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 most small businesses.
2. Microsoft compared
   Microsoft Sentinel - If you're already on Microsoft 365 Business Premium or E5, this is almost always the cheapest path, because M365/Entra/Defender logs ingest free and commitment tiers drop the rate to roughly $2-3/GB vs ~$5.22 pay-as-you-go.
3. Microsoft Sentinel compared
   Microsoft Sentinel - If you're already on Microsoft 365 Business Premium or E5, this is almost always the cheapest path, because M365/Entra/Defender logs ingest free and commitment tiers drop the rate to roughly $2-3/GB vs ~$5.22 pay-as-you-go.
4. Sentinel compared
   Microsoft Sentinel - If you're already on Microsoft 365 Business Premium or E5, this is almost always the cheapest path, because M365/Entra/Defender logs ingest free and commitment tiers drop the rate to roughly $2-3/GB vs ~$5.22 pay-as-you-go.

9. Huntress mentioned
   Huntress - Not a traditional SIEM, but for a lot of small businesses it's the better buy: EDR plus a human-led SOC at predictable per-endpoint pricing, and they've added SIEM/log features.
10. Wazuh mentioned
    Wazuh - The right answer if you have genuine in-house Linux/sysadmin skill and a tight budget.
11. Linux mentioned
    Wazuh - The right answer if you have genuine in-house Linux/sysadmin skill and a tight budget.
12. Rapid7 InsightIDR mentioned
    Rapid7 InsightIDR - Worth a quote if you want SIEM plus MDR from one vendor.
13. Sumo Logic mentioned
    First, some of the "best SIEM" listicles you'll hit are affiliate-driven and their numbers don't survive contact with a vendor quote - one in my results listed Sumo Logic at $270/GB/month, which is not a real small-business price.

The answer, as recorded

For a small business, the real constraint isn't features - it's that nobody on staff has time to tune rules or triage alerts at 2am. So I'd weight heavily toward managed/low-maintenance options: **1. Blumira** - My default recommendation for most small businesses. Per-employee pricing (~$12-21/employee/month) with unlimited data ingestion, which is a huge deal because per-GB pricing is how SIEM bills quietly explode. It ships with pre-tuned detections and actual humans you can call, so you're not building a rule library from scratch. There's a free tier to try it. ([blumira.com/siem-cost](https://www.blumira.com/siem-cost)) **2. Microsoft Sentinel** - If you're already on Microsoft 365 Business Premium or E5, this is almost always the cheapest path, because M365/Entra/Defender logs ingest free and commitment tiers drop the rate to roughly $2-3/GB vs ~$5.22 pay-as-you-go. Caveat: it's a build-it-yourself platform. Budget for a partner/MSP to configure it, or it becomes an expensive log bucket nobody reads. ([siemcostcalculator.com/siem-pricing-comparison](https://siemcostcalculator.com/siem-pricing-comparison)) **3. Huntress** - Not a traditional SIEM, but for a lot of small businesses it's the better buy: EDR plus a human-led SOC at predictable per-endpoint pricing, and they've added SIEM/log features. If your goal is "someone competent is watching," this beats owning a SIEM you can't staff. ([connectwise.com/blog/best-siem-software-solutions](https://www.connectwise.com/blog/best-siem-software-solutions)) **4. Wazuh** - The right answer if you have genuine in-house Linux/sysadmin skill and a tight budget. Self-hosted is free and legitimately capable (FIM, vuln detection, compliance reporting); Wazuh Cloud starts around $571/month for ~100 agents. The cost is your time - expect real effort on deployment and tuning. ([alekseialeinikov.com](https://www.alekseialeinikov.com/en/blog/topics/security/siem-pricing-wazuh-vs-sentinel-vs-google-secops-2026)) **5. Rapid7 InsightIDR** - Worth a quote if you want SIEM plus MDR from one vendor. Priced per monitored asset rather than data volume, so costs stay predictable, and 24/7 SOC coverage is bundled. Generally a step up in price from the above. ([paloaltonetworks.com/cyberpedia/siem-tools-comparison](https://www.paloaltonetworks.com/cyberpedia/siem-tools-comparison)) **Who I'd skip:** Splunk and similar enterprise-tier platforms. Excellent products, but the per-GB economics (often cited near $1,000/GB/day-class list pricing) and the operational overhead don't make sense below a few hundred employees. ([siemcostcalculator.com](https://siemcostcalculator.com/)) Two notes on the shopping process. First, some of the "best SIEM" listicles you'll hit are affiliate-driven and their numbers don't survive contact with a vendor quote - one in my results listed Sumo Logic at $270/GB/month, which is not a real small-business price. Get quotes directly. Second, whatever you pick, decide *before* you buy who reads the alerts. If the honest answer is "nobody," buy managed detection (Blumira or Huntress) rather than a SIEM.
