Which Microsoft Defender for Cloud metric displays the overall security health of an Azure subscription?

The metric that displays the overall security health of an Azure subscription is the secure score. This score provides a quantifiable assessment of how well your environment aligns with security best practices. It is a numerical representation that reflects your security posture, based on the security settings and configurations implemented across your Azure resources.

The secure score takes into account various factors, including the application of security controls, the extent of vulnerabilities, and compliance with recommended practices. As you make improvements to your security configurations, your secure score increases, effectively helping you to identify and prioritize areas that need attention.

Through this score, organizations can measure their security progress over time and gain insight into how effectively their security controls are functioning, making it a crucial metric for assessing overall security health in Azure. This emphasizes the importance of actively managing and improving security measures within the subscription to achieve a higher secure score.
