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 genuine SMB with no security team.
2. Microsoft 365 mentioned
   There's also a free tier for Microsoft 365 that's a legitimate starting point.
3. Huntress mentioned
   Huntress Managed SIEM - Best pick if you already use or are considering Huntress for endpoint protection.
4. Microsoft Sentinel mentioned
   Microsoft Sentinel - Right answer if you're deep in Microsoft 365 E5/Defender, because much of that telemetry ingests free and you get it via the Defender portal.
5. Sentinel mentioned
   Microsoft Sentinel - Right answer if you're deep in Microsoft 365 E5/Defender, because much of that telemetry ingests free and you get it via the Defender portal.
6. Defender mentioned
   Microsoft Sentinel - Right answer if you're deep in Microsoft 365 E5/Defender, because much of that telemetry ingests free and you get it via the Defender portal.
7. ManageEngine Log360 / EventLog Analyzer mentioned
   ManageEngine Log360 / EventLog Analyzer - The pragmatic compliance answer.
8. Wazuh mentioned
   Wazuh - The open-source option, and the best value if and only if you have someone who genuinely enjoys Linux administration.
9. Linux mentioned
   Wazuh - The open-source option, and the best value if and only if you have someone who genuinely enjoys Linux administration.
10. Rapid7 InsightIDR mentioned
    Rapid7 InsightIDR - Step up when you've outgrown SMB tooling and want asset-metered pricing plus managed SOC coverage.
11. Sumo Logic mentioned
    Worth skipping at your size: Splunk and Sumo Logic.
12. Google recommended
    If you tell me your headcount and whether you're Microsoft- or Google-centric, the list collapses to one or two - but absent that, start with Blumira's free M365 tier and see whether the alert volume is something you can actually act on.

The answer, as recorded

# SIEM for small businesses Honest framing first: for most small businesses, the real question isn't "which SIEM" but "who watches the alerts at 2am." A SIEM you don't staff is just an expensive log bucket. So the top of my list is weighted toward tools that include detection content and human monitoring rather than raw platforms. **1. Blumira** - My default recommendation for a genuine SMB with no security team. Per-employee pricing (Detect edition starts around $12/employee/month), so your bill doesn't explode when someone turns on verbose logging. Ships with prewritten detections and automated response instead of expecting you to author rules. There's also a free tier for Microsoft 365 that's a legitimate starting point. **2. Huntress Managed SIEM** - Best pick if you already use or are considering Huntress for endpoint protection. Priced per *data source* (~$4/source/month at published rates, less through MSPs), which is far easier to forecast than per-GB. Their 24/7 SOC is the actual product; the SIEM is the telemetry layer. Strong choice for businesses that want someone else on call. **3. Microsoft Sentinel** - Right answer if you're deep in Microsoft 365 E5/Defender, because much of that telemetry ingests free and you get it via the Defender portal. Otherwise be careful: pay-as-you-go is ~$4.30/GB, and 30GB/day works out to roughly $3,900/month. Powerful, but it will happily bankrupt a 40-person company that logs everything. **4. ManageEngine Log360 / EventLog Analyzer** - The pragmatic compliance answer. If your driver is an auditor asking for log retention and reporting (PCI, HIPAA, SOC 2) rather than active threat hunting, this is cheap, on-prem-capable, perpetual-license, and does the reports. Interface is dated; capability is adequate. **5. Wazuh** - The open-source option, and the best value *if and only if* you have someone who genuinely enjoys Linux administration. Free license, but you pay in engineering hours for tuning, scaling, and writing your own detections. Great for a technical founder or a lean IT shop; a trap for everyone else. **6. Rapid7 InsightIDR** - Step up when you've outgrown SMB tooling and want asset-metered pricing plus managed SOC coverage. More capable than Blumira, correspondingly more expensive and more to operate. **Worth skipping at your size:** Splunk and Sumo Logic. Both are excellent products with consumption pricing (Sumo credits ~$1.50 MSRP) that punishes unpredictable log volume - the exact thing small businesses can't forecast. If you tell me your headcount and whether you're Microsoft- or Google-centric, the list collapses to one or two - but absent that, start with Blumira's free M365 tier and see whether the alert volume is something you can actually act on. That answer tells you whether you need a tool or a service.
