What is clean room ransomware recovery?

Clean room ransomware recovery restores systems or data into an isolated environment before returning them to production. The clean room gives responders a controlled place to inspect recovery data, validate application behavior, check for malware or persistence, and confirm that the restored state will not reintroduce the incident.

A clean room is most effective when the recovery point has already been validated. Otherwise, the isolated environment becomes the place where teams discover, under pressure, that the selected backup was not clean.
