Microsoft Defender for Cloud

A tool that strengthens security posture and protects workloads across Azure, hybrid, and multicloud.

Microsoft Defender for Cloud is a cloud-native application protection platform that continuously monitors Azure, on-premises, and multicloud environments for misconfigurations and active threats. It produces a Secure Score — a numeric measure of current security posture — and surfaces prioritized recommendations to close gaps, making it the primary tool for gauging how hardened an Azure environment is. A common exam confusion is treating it as a SIEM or log-analytics tool; that role belongs to Microsoft Sentinel. Defender for Cloud focuses on posture management and workload protection (servers, containers, databases), while Sentinel handles threat detection and incident response across collected log data.
