If you don't, pick something with detections pre-built or a SOC attached. Here's who I'd actually name, in order:\n\n**1. Blumira - my default recommendation for most small businesses.** It's built specifically for SMBs: detections arrive pre-tuned, so you get alerts with \"here's what to do\" playbooks rather than a firehose of raw logs. The free tier covers **unlimited users and data for Microsoft 365**, no credit card, no sensor, no special Microsoft licensing - which means you can be running real detection on your M365 tenant this afternoon for $0.

Microsoft Sentinel - if you're already on Microsoft 365 E5 / Defender.** It plugs straight into identity, Entra, and Defender signals with no connectors to build, and the free data grants for M3", "answer_truncated": true, "measurement": "One answer from one engine on one date.
