According to theCrowdStrike Falcon Data Replicator (FDR) Add-on for Splunk Guide, quarantined files are never deleted from the host unless you manually delete them or release them from quarantine2.When you release a file from quarantine, you are restoring it to its original location and allowing it to execute on any host in your organization2.This action also removes the file from the quarantine list and deletes it from the CrowdStrike Cloud2.
