automatically separated by type
No credit card needed. 14 days free. Works with whatever access points you've got.
What Features Does IronWiFi Offer for IoT Security?
We've built all the tools so you can focus on what matters
Certificates for Each Device
Your high-security devices get their own unique certificate - no shared passwords needed. It's the gold standard for IoT authentication per NIST guidelines, and we make it simple. Learn about WPA-Enterprise →
MAC-Based Auth for Simple Devices
Got devices that don't support fancy authentication? No problem. We'll identify them by their MAC address - perfect for printers, sensors, and older equipment.
Automatic Network Segmentation
Devices land in the right VLAN automatically based on what they are. No manual config needed - just set your rules once and forget about it.
Set It Up Once, Then Relax
Deploy certificates automatically through SCEP/EST. Hook it up to your MDM and new devices configure themselves. That's it.
Keep Track of Every Device
See what's connected, when it last checked in, and its entire connection history. Need to revoke access? One click and it's done.
Works With Your Existing Gear
Cisco, Aruba, Ruckus, Meraki, Ubiquiti, Fortinet - we play nice with all of them. If it supports 802.1X, we've got you covered.
How Does IoT Authentication Work?
Four simple steps from adding a device to it landing in the right network
Add Your Device
Pop in the MAC address or set up a certificate. Need to add a bunch at once? Upload a CSV or connect to your asset management system.
Set Your Rules
Tell us which VLAN each device type should use, how to authenticate, when they can connect, and any other settings you need.
Device Shows Up
When a device tries to connect, our RADIUS server checks its credentials - whether that's a certificate, password, or just its MAC address. Quick and automatic.
It Goes to the Right Place
We tell your access point exactly which VLAN to put the device in. It happens automatically - no manual switching needed.
Which Authentication Method Is Right for Each Device?
Different devices need different approaches - here's what we support
| Method | Security Level | Best For | IronWiFi Support |
|---|---|---|---|
| EAP-TLS | Highest | Smart devices, medical gear, building automation systems | ✓ Full Support |
| PEAP-MSCHAPv2 | High | Payment terminals, kiosks, company-managed devices | ✓ Full Support |
| MAC Authentication | Medium | Printers, sensors, older equipment that can't do 802.1X | ✓ Full Support |
| MAC + Profiling | High | When you want extra security on top of MAC auth | ✓ Full Support |
Where Is IoT Authentication Used Across Industries?
IoT is everywhere - here's how different industries put it to work
Smart Buildings
HVAC, lighting, door access, elevators - all those building systems that need to talk to your network.
Healthcare
Patient monitors, IV pumps, imaging equipment, and all those connected devices that can't go offline.
Manufacturing
Sensors, PLCs, robots, quality monitors - everything on the factory floor that needs network access.
Retail
Payment terminals, digital signs, inventory scanners, RFID readers - the tech that keeps stores running.
Education
Projectors, smart boards, lab gear, 3D printers - all the classroom tech students and teachers rely on.
Hospitality
Room TVs, thermostats, door locks, minibars, service tablets - giving guests a connected experience.
Which Network Equipment Is Compatible With IronWiFi?
We integrate with all the major network equipment vendors
Got Questions? We've Got Answers
Here's what people usually ask about IoT authentication
What if my devices don't support 802.1X?
No worries - that's what MAC Authentication Bypass is for. We'll identify devices by their MAC address and still apply all your policies, including VLAN assignment. Add device profiling if you want extra security.
Can I use certificates for IoT devices?
Absolutely! If your devices support 802.1X, you can use EAP-TLS with device certificates. Our SCEP server can push certificates to smart devices through your MDM automatically.
How does automatic VLAN assignment work?
When a device connects, we tell your access point which VLAN to put it in. You set the rules once (by device type, MAC, certificate, whatever you want) and it just works from there.
What if a device gets compromised?
Hit the revoke button and it's off your network instantly. For MAC auth, just remove it from your list. For certificates, revoke it and we update the revocation list right away.
Can I connect this to my existing systems?
Yep! We've got REST APIs for device management. Connect your CMDB, asset management system, or IoT platform and devices will be added and removed automatically.
What about devices that randomize their MAC?
Some devices do that for privacy. You can either use certificate-based auth instead, or set the device to use a static MAC. We also support MAC patterns if you want to group similar devices together.
