Trio now supports Device Single Sign-On (SSO) within its Zero Trust framework, enabling users to authenticate seamlessly while ensuring access is strictly bound to trusted, compliant devices.

This update removes repetitive login friction without weakening security controls, aligning user experience with Zero Trust principles.

What’s New

Device SSO allows users to authenticate once per trusted device, eliminating repeated credential prompts while maintaining continuous device validation. Authentication is no longer session-based alone—it is device-aware and policy-enforced.

Access is granted only when:

• The user identity is verified

• The device is enrolled and trusted

• Zero Trust policies are satisfied in real time

How It Works (Technical Overview)

• During initial authentication, Trio binds the user session to a specific managed device

• The device is continuously evaluated for:

  • Enrollment status

  • Platform trust

  • Compliance with assigned policies

• As long as the device remains trusted, users are automatically authenticated without re-entering credentials

If the device state changes (e.g., policy violation, device removal, trust revocation), SSO access is immediately invalidated.

This ensures authentication is dynamic, not static.

Why It Matters

Traditional SSO improves usability but often assumes device trust implicitly. Device SSO in Trio removes that assumption by enforcing continuous trust verification.

Key advantages:

• Reduced credential fatigue for end users

• Stronger protection against credential theft and session hijacking

• Immediate access revocation when device trust changes

• Better alignment with Zero Trust and least-privilege models

Platform Impact

• Builds directly on Trio’s IdP integration

• Enhances Conditional Access and Device Login workflows

• Improves authentication consistency across managed environments

• Reduces authentication-related support overhead

Who Should Use This

• Organizations enforcing Zero Trust access policies

• Teams managing remote or hybrid workforces

• Environments where usability and security must coexist

• IT teams seeking to reduce login friction without sacrificing control
