Secure AI Workspaces for Unmanaged Devices and External Users

BlueBear governance evidence ladder connecting identity policy execution and outcome records
Production agents need a control decision and an evidence record for every consequential action.

Unmanaged devices do not need an all-or-nothing policy. A secure enterprise workspace can grant a reduced capability set based on identity assurance, device posture, data class, action risk, location, and session state.

Risk-tiered access

TierExample accessControls
ViewLow-sensitivity dashboards and approved outputs.Phishing-resistant sign-in where required, short session, watermark, no secret display.
InteractRun bounded agents using assigned read-only tools.Step-up authentication, tenant checks, content policy, rate and budget limits.
ChangeExecute external writes or approve high-impact actions.Managed device or approved virtual workspace, bound approval, fresh authentication.
AdministerChange roles, integrations, policies, or retention.Managed privileged workstation, separate admin identity, enhanced monitoring.

Browser and session controls

Use secure, HTTP-only cookies; prevent tokens in local storage where possible; bind sessions to risk signals; rotate on privilege change; expire idle and absolute lifetimes; and revoke centrally. Do not treat user-agent strings as trustworthy device posture.

Data movement

Control downloads, print, clipboard, copy/paste, uploads, browser extensions, webhooks, email, and connector exports according to data class. When controls cannot prevent capture, reduce exposed data, watermark it, and record access for investigation.

External users

Use a sponsor, explicit workspace membership, expiry, restricted role, allowed domains, and periodic recertification. Remove access when the engagement ends and preserve the membership and export history required by policy.

Map an external-collaboration workspace to BlueBear roles and action policies.
