An exclusion is an entity that you specify as an exception to remediation actions. The excluded entity might still get detected, but no remediation actions are taken on that entity. That is, the detected file or process wont be stopped, sent to quarantine, removed, or otherwise changed by Microsoft Defender for Endpoint.
To define exclusions across Microsoft Defender for Endpoint, perform the following tasks:
- Define exclusions for Microsoft Defender Antivirus
- Create “allow” indicators for Microsoft Defender for Endpoint
- [Define exclusions for Microsoft Defender Antivirus](#exclusions-for-microsoft-defender-antivirus)
- [Create “allow” indicators for Microsoft Defender for Endpoint](#indicators-for-microsoft-defender-for-endpoint)
Microsoft Defender Antivirus exclusions don't apply to other Microsoft Defender for Endpoint capabilities, including [endpoint detection and response](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/overview-endpoint-detection-response), [attack surface reduction rules](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/attack-surface-reduction), and [controlled folder access](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/controlled-folders). Files that you exclude using the methods described in this article can still trigger alerts and other detections. To exclude files broadly, use [custom indicators](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/manage-indicators), such as "allow" indicators for Microsoft Defender for Endpoint.
