Overall, my experience with Microsoft Defender for Cloud has been positive. It's been very effective in delivering a unified view of my security posture across multiple clouds (AWS/GCP/Azure). However, the cost was surprisingly high and the analytics could leave much to be desired from a visual standpoint. Despite this, it helped us improve compliance and streamline an overabundance of tooling that we had.

Like many MS tools, they have too many UI's that you need to navigate to for accessing data. You get an alert and then have to click multiple times to get any actionable details, if you want to explore more pieces you have to load up another dashboard. Loads of false positives so alert fatigue is a thing.
