## Our take

What our shortlists say about each one.

### [Microsoft Defender for Identity](https://cybersectools.com/tools/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.

### [Proofpoint Identity Threat Defense](https://cybersectools.com/tools/proofpoint-identity-threat-defense)

Best for: Companies wanting to find and close attack paths

Proofpoint earns its spot for teams that want to shrink the attack surface first, because it shows the shortest routes to your critical assets and helps close them. Its decoys need no agents, which keeps rollout light. It is built for mid-size and large Microsoft estates, so check coverage if you also run another identity provider.
