The answer, as recorded

The honest starting point: a SIEM is only as good as the person reading the alerts. If nobody on staff will triage alerts at 2am, buy something with humans attached, not a log search tool. Here's how I'd rank them for a small business: **1. Blumira** - My default recommendation for a small business with no security team. It's built specifically for SMBs: deploys in hours, ships with pre-tuned detection rules so you're not writing correlation logic, and every finding comes with plain-English remediation steps. Priced per employee (roughly $12-21/user/month depending on tier) rather than per GB ingested, which means your bill doesn't explode the month you turn on verbose logging. There's also a genuinely usable free tier for Microsoft 365 logs. **2. Huntress Managed SIEM** - Pick this if you want a real SOC watching, not just software. Huntress's whole model is a 24/7 human SOC that only escalates things that matter, so alert fatigue stays low. It costs more and pricing is quote-only, but for a 20-100 person company with zero security staff, the managed piece is the entire value. Their endpoint product is well-regarded in the SMB/MSP world and the SIEM plugs into it. **3. Microsoft Sentinel** - The right answer if you're already deep in Microsoft 365 E5 / Entra ID / Azure. Connectors to Microsoft sources are free or heavily discounted, and you avoid buying a second vendor. Caveats: it's consumption-priced per GB ingested (~$2.50-5.20/GB), so costs are unpredictable, and it's a build-it-yourself platform. Budget for a consultant or an MSSP to set it up. **4. Wazuh** - The choice if you have technical talent and a tight budget. Open source and free to self-host, covering file integrity monitoring, vulnerability detection, and compliance mapping (PCI, HIPAA) out of the box. The catch is that "free" means you're paying in engineering hours - expect meaningful setup and ongoing tuning. Their managed cloud starts around $571/month if you'd rather not run it yourself. **5. ManageEngine EventLog Analyzer** - Worth a look if your need is mostly compliance reporting and Windows/AD log retention rather than active threat hunting. Cheap, on-prem or cloud, perpetual license option. Less impressive as a detection engine. I'd skip Splunk, Sumo Logic, and Elastic Security for a genuinely small business despite them showing up on "best of" lists - they're excellent platforms priced and engineered for teams that have a dedicated analyst. Sumo's list price of ~$270/GB/month tells you who the target customer is. One practical note: if you're buying SIEM to satisfy a cyber-insurance questionnaire or a SOC 2 audit, check the exact control wording first. Several of these (especially Wazuh and EventLog Analyzer) satisfy log retention requirements at a fraction of the cost of a full detection platform.
