Trio’s Conditional Access module introduces policy-driven, context-aware access control that evaluates both device posture and real-time location trust before allowing authentication or session continuation. This enables Zero Trust decisions that are not static or identity-only, but continuously validated against device and environmental context.

What’s New

Conditional Access in Trio adds a dedicated enforcement layer where access is granted only when a request satisfies multiple signals, including:

• Device-based access: whether the requesting endpoint is enrolled, trusted, and compliant

• Geolocation trust: whether the request originates from an approved geographic context, as defined by policy

This module enables “allow/deny/step-up” behavior at the moment of access—based on the device’s current state and the user’s location context.

How It Works (Technical Overview)

When a user or device attempts to access a protected resource, Trio evaluates an access policy using a set of conditional inputs:

1) Device posture evaluation

• Enrollment status (managed vs unmanaged)

• Compliance state against assigned policies (e.g., encryption enabled, screen lock, OS requirements)

• Device trust state (e.g., approved device identity, risk posture derived from agent telemetry where applicable)

2) Real-time location evaluation

• Location is assessed against policy-defined trust criteria (e.g., permitted regions, office locations, or geofenced zones)

• If location trust is required, access is allowed only if the device location matches the expected context at request time

3) Decision and enforcement

• Trio returns an access decision:

  • Allow if all conditions pass

  • Deny if any mandatory condition fails

  • Conditional/step-up (where supported) if policy requires additional verification when risk is elevated (e.g., location mismatch or partial compliance)

Critically, this model supports dynamic enforcement: if device compliance changes or location context shifts, access can be re-evaluated based on policy.

Why It Matters

Identity-based access alone cannot prevent access from:

• A valid user signing in from an unmanaged device

• A trusted device operating outside approved geographic context

• A device that was compliant yesterday but is non-compliant now

Conditional Access addresses these gaps by enforcing contextual authorization at runtime. The result is stronger resistance to credential theft, unauthorized access, and policy drift.

Platform Impact

• Acts as a primary enforcement layer for Zero Trust access decisions

• Integrates with IdP, Device SSO, and Device Login by adding context-based gating

• Improves auditability by linking access outcomes to:

  • device identity

  • device compliance state

  • location context at time of request

• Reduces manual incident response by preventing risky access paths by default

Who Should Use This

• Organizations implementing Zero Trust across distributed teams

• IT/security teams that need to restrict access by trusted device + trusted location

• Environments with sensitive data requiring deterministic access controls and audit trails

• Teams that need policy-driven enforcement rather than manual approvals
