Ensure That 'Notify about alerts with the following severity' is Set to 'High'
Why This Matters
Without high-severity alert notifications enabled, critical security incidents detected by Microsoft Defender for Cloud may go unnoticed by the subscription owner or designated security contacts. Delayed awareness of severe threats such as unauthorized access or privilege escalation increases the risk of breach escalation and data loss. Configuring this setting ensures your incident response team receives timely notifications for high-severity alerts.
What Aether365 Checks
Aether365 verifies that the "Notify about alerts with the following severity" setting is enabled and configured to "High" or higher for your Azure subscription. This check appears in your Aether365 dashboard under azure-subscription-security checks.
