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

Brands named, in the order the engine gave

1. Sumo Logic mentioned
   Searched - quick caveat on what's out there: a lot of the top-ranking "best SIEM for small business 2026" listicles are affiliate/aggregator pages, and some of their picks are absurd for a genuinely small company (one ranks Sumo Logic #1 at $270/GB/month and IBM QRadar #2 at "$5,000-$250,000/year").
2. IBM mentioned

3. Blumira recommended
   Blumira - my default recommendation for a small business.
4. you're mentioned
   It's the one SIEM built for companies without a security team: cloud-native, pre-tuned detections so you're not writing correlation rules, 24/7 support, and per-employee pricing (~$12/employee/mo Detect, $16 Respond, $21 Automate) instead of per-GB, so your bill doesn't explode when you turn on logg
5. Microsoft 365 mentioned
   There's also a free tier that covers Microsoft 365 - genuinely useful as a starting point.
6. Huntress mentioned
   Huntress Managed SIEM - the pick if you already run (or would run) Huntress EDR.
7. Microsoft Sentinel mentioned
   Microsoft Sentinel - only if you're already deep in Microsoft 365 and Azure.
8. Azure mentioned
   Microsoft Sentinel - only if you're already deep in Microsoft 365 and Azure.
9. Wazuh mentioned
   Wazuh - the right answer if your budget is zero and you have Linux skills in-house or an MSP.
10. Linux mentioned
    Wazuh - the right answer if your budget is zero and you have Linux skills in-house or an MSP.
11. Arctic Wolf mentioned
    Arctic Wolf - service-led SOC with a named concierge team.
12. Graylog Security mentioned
    Graylog Security - consider if your actual problem is log search and compliance evidence more than threat detection.

The answer, as recorded

Searched - quick caveat on what's out there: a lot of the top-ranking "best SIEM for small business 2026" listicles are affiliate/aggregator pages, and some of their picks are absurd for a genuinely small company (one ranks Sumo Logic #1 at $270/GB/month and IBM QRadar #2 at "$5,000-$250,000/year"). Here's what I'd actually name. ## The short answer **1. Blumira** - my default recommendation for a small business. It's the one SIEM built for companies without a security team: cloud-native, pre-tuned detections so you're not writing correlation rules, 24/7 support, and per-employee pricing (~$12/employee/mo Detect, $16 Respond, $21 Automate) instead of per-GB, so your bill doesn't explode when you turn on logging. There's also a free tier that covers Microsoft 365 - genuinely useful as a starting point. **2. Huntress Managed SIEM** - the pick if you already run (or would run) Huntress EDR. Log collection plus a real 24/7 SOC that investigates and tells you what to do, rather than handing you alerts. Costs more than Blumira and is more feature-heavy; worth it when you want humans on the other end. **3. Microsoft Sentinel** - only if you're already deep in Microsoft 365 and Azure. Then it's arguably free-ish to start: M365 E5 includes a 5 MB/user/day ingestion grant, and Azure Activity, Office 365 audit logs, and Defender alerts ingest at no charge. But it's per-GB ($4.30 pay-as-you-go, ~$2.96 at the 100 GB/day tier), it's a build-it-yourself product, and 3-8 GB/day lands around $390-$1,030/month. Route forensic logs to the cheaper Data Lake tier ($0.05/GB ingest). **4. Wazuh** - the right answer if your budget is zero and you have Linux skills in-house or an MSP. Fully open source under Apache 2.0, no feature paywall, no license tier games. The cost is your time: it needs real administration and tuning, and nobody is watching it at 2 a.m. but you. **5. Arctic Wolf** - service-led SOC with a named concierge team. Legitimately good, but priced and scoped for mid-market; most small businesses will find it heavier and pricier than they need. **6. Graylog Security** - consider if your actual problem is log search and compliance evidence more than threat detection. Note the commercial security tier starts around $15,000/year, which puts it past most small-business budgets; the open-source edition is the more realistic entry point. ## What I'd skip Splunk, IBM QRadar, Sumo Logic, and Exabeam/LogRhythm. All capable platforms, all assuming a security analyst exists to operate them. For a small business they're a way to spend five figures and still miss the incident. ## The honest framing If "small business" means under ~100 employees with no dedicated security staff, a raw SIEM is usually the wrong purchase - it produces alerts nobody triages. Buy managed detection with SIEM inside it (Blumira or Huntress) and spend the leftover money on MFA everywhere, backups you've tested restoring, and EDR on every endpoint. Those stop more real attacks per dollar than any log platform.
