## Our take

What our shortlists say about the one we picked.

### [Microsoft Sentinel](https://cybersectools.com/tools/microsoft-sentinel)

Best for: Companies already running Microsoft

It earns its place because SIEM, SOAR, behavior analytics and a data lake come as one cloud service, so you do not stitch them together yourself. That suits any size, from SMB to enterprise, and it is the natural pick if Defender already runs your endpoints. If most of your stack is not Microsoft, check which of your key sources sit among the 350 connectors before you commit.
