The answer, as recorded

# SIEM for small businesses The honest framing first: for a small business, the deciding factor usually isn't the detection engine - it's whether somebody is actually going to read the alerts. That pushes most small shops toward managed or heavily opinionated options rather than classic SIEM platforms. Here's who I'd actually name, in order: **1. Blumira** - My default recommendation for a small business with no dedicated security staff. It's built for the SMB case specifically: pre-tuned detections (so you're not writing correlation rules), plain-English response playbooks attached to each finding, and a real human SOC you can call. Pricing is per-employee rather than per-gigabyte, which matters enormously because per-GB pricing punishes you unpredictably as you add log sources. SIEM Starter runs about $12/employee/month, SIEM+ $16, full XDR $21, and there's a genuinely useful free tier (3 cloud integrations, 14-day retention) you can pilot with. About 38% of its review base is small business - it's the segment it's designed around. **2. Huntress Managed SIEM** - The strongest pick if you're already a Huntress EDR customer, or if you want the log side fully hands-off. List price is roughly $4 per data source per month with a 10 GB pooled allowance per source - predictable in a way almost nothing else in this category is. The "Smart Filtering" approach drops low-value log noise before it bills you. Caveat: Huntress skews toward MSPs and the larger end of small business, and the EDR product carries a 50-seat floor, so a 10-person company may find the overall package awkward. **3. Microsoft Sentinel** - The right answer if you're a Microsoft 365 E5 / Defender shop. The integration with Entra ID, Defender, and Azure logs is unmatched, and E5 licensing includes a meaningful free data grant for M365 logs, which can make it effectively cheap for your most important sources. But it is pay-as-you-go at roughly $2.46/GB ingested, and it's a platform, not a product - expect to build or buy workbooks, analytics rules, and someone's time to maintain them. Only pick this if you have a technical person who wants to own it. **4. Wazuh** - The choice when the budget is genuinely near zero and you have in-house Linux/ops skill. It's free and open source, with real capability (file integrity monitoring, vulnerability detection, log analysis, agent-based collection). The cost is entirely in your time: you host it, you tune it, you watch it. For a business with a competent sysadmin who enjoys this work, it's excellent value. For one without, it becomes shelfware fast. **5. Elastic Security** - Worth a look if you already run Elasticsearch for logs or application telemetry; it layers detection onto infrastructure you're paying for anyway. Roughly $95-$175/month per resource. Same caveat as Sentinel, more so: it expects engineering attention. **6. Sumo Logic** - Some roundups rank it first for SMB on breadth and usability, and it's cloud-native with a free tier. I'd put it lower for small business because its per-GB pricing scales steeply (published rates run up to the high hundreds per GB/month at premium tiers), which is the exact cost profile a small business should avoid. **What I'd skip:** Splunk, QRadar, and ArcSight. All capable, all priced and staffed for enterprise. **Practical path:** start with Blumira's free tier against your most important sources (M365, firewall, domain controllers). It costs nothing to find out whether per-employee managed SIEM fits you, and if it does, you're already deployed. If you're heavily Microsoft-licensed with E5, price Sentinel in parallel - the included data grant sometimes makes it the cheaper real answer. One thing worth noting: several of the comparison and pricing sites below are affiliate-funded aggregators, and their rankings should be read with that in mind. I'd weight vendor documentation and your own trial over any roundup, including this one.
