The answer, as recorded

# Best SIEM for a small business Honest framing first: most small businesses don't actually want a SIEM - they want the *outcome* of one (someone watching logs 24/7 and telling them when something's wrong). So the top of my list leans toward managed/guided products, not raw log platforms you have to staff. **1. Blumira** - My default recommendation for a small business with a lean or part-time IT person. Cloud SIEM built specifically for SMBs, and critically it's priced **per employee (~$12/employee/month) with unlimited data ingestion**, so you don't get punished for turning on more log sources. It ships with pre-built detections and actual remediation playbooks instead of a blank query box. There's also a free tier for Microsoft 365 logs to try it. ([q-sec.com](https://q-sec.com/siem-knowledge-base/best-siem-for-small-business), [blumira.com](https://www.blumira.com/blog/siem-for-microsoft-365)) **2. Huntress Managed SIEM** - Pick this if you want a real 24/7 SOC doing the triage rather than doing it yourself. Huntress is the most SMB-native vendor in the space; its managed EDR runs around **$8.99/endpoint/month with SOC coverage included** (not an add-on), and its analysts investigate alerts and escalate under ~1% of them. Best value-per-dollar if you're also consolidating endpoint protection. ([huntress.com](https://www.huntress.com/comparison/huntress-vs-artic-wolf), [underdefense.com](https://underdefense.com/blog/huntress-alternatives-9-security-providers-for-smbs-in-2026/)) **3. Microsoft Sentinel** - Only if you're already all-in on Microsoft 365 E5/Defender and have someone comfortable with Azure and KQL. The integration is unbeatable there, but it bills **per GB ingested (~$2.46-$5.20/GB)**, which makes costs genuinely hard to predict, and it's frequently called out as not affordable for typical SMBs. Use commitment tiers and a data-collection filter from day one if you go this route. ([q-sec.com](https://q-sec.com/siem-knowledge-base/siem-pricing-comparison), [siemcostcalculator.com](https://siemcostcalculator.com/)) **4. Wazuh** - The answer if you have real Linux and security skills in-house and a tight budget. It's free and open source, and bundles log analysis, file integrity monitoring, vulnerability detection and endpoint agents in one platform. The catch is well documented: steep learning curve and ongoing maintenance, so the savings evaporate if you don't already have the expertise. Wazuh Cloud (from ~$571/month) removes the hosting burden but not the tuning burden. ([alekseialeinikov.com](https://www.alekseialeinikov.com/en/blog/topics/security/siem-pricing-wazuh-vs-sentinel-vs-google-secops-2026), [selecthub.com](https://www.selecthub.com/siem-tools/wazuh-vs-microsoft-sentinel/)) **5. Graylog Security (or Graylog Open)** - Good middle ground if you want a self-hosted platform that's noticeably friendlier than Wazuh or the Elastic stack to run and search. Solid for compliance-driven log retention where you mostly need searchable centralized logs plus some detection content. ([g2.com](https://www.g2.com/compare/falcon-next-gen-siem-vs-graylog)) **6. Arctic Wolf MDR** - Worth a quote only at the upper end of "small" (150+ users) and if you want a service-led SOC with a named concierge team. Realistically **$25-$40/user/month** once you add log retention beyond 90 days and the usual add-ons, so ~$5-8K/month at 200 users. More than most SMBs need to spend. ([huntress.com](https://www.huntress.com/comparison/huntress-vs-artic-wolf)) **Skip for now:** Splunk (~$1K/GB-class pricing), CrowdStrike Falcon Next-Gen SIEM, and Elastic Security unless you're already a CrowdStrike or Elastic shop - all three are strong products aimed at teams with dedicated security staff. ([siemcostcalculator.com](https://siemcostcalculator.com/), [crowdstrike.com](https://www.crowdstrike.com/en-us/platform/next-gen-siem/)) **If I had to give one answer:** start with Blumira if you'll run it yourself, Huntress if you want someone else to run it. One caveat on the pricing above - SIEM list prices move and vendors discount heavily on multi-year terms, so treat these as starting points for a quote, not quotes.
