The answer, as recorded

Here's what I'd recommend, in order. Which one fits you depends mostly on whether anyone on your team can run a security tool day to day. **1. Blumira: my first pick if you have no dedicated security person.** It's built for small and mid-sized businesses. It sends you prioritized alerts with step-by-step response playbooks instead of raw logs. Pricing is per employee: $12 per month for the Detect edition, $16 for Respond and $21 for Automate, with unlimited data ingestion. That makes costs easier to predict than per-GB billing. Sources disagree on whether its free Microsoft 365 tier still exists. One 2026 source says it was retired and replaced by a 30-day trial, so check before you plan around it. - https://siemcostcalculator.com/blumira-pricing - https://www.scworld.com/news/blumira-offers-smbs-free-cloud-based-siem-for-microsoft-365 **2. Microsoft Sentinel: best if you already run on Microsoft 365 or Azure.** It's a cloud SIEM with strong Microsoft integrations and automation. Several log sources are free to ingest for everyone, including Office 365 audit logs, Azure Activity logs and alerts from Microsoft Defender products. Microsoft 365 E5 customers also get up to 5 MB per user per day of extra ingestion. Other data is billed per GB, around $2.46 to $5.20. That can add up: one estimate puts 10 GB a day at about $1,290 a month. You'll also need some Azure skills to set it up well. - https://learn.microsoft.com/en-us/azure/sentinel/billing - https://siemcostcalculator.com/sentinel-pricing - https://www.peerspot.com/products/comparisons/microsoft-sentinel_vs_wazuh **3. Wazuh: best if you have technical staff and a tight budget.** It's free and open source, with no features locked behind a paid edition. It covers log analysis, file integrity monitoring (alerts when important files change), vulnerability scanning, intrusion detection and compliance reporting. The trade-off is that you pay in servers and staff time to deploy, tune and maintain it. Wazuh also sells a paid cloud version if you don't want to host it yourself. - https://wazuh.com/ - https://blog.canadianwebhosting.com/wazuh-open-source-siem/ **4. ManageEngine Log360 or EventLog Analyzer: good for Windows and Active Directory setups on your own servers.** They're affordable and cover log management, threat detection and compliance reporting. They suit an IT generalist more than a security analyst. - https://sourceforge.net/software/siem/for-small-business/ - https://itwisetech.com/blogs/best-siem-tools-small-businesses-2026/ **5. Sumo Logic or Elastic Security: strong cloud options if you're growing and log-heavy.** Some comparison sites rank Sumo Logic first for small businesses and note it has a free tier. But the paid price one site lists ($270/GB/month) looks wrong, so get a real quote. Elastic is powerful but takes more skill to run. - https://costbench.com/best/siem-for-small-business/ - https://www.capterra.com/siem-software/s/small-businesses/ **One honest caveat:** a SIEM only helps if someone watches and acts on its alerts. If nobody on your team can do that, a managed detection and response (MDR) service or a managed SIEM from an IT provider is often a better use of the money. Huntress and Arctic Wolf are common options for small businesses, though I didn't look them up here.
