Exploring Use Cases for Microsoft Defender for Cloud

Microsoft Defender for Cloud is a cloud-native security solution that strengthens your Azure environment by combining proactive recommendations with reactive incident management. In this guide, we’ll cover its two primary use cases—Incident Management and Security Optimization—along with core components that power these scenarios.

Key Use Cases

Incident Management: A structured response cycle to detect, assess, and remediate threats.
Security Optimization: Continuous policy enforcement and actionable recommendations to harden your environment.

1. Incident Management

Microsoft Defender for Cloud provides a repeatable cycle to handle security incidents from detection to closure.

1.1 Detect

Verify that a high-severity security alert has been generated in the Azure portal or exported to your SIEM.

1.2 Assess

Collect detailed information about the alert, including affected resources, timeline, and potential impact.

1.3 Diagnose

Follow the remediation steps recommended by the alert. Common actions include isolating compromised resources, rotating credentials, and applying patches.

1.4 Stabilize and Close

Confirm that the threat has been neutralized, apply any remaining mitigations, then officially close the incident.

Note

Enable continuous export of security alerts to integrate Defender for Cloud with your SIEM or ITSM workflows.

2. Security Optimization

Security Optimization in Defender for Cloud helps you establish a strong security baseline and continuously reinforce it:
