Why Microsoft Defender for Cloud in Azure? - Purpose & Use Cases

The Big Idea

What if your cloud could watch itself for threats while you focus on your work?

The Scenario

Imagine you have many servers and apps running in the cloud, and you try to watch over their security by checking each one manually every day.

You write down notes, look for problems, and try to remember if anything unusual happened.

The Problem
