CrowdStrike’s Host Management service runs an automatic-purge routine. When a sensor has not checked in to the Falcon Cloud for 90 consecutive days, its host record is deleted from the Host Management view and simultaneously removed from the Trash container; after that point no console record remains. This 90-day interval is hard-coded unless the customer has requested a different retention policy from Support.

A. 45 Days – host is only hidden (or moved to Trash, depending on tenant setting); it is not yet purged from both views.
B. 60 Days – no purge action is triggered at this point by default.
C. 75 Days – lies between the “hidden” threshold and the definitive 90-day purge; nothing is removed from both pages yet.
