Brands named, in the order the engine gave

1. Blumira recommended
   Blumira - my default recommendation for most small businesses.
2. Microsoft mentioned
   The free tier covers unlimited users and data for Microsoft 365, no credit card, no sensor, no special Microsoft licensing - which means you can be running real detection on your M365 tenant this afternoon for $0.

   The free tier covers unlimited users and data for Microsoft 365, no credit card, no sensor, no special Microsoft licensing - which means you can be running real detection on your M365 tenant this afternoon for $0.
4. Microsoft Sentinel mentioned
   Microsoft Sentinel - if you're already on Microsoft 365 E5 / Defender.

6. Defender mentioned
   Microsoft Sentinel - if you're already on Microsoft 365 E5 / Defender.
7. Huntress mentioned
   Huntress - if what you really want is someone else doing the watching.
8. Arctic Wolf compared
   Worth noting: 80% of Huntress reviews come from small businesses, versus Arctic Wolf where ~70% are mid-market - Huntress is genuinely sized for you, not scaled down to you.
9. Wazuh mentioned
   Wazuh - if you have real technical capacity and no budget.
10. Graylog mentioned
    Graylog - if your pain is really log search, not threat detection.
11. Graylog Security mentioned
    Be aware the jump to Graylog Security is steep - around $1,550/month cloud, or ~$18,000/year - so treat the free tier as a destination, not a trial.
12. IBM mentioned
    Two I'd skip for a small business: Splunk and IBM QRadar - both excellent, both assuming a staffed SOC and an enterprise budget.

The answer, as recorded

For a small business, the honest framing is: a classic SIEM assumes you have someone to watch it. If you don't, pick something with detections pre-built or a SOC attached. Here's who I'd actually name, in order: **1. Blumira - my default recommendation for most small businesses.** It's built specifically for SMBs: detections arrive pre-tuned, so you get alerts with "here's what to do" playbooks rather than a firehose of raw logs. The free tier covers **unlimited users and data for Microsoft 365**, no credit card, no sensor, no special Microsoft licensing - which means you can be running real detection on your M365 tenant this afternoon for $0. Paid plans start around **$12/user/month** and add cloud, endpoint, and on-prem log sources. If you're an M365 shop with no dedicated security person, start here. ([blumira.com](https://www.blumira.com/why-blumira-launched-a-free-siem), [capterra.com](https://www.capterra.com/compare/208225-236404/Blumira-vs-Managed-Detection-and-Response-MDR)) **2. Microsoft Sentinel - if you're already on Microsoft 365 E5 / Defender.** It plugs straight into identity, Entra, and Defender signals with no connectors to build, and the free data grants for M365 audit logs make it cheaper than the sticker price suggests. Pricing is consumption-based at roughly **$2-$5/GB ingested**, which is the catch: it's fine until someone onboards firewall logs and the bill triples. Budget for log filtering from day one.

Huntress - if what you really want is someone else doing the watching.** Their Managed SIEM sits alongside their Managed EDR and comes with a human SOC that triages and escalates. Worth noting: **80% of Huntress reviews come from small businesses**, versus Arctic Wolf where ~70% are mid-market - Huntress is genuinely sized for you, not scaled down to you. This is the pick if "we have no security staff" is the real constraint.

Wazuh - if you have real technical capacity and no budget.** Free and open source with no volume cap, covering file integrity monitoring, vulnerability detection, and compliance reporting. It's the best functionality-per-dollar on this list by a wide margin. But you're running the infrastructure, tuning the rules, and watching the dashboard yourself - the license is free, your time isn't. Only pick this if someone on staff actually wants to own it. ([selecthub.com](https://www.selecthub.com/siem-tools/wazuh-vs-microsoft-sentinel/), [peerspot.com](https://origin.peerspot.com/products/comparisons/sentinel_vs_wazuh)) **5. Graylog - if your pain is really log search, not threat detection.** The open-source version is free up to **2 GB/day**, which is a comfortable fit for a small environment, and it's excellent for troubleshooting and investigation. Be aware the jump to Graylog Security is steep - around **$1,550/month cloud, or ~$18,000/year** - so treat the free tier as a destination, not a trial. ([costbench.com](https://costbench.com/software/log-management/graylog/), [itcentralstation.com](https://www.itcentralstation.com/products/graylog-pricing)) **6. Arctic Wolf - if you've grown past "small."** The Concierge Security model assigns you a named team that learns your environment, and customers rate the value highly. It's a strong product, but it's priced and scoped for mid-market, and pricing isn't public, so expect a sales cycle. ([g2.com](https://www.g2.com/compare/arctic-wolf-vs-huntress-managed-edr)) **Two I'd skip for a small business:** Splunk and IBM QRadar - both excellent, both assuming a staffed SOC and an enterprise budget. Also treat Sumo Logic's "best for small business" rankings with skepticism; at **$270/GB/month** it is not an SMB price point regardless of what the listicles say. ([costbench.com](https://costbench.com/best/siem-for-small-business/)) **What I'd do:** spin up Blumira's free M365 tier this week - zero cost, zero risk, and it tells you how noisy your environment actually is. That single data point will tell you whether you need a paid tier, a managed SOC like Huntress, or whether Wazuh would be enough.
