- 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.

- Semperis Identity Resilience Platform
Best for: Organizations where Active Directory recovery is a board-level risk
Semperis is hybrid-deployable and fits mid-market and enterprise. Its distinguishing capability is recovery: when ransomware takes the directory down, this is the product that brings it back. Pair it with an inline detection product if you also need to stop logins in real time.
