11. Graylog mentioned
    Graylog Security - If your real need is log management and compliance evidence more than threat detection, Graylog is cheaper and less fussy than a full SIEM, with a free open-source edition.
12. Graylog Security mentioned
    Graylog Security - If your real need is log management and compliance evidence more than threat detection, Graylog is cheaper and less fussy than a full SIEM, with a free open-source edition.

14. Arctic Wolf mentioned
    A lot of small businesses that ask for SIEM are actually better served by MDR (Huntress, Arctic Wolf, Blumira's higher tiers) - a SIEM that nobody reads is just an expensive log archive.

The answer, as recorded

Here's what I'd actually recommend, roughly in the order I'd consider them for a small business: ## Top picks **1. Blumira** - My default recommendation for most small businesses. It's purpose-built for lean/no-dedicated-security IT teams: deploys in hours, ships with pre-tuned detections (so you're not writing correlation rules), and prices **per employee with unlimited log ingestion** (~$12-21/user/month depending on tier), which means no bill shock when logging grows. There's also a free tier for Microsoft 365. The main catch is that per-user pricing gets expensive if you have lots of employees but few log sources. **2. Huntress Managed SIEM** - Best if you want someone else watching the alerts. Huntress is essentially an SMB-focused managed security company; their 24/7 SOC triages and tells you what to actually do. Especially compelling if you already run Huntress EDR, since it's one console and one vendor. Pricing is quote-based, per data source. **3. Microsoft Sentinel** - The obvious choice *if* you're already Microsoft 365 E5 / Azure-heavy. Microsoft 365 and Entra ID logs ingest free, integration is native, and it's genuinely enterprise-grade. Two caveats: per-GB pricing (~$2.50-5/GB) is unpredictable if you pipe in firewall or network logs, and you need someone comfortable with KQL. Not a "set it and forget it" tool. **4. Wazuh** - The right answer if you have technical staff and more time than budget. Free and open source, covers SIEM + XDR + file integrity monitoring + compliance reporting (PCI, HIPAA, CIS). Genuinely capable. But you're the one doing deployment, tuning, storage sizing, and alert triage - budget real engineering hours, or buy Wazuh Cloud (from ~$571/mo for 100 agents). ## Worth a look depending on situation **5. Rapid7 InsightIDR** - Priced per monitored asset rather than per GB, so costs stay predictable. Good for the upper end of "small business" (100-500 seats), and you can bolt on their MDR service for 24/7 coverage. **6. Graylog Security** - If your real need is *log management and compliance evidence* more than threat detection, Graylog is cheaper and less fussy than a full SIEM, with a free open-source edition. **7. CrowdStrike Falcon Next-Gen SIEM** - Only if you're already a Falcon customer; then endpoint data flows in free and it's an easy add. Otherwise overkill on price for this segment. ## One honest caveat A lot of small businesses that ask for SIEM are actually better served by **MDR** (Huntress, Arctic Wolf, Blumira's higher tiers) - a SIEM that nobody reads is just an expensive log archive. If you don't have someone who will look at alerts daily, prioritize the managed options (#1, #2) over the DIY ones (#3, #4). And if you're buying primarily to satisfy a compliance requirement (SOC 2, CMMC, cyber insurance), say so to the vendor up front - retention terms and report templates matter more than detection quality in that case. Pricing figures above are list/approximate from the sources below and move around; get quotes for your actual seat and log-source count.
