- Microsoft Defender for Identity
Best for: Microsoft shops with on-premises Active Directory
It leads this list because most companies still run on-premises Active Directory, and this product watches it from the inside while feeding the same Defender incidents your analysts already work. If you are a Microsoft shop, it is often the shortest path to identity detection. If your endpoint and SOC stack is not Microsoft, weigh how much of that value carries over.

- Zscaler Identity Protection
Best for: Zscaler customers wanting identity risk checks
It belongs on this list if you already run Zscaler, because it switches on in the agent your devices already run and can contain an attack through the access rules you already enforce. It also helps you fix Active Directory risks with step-by-step scripts. Outside Zscaler, it has little reason to be your first choice.
