Phishing-Resistant VPN Access with ATKey.Pro
Secure enterprise VPN access with phishing-resistant, fingerprint-based authentication.
By integrating ATKey.Pro to a central Identity Provider, organizations can replace vulnerable OTPs and push notifications with FIDO2 hardware security keys, delivering stronger security and a seamless VPN login experience.
The Challenge
Remote access is one of the most common entry points for attackers.
Organizations relying on passwords, OTPs, or push-based MFA for VPN access remain exposed to:
Phishing attacks and credential theft
MFA fatigue and push-approval abuse
To strengthen the security, it is necessary to implement authentication procedures that are not easily side-supported or abused and do not add unnecessary friction to the users.
The Solution
Use SAML compatible VPN and IdP to enforce FIDO2 passwordless authentication and fingerprint user verification via ATKey.Pro for access to the corporate network.
This setup introduces passkey authentication and replaces vulnerable second factors with biometric verification, while simplifying the login experience.
How It Works
The user starts a VPN connection from the VPN client
The VPN server redirects verification to a central Identity Provider
The user inputs the login credentials and verifies its identity tapping on their ATKey.Pro for MFA.
Upon successful authentication, secure VPN access is granted
Why ATKey.Pro
ATKey.Pro combines something you have (a hardware security key) with something you are (your fingerprint):
FIDO2-certified, phishing-resistant authentication
Fingerprint verification in under one second
Credentials stored securely on the device
No reusable passwords or codes
This ensures VPN access is bound to the user and the device, not a password.
