| EDR Product | Unload Command | Difficulty | | :--- | :--- | :--- | | SentinelOne | sentinelctl.exe unload --token X | High (requires token) | | CrowdStrike | CSFalconctl -u -t X | High (requires token) | | Microsoft Defender | MpCmdRun.exe -RemoveDefinitions | Low (but reloads quickly) | | Carbon Black | CbDefense.exe --unload --password X | Medium | | Traditional AV | net stop <service> | Very Low | Sentinelctl.exe Unload
