## The answer, as recorded

Asked on 2026-10-06 through Claude (Anthropic) with web search (model claude-opus-5).

> ## My short answer
> 
> For most small businesses, **Blumira** - it's the one I'd actually set up first.
> 
> **1. Blumira** - Purpose-built for SMBs with little or no security staff. Flat per-user pricing (~$12/user/mo SIEM Starter, $16 SIEM+, $21 XDR), and critically: **unlimited data ingestion, 365-day retention, and 24/7 SecOps support included**. That pricing model matters more than any feature list - per-GB SIEMs punish you for logging more, which is exactly the wrong incentive when you're small. Detections ship pre-tuned with written response playbooks, so you don't need an analyst to interpret alerts.

> 
> **2. Microsoft Sentinel** - The right pick *if* you're a Microsoft 365 E5/Business Premium shop. The reason is narrow but decisive: **Defender XDR data ingested into Sentinel is free** (Defender for Endpoint, Office 365, Identity, Cloud Apps), so your most valuable logs cost nothing. Pay-as-you-go beyond that runs ~$5.20/GB, which at 10 GB/day is ~$1,560/mo - so it's cheap if Defender is most of your footprint and expensive the moment it isn't. Needs someone comfortable in
