The answer, as recorded

Searched - here's what I'd actually recommend, in order. ## My ranked picks **1. Blumira** - My default recommendation for a genuine small business with 1-3 people doing IT (often as part of a broader job). It's built for teams without a SOC: guided deployment, pre-written detections you don't have to tune, and alerts that come with plain-English "do this next" playbooks rather than raw correlation output. There's a free-forever tier (3 cloud integrations, 14-day retention) so you can validate it on your M365 tenant before spending anything, and paid tiers start around $12/employee/month with month-to-month terms available. Main tradeoff: limited customization - if you want to write your own detection logic, you'll hit walls. ([blumira.com](https://www.blumira.com/comparing-value-blumira-delivered-superior-siem-capabilities)) **2. Microsoft Sentinel** - The right answer if you're already on Microsoft 365 Business Premium or E5 and Entra ID. Ingestion runs roughly $2.50-$5/GB, but the M365 and Entra audit-log connectors are free, which covers most of what a small shop actually needs to monitor. You get real SIEM power and KQL hunting. The catch is it's a toolkit, not a product - nobody is watching it for you, and costs can surprise you if you pipe in firewall or endpoint logs carelessly. Set ingestion caps on day one. ([costbench.com](https://costbench.com/best/siem-for-small-business/)) **3. Huntress Managed SIEM** - Pick this if what you really want is *someone else* doing the watching. Huntress pairs log collection with a human-led 24/7 SOC that investigates and sends you remediation steps. It's the strongest option when you have no security staff at all, and it's a natural add-on if you already run Huntress EDR. Launched Sept 2024, so it's newer and thinner on log-source coverage than Sentinel. ([unio.digital](https://unio.digital/compare/huntress-vs-blumira)) **4. Wazuh** - The pick if you have real Linux skills in-house and a tight budget. GPLv2 core, free, self-hosted on OpenSearch; you get log analysis, file integrity monitoring, vulnerability detection, and endpoint agents on one VM. Your only cost is compute and your own time - and that time is the real price. Budget days, not hours, for setup and ongoing rule tuning. Don't choose this if nobody on the team enjoys maintaining infrastructure. ([tech-insider.org](https://tech-insider.org/wazuh-siem-setup-12-steps-2026/)) **5. Arctic Wolf** - Co-managed SIEM with a named concierge security team. Genuinely good, and often the answer when a cyber-insurance questionnaire or a customer security review is forcing your hand. But it's priced for mid-market - one documented SMB comparison had it ~$20k/year above Blumira - and contracts are typically annual. ([blumira.com](https://www.blumira.com/blog/small-automotive-company/)) **6. Elastic Security or Graylog Security** - Reasonable middle ground for a technical team that wants more control than Blumira and less babysitting than Wazuh. Note Graylog is open-core: the free tier is really a log manager, and the SIEM-grade detection features sit behind a commercial license. ([aimultiple.com](https://aimultiple.com/open-source-log-analysis-tools)) ## What I'd skip **Sumo Logic, Splunk, and CrowdStrike Falcon Next-Gen SIEM.** Some roundups rank Sumo Logic first for small business, but at ~$270/GB/month that list price is nonsense for an SMB budget - I'd treat that ranking as unreliable. These are all fine platforms aimed at organizations with dedicated security staff. ([costbench.com](https://costbench.com/best/siem-for-small-business/)) ## One honest caveat A SIEM is often not the first thing a small business should buy. If you don't yet have MFA everywhere, managed EDR, and offline backups, those three deliver far more risk reduction per dollar than log aggregation - a SIEM only tells you something happened. If you're buying because of a compliance or insurance requirement, go Blumira or Huntress and move on. If you're buying because you want visibility and already have the fundamentals, Sentinel is the better long-term investment. Pricing above is list/approximate and moves around; confirm with vendors directly. A couple of the roundup sites I hit (costbench, tech-insider) look like low-quality SEO content, so I'd weight the vendor pages and your own trial over their rankings. **Sources:** - https://www.blumira.com/comparing-value-blumira-delivered-superior-siem-capabilities - https://www.blumira.com/blog/small-automotive-company/ - https://costbench.com/best/siem-for-small-business/ - https://unio.digital/compare/huntress-vs-blumira - https://tech-insider.org/wazuh-siem-setup-12-steps-2026/ - https://aimultiple.com/open-source-log-analysis-tools - https://www.crowdstrike.com/en-us/cybersecurity-101/next-gen-siem/next-gen-siem-for-small-business/
