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

Brands named, in the order the engine gave

1. Huntress recommended
   Huntress Managed SIEM - my default recommendation for most SMBs.
2. Blumira mentioned
   Blumira - built specifically for small teams with no security staff.
3. Arctic Wolf compared
   Usually comes in materially cheaper than Arctic Wolf-class MDR for similar coverage.
4. Microsoft mentioned
   Microsoft Sentinel - the right call only if you're a Microsoft 365 E5/Business Premium-heavy shop.
5. Microsoft Sentinel mentioned
   Microsoft Sentinel - the right call only if you're a Microsoft 365 E5/Business Premium-heavy shop.
6. Sentinel mentioned

8. E5 mentioned
   Microsoft Sentinel - the right call only if you're a Microsoft 365 E5/Business Premium-heavy shop.
9. Defender mentioned
   Defender alerts ingest free, and E5/A5/F5/G5 gives you a 5 MB/user/day data grant, which covers a lot for a small org.
10. Wazuh mentioned
    Wazuh - the pick if you have real in-house Linux/sysadmin skill and a tight budget.
11. Linux mentioned
    Wazuh - the pick if you have real in-house Linux/sysadmin skill and a tight budget.
12. Elastic Security mentioned
    Elastic Security - good middle ground if you already run Elastic for logging or want to avoid per-GB ingest pricing.
13. Sumo Logic mentioned
    Sumo Logic - has a free tier and is genuinely easy to get started with, which is why it tops a lot of SMB lists.

The answer, as recorded

# SIEM for small businesses Honest framing first: most small businesses don't need a SIEM so much as they need *someone watching the alerts*. A raw SIEM with no one to triage it is an expensive log archive. So my list leans toward tools that come with detections (and often humans) built in. **1. Huntress Managed SIEM** - my default recommendation for most SMBs. It's priced per data source (~$4/month/source with a pooled 10 GB/month allocation per source, no overage surprises), and critically it comes with Huntress's SOC doing the triage. If you're already using their Managed EDR / M365 ITDR, this is the path of least resistance. ([pricing](https://www.huntress.com/pricing/siem)) **2. Blumira** - built specifically for small teams with no security staff. Fast to deploy, detections are pre-tuned, and it includes human support on alerts. Usually comes in materially cheaper than Arctic Wolf-class MDR for similar coverage. ([Blumira on SIEM for small business](https://www.blumira.com/blog/siem-for-small-business), [pricing overview](https://ethicalhacking.ai/pricing/blumira-siem-pricing)) **3. Microsoft Sentinel** - the right call *only if* you're a Microsoft 365 E5/Business Premium-heavy shop. Defender alerts ingest free, and E5/A5/F5/G5 gives you a 5 MB/user/day data grant, which covers a lot for a small org. The catch is it's consumption-priced per GB and costs are notoriously easy to blow up. Also: if you're pure M365 with no analysts, Defender XDR alone may genuinely be enough - don't buy Sentinel to not look at it. ([E5 data grant](https://azure.microsoft.com/offers/sentinel-microsoft-365-offer), [cost variability](https://microsoftnegotiations.com/blog/microsoft-sentinel-cost-optimization)) **4. Wazuh** - the pick if you have real in-house Linux/sysadmin skill and a tight budget. Open source and free to self-host, with FIM, vulnerability detection, and compliance mapping included. You pay in engineering hours instead of license fees, which is a fine trade for some shops and a disaster for others. ([Wazuh pricing](https://costbench.com/software/siem/wazuh/)) **5. Elastic Security** - good middle ground if you already run Elastic for logging or want to avoid per-GB ingest pricing. More assembly required than Blumira or Huntress. (~$95-175/month per resource per [this comparison](https://costbench.com/best/siem-for-small-business/)) **6. Sumo Logic** - has a free tier and is genuinely easy to get started with, which is why it tops a lot of SMB lists. I rank it lower because the paid cloud-SIEM tiers get expensive quickly at volume. ([same comparison](https://costbench.com/best/siem-for-small-business/)) **Worth naming but not a SIEM:** Arctic Wolf and similar MDR providers. If your actual problem is "nobody here can respond to an alert at 2am," an MDR contract solves that better than any SIEM you buy. Quoted costs for small orgs have run ~$20k/year higher than Blumira in at least one comparison, so get competing quotes. **Rough budget expectation:** under 100 staff at 5-50 GB/day of logs lands somewhere around $1,800-$36,000/year depending heavily on volume and whether humans are included ([pricing comparison](https://costbench.com/software/siem/)). If I had to pick blind with no other information: **Huntress** if you want it handled, **Blumira** if you want a dedicated SMB SIEM with support, **Wazuh** if you have the skills and not the budget.
