Features, integrations, deployment and the company behind each one, side by side. ## Our take What our shortlists say about each one. ### [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.

That fits mid-market and enterprise teams with heavy event volumes. Vista Equity Partners has owned Securonix since 2022, so ask how the ThreatQuotient platform will merge into the main product.
