The answer, as recorded

Short version up front: most small businesses are better served by a SIEM that comes with detections and someone watching it than by a raw log platform. Here's who I'd actually name, in order: **1. Blumira** - My default recommendation for a 10-250 person company with no security analyst. It's built for SMBs: cloud deploy in hours, detections come pre-tuned (you aren't writing correlation rules), and alerts arrive with plain-language response playbooks. Pricing is per-user (~$12/user/month at entry tier), so your bill doesn't explode when logging volume spikes - which is the single biggest budget trap in this category. There's a genuinely usable free tier (3 cloud integrations, 14-day retention) to test with. ([Blumira pricing/comparison](https://blumira.com/hubfs/Microsoft-Sentinel-vs.-Blumira-Updated.pdf?hsLang=en), [G2 comparison](https://www.g2.com/compare/blumira-automated-detection-response-vs-microsoft-sentinel)) **2. Microsoft Sentinel** - The right answer *if* you're already Microsoft 365 E5/Business Premium and have someone with Azure skills. Native connectors to Entra ID, Defender, and Exchange mean your highest-value logs are a few clicks away, and E5 customers get a meaningful free M365 data grant. Two caveats: pricing is per-GB ingested (~$2.46/GB pay-as-you-go), so costs are hard to forecast, and realistically it takes 1-2 dedicated people to run well. Not a fit if nobody owns it. ([Wazuh vs Sentinel](https://www.selecthub.com/siem-tools/wazuh-vs-microsoft-sentinel/), [pricing comparison](https://costbench.com/software/siem/)) **3. Wazuh** - The pick when budget is near zero and you have genuine Linux/ops capability in-house. Open source and free for the self-hosted version, and it's more than a SIEM - file integrity monitoring, vulnerability detection, and endpoint agents included, which covers several PCI/HIPAA control requirements at once. You pay in engineering time instead of license fees; expect real effort to deploy and tune. Wazuh Cloud exists with custom pricing if you want the hosted version. ([Wazuh vs Sentinel](https://www.selecthub.com/siem-tools/wazuh-vs-microsoft-sentinel/)) **4. Huntress Managed SIEM** - Worth naming because many small businesses already run Huntress for endpoint/ITDR, and bolting SIEM onto that gives you one vendor, one agent, and a human SOC triaging alerts overnight. If you want "I don't want to look at a dashboard," this and Blumira are the two to shortlist. **5. Arctic Wolf** - Co-managed SIEM/MDR with a named concierge security team. More expensive and a longer contract than the others, but it's the one I'd name if you're a small business under real compliance or cyber-insurance pressure and need an auditable answer to "who monitors your logs 24/7." Usually overkill under ~50 employees. **6. Elastic Security** - Honorable mention for value and flexibility (free self-managed tier, cloud from roughly $95/month per resource). Strong if you already run the Elastic stack for application logs. Otherwise the detection engineering burden lands on you. ([Costbench roundup](https://costbench.com/best/siem-for-small-business/)) Two things I'd flag regardless of choice: ingest only your high-signal sources first (identity, endpoint, firewall, email) rather than everything - volume is what kills SMB SIEM budgets and buries real alerts. And check your retention requirement before you sign; 14-30 days is fine operationally but often fails compliance, and extending it is where vendors make their margin. One note on sourcing: the "best SIEM 2026" roundup sites above are affiliate-driven and their rankings (e.g. Sumo Logic as #1 for small business, at $270/GB/month) don't match what small businesses actually deploy - I used them for pricing data points, not for the ordering.
