Where can you find a list of hosts that have not communicated with the CrowdStrike...

A list of hosts that have not communicated with the CrowdStrike cloud is found in Inactive Sensors . The Inactive Sensors report identifies sensors that have not reported within a given timeframe and is intended for deployment coverage and operational health review. Host Groups organize systems for policy assignment but are not the report for cloud communication gaps. The Activity Dashboard focuses on detections, incidents, and security activity rather than sensor check-in status. Sensor Report provides an overview of active sensors, while Inactive Sensors specifically addresses hosts that have stopped reporting. CCFA dashboard and report guidance identifies Inactive Sensors as the report administrators use to locate endpoints that may be powered off, decommissioned, disconnected, or experiencing communication problems.
