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

Brands named, in the order the engine gave

1. Blumira recommended
   Blumira - My default suggestion for a business without a dedicated security person.
2. Microsoft recommended
   Free tier covers Microsoft 365 if you just want to try it.
3. Microsoft 365 recommended
   Free tier covers Microsoft 365 if you just want to try it.
4. Microsoft Sentinel recommended
   Microsoft Sentinel - Best choice if you're already a Microsoft 365 Business Premium / E5 shop.
5. Sentinel recommended
   Microsoft Sentinel - Best choice if you're already a Microsoft 365 Business Premium / E5 shop.
6. Microsoft 365 Business recommended

7. Microsoft 365 Business Premium recommended
   Microsoft Sentinel - Best choice if you're already a Microsoft 365 Business Premium / E5 shop.
8. Entra ID recommended
   Connectors to Entra ID, Defender, and M365 are first-party and there's a free data grant for several M365 log types, so the marginal cost of covering your core identity surface is low.
9. Defender recommended
   Connectors to Entra ID, Defender, and M365 are first-party and there's a free data grant for several M365 log types, so the marginal cost of covering your core identity surface is low.
10. Huntress recommended
    Huntress Managed SIEM - Pick this if what you actually want is "someone else watches my logs 24/7." It's a managed service rather than a tool you operate, it bolts onto Huntress EDR/ITDR if you already run that, and the 24/7 human SOC is the product.
11. Wazuh recommended
    Wazuh - The open-source option, and the right answer if you have in-house Linux/infra skill and more time than budget.
12. Linux recommended
    Wazuh - The open-source option, and the right answer if you have in-house Linux/infra skill and more time than budget.
13. Graylog Security recommended
    Graylog Security (Small Business tier) - Good middle ground when your main pain is log search and retention rather than threat detection.
14. Rapid7 InsightIDR recommended
    Rapid7 InsightIDR - Worth a look if you want predictable per-asset pricing plus 24/7 MDR coverage from one vendor, and you're a bit bigger (50+ employees).

The answer, as recorded

Here's what I'd actually recommend, roughly in the order I'd consider them for a small business: **1. Blumira** - My default suggestion for a business without a dedicated security person. It's explicitly built for IT generalists: prepackaged detections, plain-English findings with remediation steps, and included SOC support rather than a blank query console you have to learn. Pricing is per-employee (roughly $12-21/employee/month) with unlimited data ingestion, which matters because the usual SIEM budget disaster is surprise log-volume overage. Free tier covers Microsoft 365 if you just want to try it. **2. Microsoft Sentinel** - Best choice if you're already a Microsoft 365 Business Premium / E5 shop. Connectors to Entra ID, Defender, and M365 are first-party and there's a free data grant for several M365 log types, so the marginal cost of covering your core identity surface is low. The catch is the per-GB consumption model (~$5/GB pay-as-you-go) and that it genuinely expects someone comfortable with KQL. Great with an MSP managing it, risky unmanaged. **3. Huntress Managed SIEM** - Pick this if what you actually want is "someone else watches my logs 24/7." It's a managed service rather than a tool you operate, it bolts onto Huntress EDR/ITDR if you already run that, and the 24/7 human SOC is the product. Less flexible, less tuning, far less work. **4. Wazuh** - The open-source option, and the right answer if you have in-house Linux/infra skill and more time than budget. Self-hosted is free with no ingestion metering, it bundles file-integrity monitoring and vulnerability detection, and it'll produce PCI/HIPAA/GDPR reports. Wazuh Cloud starts around $571/month for ~100 agents if you'd rather not run the stack. Be honest about the hidden cost: tuning and maintenance is real engineering time. **5. Graylog Security (Small Business tier)** - Good middle ground when your main pain is log search and retention rather than threat detection. Strong log management lineage, a tier priced specifically for SMBs, and a free open-source version to start on. **6. Rapid7 InsightIDR** - Worth a look if you want predictable per-asset pricing plus 24/7 MDR coverage from one vendor, and you're a bit bigger (50+ employees). More expensive than the above, more complete. Two practical notes: most "best SIEM" listicles, including several I hit above, are affiliate-driven, so treat the specific dollar figures as starting points and get quotes - Sentinel in particular can swing wildly with your log volume. And if you have fewer than ~25 employees, a well-configured EDR plus M365 audit logging often buys more real security than a SIEM does; SIEM starts paying off when you have compliance requirements or enough systems that correlation matters.
