Posture tokens are temporary and have a configurable expiry timer (often defaulted to 5 minutes). If a device disconnects and remains inactive for longer than this threshold, ClearPass clears the token to ensure it doesn't grant access based on potentially stale health data. When the device returns after 10 minutes, it must perform a new health check to regain its "Healthy" status.

In a cloud-first environment, the "perimeter" has effectively disappeared. A Zero Trust model is the only effective defense because it assumes the network is already compromised. ClearPass enables this through continuous monitoring ; if a device's status changes (e.g., an OnGuard health check fails or an EMM marks it as "non-compliant"), ClearPass uses "closed-loop" logic to immediately update the network's enforcement via RADIUS CoA, ensuring the threat is contained in real-time.

When a guest is redirected to the captive portal, their browser sends an HTTP Get request. Included in the headers of this request is the User-Agent string (e.g., Mozilla/5.0 (iPhone; CPU iPhone OS 17_0...)). ClearPass Guest parses this string to identify the specific OS and browser version. This information is then shared with the Policy Manager to update the endpoint database, providing immediate profiling context even before the user logs in.

In ClearPass service configuration, the Posture tab is not visible by default. To enable health check logic, the administrator must check the "Posture Compliance" box in the Service tab. This adds the Posture configuration screen where the administrator can select the specific Posture Policy that will evaluate the reports sent by the OnGuard agents.
