Cisco EAP-FAST Module

Cisco EAP-FAST Module by Cisco Systems, Inc. is a network authentication component that implements EAP-FAST (Extensible Authentication Protocol – Flexible Authentication via Secure Tunneling). It is used primarily in enterprise Wi‑Fi and wired 802.1X environments to securely authenticate users and devices.

The module establishes an encrypted TLS tunnel—typically using a Protected Access Credential (PAC)—to protect usernames, passwords, and other credentials during authentication. It supports mutual authentication, secure key exchange, and fast reauthentication to improve roaming performance. EAP-FAST helps organizations avoid deploying client certificates while still maintaining strong security.

You’ll commonly see this module installed alongside Cisco Secure Client/AnyConnect or as part of an enterprise network setup, where it is invoked by the Windows native supplicant or a Cisco network manager. It has no standalone user interface and runs in the background. If your organization uses EAP-FAST, this component is required for network access; if not, it generally remains inactive without affecting normal operation.

Cisco EAP-FAST Module is developed by Cisco Systems, Inc. and is used by 21,169 users of Software Informer. This particular product is not fit to be reviewed by our informers.
