## Our take

What our shortlists say about the one we picked.

### [SentinelOne Singularity Identity Security](https://cybersectools.com/tools/sentinelone-singularity-identity-security)

Best for: SentinelOne customers adding identity protection

Singularity Identity is here because it adds decoys and leaked-credential checks on top of detection, which gives you early warning before an attacker reaches a domain controller. It makes most sense if SentinelOne already runs on your endpoints. Ask what the full feature set takes to switch on beyond the base deployment, so you budget for it up front.
