RADIUS remains a practical choice for Cisco AnyConnect MFA because it allows organizations to add stronger authentication without replacing their existing VPN setup. When adding MFA to Cisco AnyConnect, the ASA or Firepower device can forward login requests to a RADIUS server, where the user’s password is checked first and an OTP is then required before access is approved. Protectimus uses this RADIUS-based approach to support authentication methods such as TOTP apps and hardware tokens while keeping the existing AnyConnect client and VPN architecture in place. This makes RADIUS a flexible option for businesses that want stronger remote access security with minimal infrastructure changes.
