Configure email notifications for security alerts


Azure Security Center and Azure Defender are now called Microsoft Defender for Cloud. We've also renamed Azure Defender plans to Microsoft Defender plans. For example, Azure Defender for Storage is now Microsoft Defender for Storage. Learn more about the recent renaming of Microsoft security services.

Security alerts need to reach the right people in your organization. By default, Microsoft Defender for Cloud emails subscription owners whenever a high-severity alert is triggered for their subscription. This page explains how to customize these notifications.

Use Defender for Cloud's Email notifications settings page to define preferences for notification emails including:

  • who should be notified - Emails can be sent to select individuals or to anyone with a specified Azure role for a subscription.
  • what they should be notified about - Modify the severity levels for which Defender for Cloud should send out notifications.

To avoid alert fatigue, Defender for Cloud limits the volume of outgoing mails. For each subscription, Defender for Cloud sends:

  • a maximum of one email per 6 hours (4 emails per day) for high-severity alerts
  • a maximum of one email per 12 hours (2 emails per day) for medium-severity alerts
  • a maximum of one email per 24 hours for low-severity alerts

You can send email notifications to individuals or to all users with specific Azure roles.

  1. From Defender for Cloud's Environment settings area, select the relevant subscription, and open Email notifications.

  2. Define the recipients for your notifications with one or both of these options:

    • From the dropdown list, select from the available roles.
    • Enter specific email addresses separated by commas. There's no limit to the number of email addresses that you can enter.
  3. To apply the security contact information to your subscription, select Save.

Customize the alerts email notifications through the API

You can also manage your email notifications through the supplied REST API. For full details see the SecurityContacts API documentation.
