View and manage actions in the Action center

Applies to:

• Microsoft Defender XDR

Threat protection features in Microsoft Defender XDR can result in certain remediation actions. Here are some examples:

• Automated investigations can result in remediation actions that are taken automatically or await your approval.
• Antivirus, antimalware, and other threat protection features can result in remediation actions, such as blocking a file, URL, or process, or sending an artifact to quarantine.
• Your security operations team can take remediation actions manually, such as during advanced hunting or while investigating alerts or incidents.

Note

You must have appropriate permissions to approve or reject remediation actions. For more information, see the prerequisites.

To navigate to the Action center, take one of the following steps:

• Go to https://security.microsoft.com/action-center; or
• In the Microsoft Defender portal (https://security.microsoft.com), in the Automated investigation & response card, select Approve in Action Center.
