Description:
This setting makes sure that all Owner role users automatically receive security alert emails. Turning it on ensures that subscription owners are notified about important security issues without needing to add their emails manually.
Rationale:
Sending security alerts to all users with the Owner role ensures that the people responsible for managing the subscription are immediately aware of important security issues. This improves response time and helps prevent security risks from being overlooked.
Impact:
Enabling this setting may result in more alert emails being sent to subscription owners, which could lead to notification fatigue. However, this is outweighed by the benefit of ensuring that critical security issues are not missed.
Default Value:
By default, this setting is disabled (notifications to users with the Owner role are not automatically enabled).
Pre-requisites:
A valid security contact email must be configured in Microsoft Defender for Cloud before enabling notifications for users with the Owner role.
