Blumira** - This is my default recommendation for most small businesses. It's the one SIEM actually designed around the constraint that you don't have a security analyst on staff. Per-user pricing (~$12-21/user/month depending on tier) instead of per-GB means your bill doesn't explode when you turn on more logging, which is the single most common way small companies get burned by SIEM. Detections ship pre-tuned, and alerts come with written response steps rather than a raw event you have to interpret. There's also a free tier for M365/Google Workspace logging that's a legitimate starting point. ([Blumira pricing/positioning](https://www.blumira.com/arcticwolf), [MSP Compared](https://mspcompared.com/blumira/alternatives/))\n\n**2. Microsoft Sentinel** - Best choice *if* you're already a Microsoft 365 E5 / Defender shop. Defender XDR alerts and raw data, Entra ID Protection alerts, Azure Activity, and O365 audit logs ingest **free**, plus a 5 MB/user/day grant with E5. That can make the effective cost near-zero for the logs you care about most. The catch: Sentinel is a build-it-yourself SIEM.
