The question asked, verbatim: best siem software for small businesses. This page records one answer on one date. It is a measurement, not a ranking and not a recommendation.

Brands named, in the order the engine gave

1. Blumira recommended
   Blumira - This is my default recommendation for most small businesses.
2. Google Workspace recommended
   There's also a free tier for M365/Google Workspace logging that's a legitimate starting point.
3. Microsoft Sentinel recommended
   Microsoft Sentinel - Best choice if you're already a Microsoft 365 E5 / Defender shop.
4. Huntress recommended
   Huntress (Managed SIEM + EDR) - Pick this if what you actually want is "someone else watches this for me." Huntress runs a real 24/7 SOC and their EDR is well regarded in the SMB/MSP market.
5. Wazuh recommended
   Wazuh - The right answer only if you have real in-house Linux/ops skill and more time than money.
6. Linux recommended
   Wazuh - The right answer only if you have real in-house Linux/ops skill and more time than money.
7. Arctic Wolf recommended
   Arctic Wolf - Full MDR rather than SIEM-you-operate;
8. Splunk mentioned
   Splunk, IBM QRadar, Sumo Logic, Elastic Security.
9. IBM mentioned
   Splunk, IBM QRadar, Sumo Logic, Elastic Security.

The answer, as recorded

## Short answer For a genuinely small business, the honest recommendation order is: **1. Blumira** - This is my default recommendation for most small businesses. It's the one SIEM actually designed around the constraint that you don't have a security analyst on staff. Per-user pricing (~$12-21/user/month depending on tier) instead of per-GB means your bill doesn't explode when you turn on more logging, which is the single most common way small companies get burned by SIEM. Detections ship pre-tuned, and alerts come with written response steps rather than a raw event you have to interpret. There's also a free tier for M365/Google Workspace logging that's a legitimate starting point. ([Blumira pricing/positioning](https://www.blumira.com/arcticwolf), [MSP Compared](https://mspcompared.com/blumira/alternatives/)) **2. Microsoft Sentinel** - Best choice *if* you're already a Microsoft 365 E5 / Defender shop. Defender XDR alerts and raw data, Entra ID Protection alerts, Azure Activity, and O365 audit logs ingest **free**, plus a 5 MB/user/day grant with E5. That can make the effective cost near-zero for the logs you care about most. The catch: Sentinel is a build-it-yourself SIEM. Budget for a partner to set up rules and workbooks, or it becomes an expensive log bucket. Pay-as-you-go is ~$4.30/GB otherwise. ([Microsoft Learn billing](https://learn.microsoft.com/en-us/azure/sentinel/billing), [CyberOne](https://cyberone.security/blog/microsoft-sentinel-pricing-explained-analytics-data-lake-tiers-in-2026)) **3. Huntress (Managed SIEM + EDR)** - Pick this if what you actually want is "someone else watches this for me." Huntress runs a real 24/7 SOC and their EDR is well regarded in the SMB/MSP market. Their SIEM is newer than their endpoint product, so you're buying it mainly for the managed service and the endpoint coverage, not for SIEM depth. Custom quote, generally more expensive than Blumira. ([PeerSpot comparison](https://www.peerspot.com/products/comparisons/blumira-cloud-siem_vs_huntress-managed-siem)) **4. Wazuh** - The right answer only if you have real in-house Linux/ops skill and more time than money. Free and open source, self-hosted, genuinely capable (SIEM + XDR + FIM + compliance reporting). Managed cloud starts around $571/month for 100 agents. The "free" version costs you an engineer's ongoing attention - tuning, storage, upgrades. Great for a technical founder; a trap for a business without one. ([PeerSpot](https://www.peerspot.com/products/comparisons/huntress-managed-siem_vs_wazuh)) **5. Arctic Wolf** - Full MDR rather than SIEM-you-operate; you get a named Concierge Security Team. Users rate satisfaction highly. I put it last for *small* businesses purely on cost and contract structure - annual commitments, opaque pricing, and it's really aimed at mid-market. Consider it if you're 200+ seats or have a compliance/insurance mandate for 24/7 monitoring. ([G2 comparison](https://www.g2.com/compare/arctic-wolf-vs-blumira-automated-detection-response)) ## What I'd skip **Splunk, IBM QRadar, Sumo Logic, Elastic Security.** Some listicles rank Sumo Logic or QRadar as "best for small business" - ignore that. QRadar starts around $5,000/year and scales into six figures; Sumo Logic's paid tiers run ~$270/GB/month. These are enterprise tools with enterprise operating requirements. Elastic Security is powerful and cheap on license but is effectively a build-your-own project like Wazuh, without Wazuh's out-of-box security content. ([Costbench](https://costbench.com/best/siem-for-small-business/), [SentinelOne](https://www.sentinelone.com/cybersecurity-101/data-and-ai/siem-solutions/)) ## Two caveats worth stating plainly - Most "best SIEM 2026" listicles are affiliate-driven and their rankings don't reflect what small businesses actually deploy successfully. I weighted practitioner comparisons and vendor pricing pages over those. - If you have fewer than ~50 employees and no dedicated IT security person, **the honest answer may be that you don't need a SIEM yet**. Managed EDR (Huntress, SentinelOne, or Defender for Business at ~$3/user/month) plus MFA everywhere will buy you far more risk reduction per dollar. SIEM earns its keep once you have a compliance requirement, cyber-insurance demand, or enough systems that correlation across them matters.
