### [Microsoft Defender for Cloud](https://cybersectools.com/tools/microsoft-defender-for-cloud)

Best for: Companies running mostly on Azure

Defender for Cloud earns a spot because it puts posture, compliance tracking, attack paths and workload protection for Azure, AWS and Google Cloud in one place, and Secure Score gives you an ordered list of fixes. It is aimed at mid-market and enterprise estates. The protection plans are separate for servers, containers, databases, storage and APIs, so decide which ones you need before you compare it with the rest.
