6. Azure mentioned
   The reason is a pricing quirk that matters enormously at small scale: M365 audit logs, Azure Activity logs, and Defender XDR alerts ingest free, which in a Microsoft-heavy shop is often 30-50% of your total log volume.

The answer, as recorded

## Short answer For most small businesses, the right pick is **Blumira** (if you want it easy) or **Wazuh** (if you have technical staff and no budget). Everything else is situational. --- **1. Blumira** - My default recommendation for a small business with a lean or non-existent security team. It's priced per employee rather than per GB ingested ($12/user/mo Detect, $16 Respond, $21 Automate, billed annually), which means your bill doesn't explode the month someone turns on verbose logging - unlimited data ingestion is included on every tier. Detections come pre-tuned with plain-English remediation steps, and support is included rather than a paid add-on. The main caveat: the old free M365 tier has been retired, so you're looking at a 30-day trial instead. ([Blumira pricing](https://siemcostcalculator.com/blumira-pricing), [Capterra reviews](https://www.capterra.com/p/208225/Blumira/reviews/)) **2. Wazuh** - The best option if you have someone genuinely technical and your budget is near zero. Free and open source, self-hostable, and it's an XDR as much as a SIEM (file integrity monitoring, vulnerability detection, agent-based endpoint telemetry). The catch is real though: you own the tuning, the storage, and the 2am alerts. Their managed cloud starts around $571/mo for up to 100 agents if you want the software without the babysitting. ([Wazuh vs Blumira comparison](https://www.peerspot.com/products/comparisons/blumira-40249_vs_wazuh)) **3. Microsoft Sentinel** - Only if you're already on Microsoft 365 E5 or have the E5 Security add-on. The reason is a pricing quirk that matters enormously at small scale: M365 audit logs, Azure Activity logs, and Defender XDR alerts ingest **free**, which in a Microsoft-heavy shop is often 30-50% of your total log volume. Everything beyond that is $4.30/GB pay-as-you-go. If you're not a Microsoft shop, skip it - per-GB pricing is how small businesses get surprise four-figure bills. Note Sentinel is being folded into the Defender portal, with all workspaces migrated by March 31, 2027. ([Microsoft Sentinel pricing](https://www.microsoft.com/en-us/security/pricing/microsoft-sentinel), [pricing breakdown](https://siemcostcalculator.com/sentinel-pricing)) **4. Huntress Managed SIEM** - Worth a quote if what you actually want is people, not software. Huntress is built around a human-led SOC that triages for you, which is the honest answer for a lot of small businesses that would otherwise buy a SIEM and never look at it. Pricing is quote-only, which is a mark against it. ([Huntress alternatives roundup](https://underdefense.com/blog/huntress-alternatives-9-security-providers-for-smbs-in-2026/)) **5. ManageEngine EventLog Analyzer** - The budget on-prem pick. Cheap, perpetual-license option available, solid log consolidation and compliance reporting (PCI, HIPAA). The UI feels dated and the detection content is weaker than Blumira's, but if your driver is "an auditor asked for log retention," it does that job for very little money. ([ManageEngine overview](https://www.softwareworld.co/siem-software-for-small-businesses/)) --- **Two I'd steer you away from despite seeing them recommended:** Sumo Logic and Elastic Security both show up at the top of SEO listicles for this query, and Sumo Logic in particular gets called "best for small business" - but its paid tiers run into the hundreds of dollars per GB/month, and Elastic is custom-quote with real engineering overhead. Both are genuinely good products aimed at bigger teams than yours. Splunk is the same story, more so. **The general rule:** at small-business scale, avoid per-GB pricing unless you're getting Microsoft's free-ingest carve-out. Per-employee or flat pricing protects you from the failure mode where the SIEM works fine and the invoice is what kills the project.
