Traditional IoT Auth vs IronWiFi
Eliminate security gaps and manual configuration with enterprise-grade IoT authentication
Traditional IoT Authentication
- Shared PSK passwords across all devices
- No individual device identity or tracking
- Manual VLAN configuration per device
- Cannot revoke single device access
- Captive portals don't work for headless devices
- No audit trail of device connections
- Flat network with no segmentation
IronWiFi IoT Authentication
- Per-device certificate or MAC identity
- Complete audit trail of every connection
- Automatic VLAN via RADIUS attributes
- Instant revocation of any device
- Works with any headless device
- Real-time visibility into device activity
- Dynamic segmentation by device type
No credit card required - 14-day free trial - Works with any access point vendor
Enterprise IoT Authentication Features
Everything you need to secure and segment your IoT infrastructure
Certificate-Based Authentication
EAP-TLS authentication for high-security IoT deployments. Each device gets a unique certificate for mutual authentication without passwords. Learn about WPA-Enterprise →
MAC Authentication Bypass
Authenticate devices without 802.1X support using their MAC address. Perfect for legacy equipment, printers, and simple sensors.
Dynamic VLAN Assignment
Automatically segment devices into the correct VLAN based on device type, MAC address, certificate attributes, or custom policies.
Zero-Touch Provisioning
Deploy certificates to smart devices via SCEP/EST. Integrate with MDM platforms for fully automated device enrollment.
Device Lifecycle Management
Track, audit, and revoke devices from a central console. See connection history, last seen timestamps, and authentication events.
Multi-Vendor Support
Works with Cisco, Aruba, Ruckus, Meraki, Ubiquiti, Fortinet, and any 802.1X-capable network infrastructure.
How IoT Authentication Works
From device registration to automatic network segmentation in four steps
Register Device
Add device MAC address or provision a certificate. Import devices in bulk via CSV or API integration with your asset management system.
Configure Policy
Set VLAN assignment rules, authentication method (802.1X or MAB), access schedules, and any custom RADIUS attributes.
Device Connects
Device authenticates via 802.1X (EAP-TLS/PEAP) or MAC Authentication Bypass. IronWiFi validates and returns access decision.
Automatic Segmentation
RADIUS returns VLAN attributes to your access point. Device is placed in the correct network segment automatically.

Frequently Asked Questions
Common questions about IoT device authentication
How do I authenticate devices without 802.1X support?
Use MAC Authentication Bypass (MAB). IronWiFi authenticates devices by their MAC address and can apply device-specific policies including VLAN assignment. Combine with device profiling for enhanced security.
Can I use certificates for IoT devices?
Yes. For IoT devices that support 802.1X, you can use EAP-TLS with device certificates. IronWiFi's SCEP server can provision certificates to smart devices via MDM or zero-touch enrollment.
How does automatic VLAN assignment work?
When a device authenticates, IronWiFi RADIUS returns VLAN attributes to your access point. The AP places the device in the assigned VLAN automatically. You can assign VLANs based on device type, MAC address, certificate, or custom policies.
What happens when a device is compromised?
Revoke the device instantly from the IronWiFi console. The device loses network access immediately. For MAC auth, remove the MAC from your whitelist. For certificates, revoke the certificate and the CRL is updated in real-time.
Can I integrate with my device inventory system?
Yes. IronWiFi provides REST APIs for device management. Sync your CMDB, asset management, or IoT platform with IronWiFi to automatically provision and deprovision devices.
What about devices that change MAC addresses?
For devices with randomized MACs (like some consumer IoT), use certificate-based authentication or configure the device to use a static MAC. IronWiFi also supports MAC patterns for device groups.
