Wi-Fi Security Focus Shifts Beyond Encryption

Wi-Fi security solutions have evolved significantly since last year, and now protect wireless networks through encryption (WPA3), authentication (802.1X or pre-shared keys), wireless intrusion prevention to detect rogue and spoofed access points, and access policy that determines what each connected device may reach.

The baseline for Wi-Fi security has shifted from WPA2 to WPA3, which is now the standard requirement for Wi-Fi 6E and Wi-Fi 7 certification. Any new deployment should use WPA3 with transition mode used only where legacy devices force it and a date set to remove it.

The key decision in wireless security has moved beyond encryption to what a device can reach after connecting. This is especially important for IoT devices, which cannot run 802.1X supplicants or hold certificates. The way a platform handles these devices, such as dynamic pre-shared keys or MAC authentication with profiling, is often the deciding factor.

Cisco Meraki's cloud dashboard and Air Marshal detection are ideal for multi-site management, while HPE Aruba offers the deepest wireless security feature set, including dynamic segmentation tying identity to network policy. Fortinet provides the best value for existing firewall estates, with its FortiAP access points managed directly from FortiGate.
