SecOps Signal does not execute queries against private telemetry. Paste the query into Microsoft Sentinel Log Analytics or Defender advanced hunting and review it first. Passed structure and schema checks; tenant execution is not verified.

Query anatomy

Static check against a reviewed column list

— This query has no final project stage to list.

“Listed” only means the column name appears in the reviewed list for that table. It does not confirm the column exists in your tenant's current schema, and per-column purposes are not recorded.
