The Coverage Explorer (full page at /tag-coverage-explorer) shows how your tags overlap across the device estate. It’s the safety net for tag design — every time you change a Logic Engine rule, the Coverage Explorer tells you whether the result is what you expected. Reach it from the Coverage Explorer link in the top-right of Settings → Tags.

What it shows

The page header shows the total count (e.g. 1,229 devices) and the ”% of these devices have one or more tags” coverage metric. A side configuration panel lets you toggle Show only active devices and Show only name based dynamic tags.

How to access it

1

Open Settings → Tags

Settings → Tags from the Settings left rail.
2

Click Coverage Explorer

Top-right of the Tags page. This opens the full Coverage Explorer page at /tag-coverage-explorer.
3

Click View Devices on any segment

Drills through to the Devices grid filtered by the implied tag query — useful for sanity-checking individual devices.

Why it matters

Tags drive Vitals scope (which controls a device is expected to have), Action targeting (which devices automations apply to), and data-filter access (who can see what). A misconfigured tag has cascading effects. The Coverage Explorer surfaces three classes of problem before they cause noise:
  1. Devices in zero tags — they sit outside Vitals scope entirely, so gaps don’t show up as findings. Often the most consequential miss.
  2. Devices in conflicting tags — e.g. a device tagged both End-User and Server may have contradictory Vitals requirements.
  3. Empty tags — a Logic Engine rule that matches nothing usually means the query is wrong, not that the population is genuinely zero.

When to use it

Best practices

Untagged devices are operationally invisible to Vitals and Actions. Either they need a tag (the rule was wrong) or they need an exclusion tag like Stock to mean “intentionally out of scope right now”. See Tags & Logic Engine → Best practices.
Coverage Explorer is the only fast way to see the impact of a rule change without scrolling Devices. Save the click trip.
Freshly-discovered devices that haven’t been baselined yet should sit in a Stock tag where security controls aren’t required. Coverage Explorer makes the move-out cadence visible.
