AuthenTrend Zero Trust Identity Authentication System is built on the principle of ‘Never Trust, Always Verify,’ providing a secure network access solution. It integrates the ZTA framework with ATKey, a FIDO2 hardware security key, while adopting an open architecture that balances scalability and enterprise autonomy, enabling flexible deployment and fostering business partner collaboration. The system is designed in accordance with the National Institute for Cyber Security’s (NICS) 'Government Zero Trust Network Identity Authentication Compliance Verification' standards and meets the U.S. NIST deployment standards (800-63-3) at IAL3/AAL3/FAL2 levels, delivering a high-security identity authentication mechanism.
