### Classify an alert
Alerts can be classified as false positives or true positives in the Microsoft Defender Security Center. Classifying alerts helps train Microsoft Defender for Endpoint so that, over time, you'll see more true alerts and fewer false alerts.
1. Go to the Microsoft Defender Security Center ([https://securitycenter.windows.com](https://securitycenter.windows.com)) and sign in.
2. Select **Alerts queue**, and then select an alert that is a false positive.
3. For the selected alert, select **Actions** > **Manage alert**. A flyout pane opens.
4. In the **Manage alert** section, select either **True alert** or **False alert**. (Use **False alert** to classify a false positive.)
1. Go to the Microsoft Defender Security Center ([https://securitycenter.windows.com](https://securitycenter.windows.com)) and sign in.
2. Select **Alerts queue**, and then select an alert.
3. For the selected alert, select **Actions** > **Manage alert**. A flyout pane opens.
4. In the **Manage alert** section, select either **True alert** or **False alert**. (Use **False alert** to classify a false positive.)
> [!TIP]
> For more information about suppressing alerts, see [Manage Microsoft Defender for Endpoint alerts](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/manage-alerts). And, if your organization is using a security information and event management (SIEM) server, make sure to define a suppression rule there, too.
