This is a searchable reference of documented Microsoft Defender for Cloud
security alerts. The alerts shown here are only those Microsoft publicly documents on
Microsoft Learn. This list is not exhaustive — the platform may generate
additional alerts and detections that are not documented here.
For example, some recently added alerts powered by Microsoft Defender Threat Intelligence
and Microsoft Defender for Endpoint (MDE) may be undocumented. This applies to several
Defender plans, including App Service which is backed by MDE detections.
Data is scraped from official Microsoft Learn documentation. Alerts marked as
"archive" were sourced from deprecated/archived pages and may no longer
be actively documented by Microsoft. Some of these archive alerts may themselves be
deprecated — they are included for reference but may no longer be generated by
Defender for Cloud.
Defender for Containers (archive) alerts are sourced from an offline
snapshot of the former containers alert reference page. These alert types are no longer
actively documented because Microsoft is transitioning to MDE-based alert correlation for
container security. However, these alerts may still be detected even though they are no
longer listed in the official documentation.
Defender for App Service (archive) alerts are sourced from an offline
snapshot of the former App Service alert reference page. The current Microsoft Learn page
no longer documents these alerts. However, they may still be detected by Defender for
Cloud, particularly as App Service is backed by MDE-based detections.
Defender for DNS alerts are part of Defender for Servers P2
and are only available when the Defender for Servers P2 plan is enabled.
Observed alerts are real alerts detected in the
maintainer's own Azure lab environment.
These alerts are grounded from actual detections — they may not be officially documented
on Microsoft Learn but are real alerts generated by Microsoft Defender for Cloud.
They are included here for reference alongside the documented alerts.
