The question asked, verbatim: best siem software for small businesses

Brands named, in the order the engine gave

1. Blumira recommended
   Blumira - my default recommendation for a small business with no security staff
2. Huntress mentioned
   Huntress Managed SIEM - best if you want humans watching, or already use Huntress EDR
3. Huntress Managed EDR mentioned
   If you already run Huntress Managed EDR ($8.99/endpoint list), adding SIEM is the lowest-friction upgrade available.
4. Microsoft Sentinel mentioned
   Microsoft Sentinel - only if you're already a Microsoft 365 E5 / Defender shop
5. Sentinel mentioned
   Microsoft Sentinel - only if you're already a Microsoft 365 E5 / Defender shop
6. Microsoft 365 mentioned
   Microsoft Sentinel - only if you're already a Microsoft 365 E5 / Defender shop
7. Defender mentioned
   Microsoft Sentinel - only if you're already a Microsoft 365 E5 / Defender shop
8. Entra ID mentioned
   Connectors to Entra ID, Defender, and Office are first-party and free-ish to ingest, which changes the math entirely.
9. Wazuh mentioned
   Wazuh - the right answer if you have real Linux/ops skill in-house
10. Linux mentioned
    Wazuh - the right answer if you have real Linux/ops skill in-house
11. ManageEngine EventLog Analyzer mentioned
    ManageEngine EventLog Analyzer - cheapest path to "check the compliance box"
12. Graylog mentioned
    Graylog - if your real problem is log management, not detection
13. Graylog Open mentioned
    Graylog Open is permanently free with no ingest cap (source-available under SSPL).
14. Graylog Security mentioned
    Note that Graylog Security, the tier that adds actual SIEM detection content, starts around $15,000/year - well past small-business territory.
15. Rapid7 InsightIDR mentioned
    Rapid7 InsightIDR and Sumo Logic show up at the top of most listicles and are good products, but I'd put them at the upper end of "small business" - InsightIDR's asset-based pricing plus bundled MDR is worth a quote if you're 200+ seats.
16. Sumo Logic mentioned
    Rapid7 InsightIDR and Sumo Logic show up at the top of most listicles and are good products, but I'd put them at the upper end of "small business" - InsightIDR's asset-based pricing plus bundled MDR is worth a quote if you're 200+ seats.

The answer, as recorded

Here's how I'd actually rank these for a small business, roughly in the order I'd suggest you evaluate them: ## 1. Blumira - my default recommendation for a small business with no security staff Flat pricing per employee (~$12/user/mo for the SIEM starter tier, ~$16 for SIEM+) with **unlimited data ingestion**, which is the single biggest thing that matters at your size. Almost every SIEM horror story is a per-GB bill that exploded. Blumira also ships prebuilt detections and a SOC to call, so you're not writing correlation rules yourself. Weakness: it's a shallower platform than the enterprise tools - fine, because you don't need depth, you need alerts that are real. ## 2. Huntress Managed SIEM - best if you want humans watching, or already use Huntress EDR Published list is **$4.00/data source/mo** on a 12-month term with a 50-unit minimum, and MSPs get it cheaper. The 24/7 SOC is the product; the SIEM is the data layer. If you already run Huntress Managed EDR ($8.99/endpoint list), adding SIEM is the lowest-friction upgrade available. Known gripes: reporting and API access are thin, and it strains in multi-site/high-log-volume setups. ## 3. Microsoft Sentinel - only if you're already a Microsoft 365 E5 / Defender shop Connectors to Entra ID, Defender, and Office are first-party and free-ish to ingest, which changes the math entirely. But pay-as-you-go is **$5.20/GB**, and a small business at 10 GB/day lands near **$1,290/mo** - and that's before someone tunes it. Great if you have an MSP managing it, a money pit if nobody owns cost control. ## 4. Wazuh - the right answer if you have real Linux/ops skill in-house Free and open source, and genuinely capable: log collection, file integrity monitoring, vulnerability detection, and endpoint agents in one. Their managed cloud starts around $571/mo for up to 100 agents. The catch is honest and unavoidable - you are the SOC. If nobody on your team wants to maintain it, you'll end up with an expensive-in-hours system nobody reads. ## 5. ManageEngine EventLog Analyzer - cheapest path to "check the compliance box" Consistently the low-cost option, strong on Windows/AD log analysis and audit reporting. Pick it if the driver is an auditor, a cyber-insurance questionnaire, or a contract requirement rather than active threat detection. ## 6. Graylog - if your real problem is log management, not detection **Graylog Open** is permanently free with no ingest cap (source-available under SSPL). Use it to centralize and search logs. Note that **Graylog Security**, the tier that adds actual SIEM detection content, starts around **$15,000/year** - well past small-business territory. Rapid7 InsightIDR and Sumo Logic show up at the top of most listicles and are good products, but I'd put them at the upper end of "small business" - InsightIDR's asset-based pricing plus bundled MDR is worth a quote if you're 200+ seats. **Two caveats.** A lot of the "best SIEM 2026" pages are affiliate-driven and rank by referral fees, so treat their ordering as noise. And more importantly: a SIEM without someone reading it is a log archive with a subscription fee. If you can only fund one thing, fund managed detection (Huntress, or Blumira's higher tier) over a self-run SIEM.
