The first test is a blocked sign-in
When a PAW rollout is marked complete, I ask to see two sign-ins for the same protected task. One comes from the approved workstation and succeeds. The other comes from a normal laptop and is blocked by the intended policy. A screenshot of a compliant device proves less than this pair of tests: the pair shows that the access path is actually enforced.
I would run the test for the browser portal and for every command-line, API, remote desktop, or jump-host route the team uses. A browser rule does not automatically protect a different interface. I record the account, device, application, policy result, and timestamp so the result can be checked in sign-in logs.
Write a runbook before the first failure
A secure design that blocks a legitimate administrator without a recovery path will be bypassed. My runbook would explain how a PAW is enrolled, replaced, patched, and retired; who handles a lost device; and how a user reports a blocked task. It would also say how to restore access without turning off the protection for everyone.
Emergency accounts are a separate runbook. Microsoft recommends at least two cloud-only emergency access accounts with permanent active Global Administrator assignments and regular testing. Their sign-ins should generate high-priority alerts. I would test the full recovery sequence, including access to a designated secure workstation and credentials, then record the test result and owner.
Watch the signals that reveal drift
The useful dashboard is small. I would track protected roles without a mapped PAW path, privileged sign-ins from unapproved devices, standing high-impact role assignments, unhealthy PAWs, and exceptions past review date. A trend matters more than a decorative compliance percentage: a new unprotected admin interface can make last month’s good score misleading.
Sign-in logs and Conditional Access reporting show which policy evaluated a session and why it allowed or blocked it. PIM logs explain activation; endpoint telemetry explains device health. Review these together when an administrator says a workflow has stopped working. A policy result alone rarely tells the whole story.
Treat exceptions as engineering work
An exception should name the task, owner, compensating control, expiry date, and a plan to remove the gap. If a legacy console cannot check device compliance, I would consider a controlled intermediary and test that it cannot be reached from a normal laptop. If a vendor needs temporary access, I would scope the role and duration before adding a broad bypass.
Finally, I would repeat the allowed and denied tests after major policy changes, device image updates, new admin tools, and role redesigns. A PAW is a working access path, not a device purchase. The operational loop is what keeps the original trust boundary real.
