> # Best SIEM for small businesses
> 
> Short version: for most small businesses, the right answer is a **managed/co-managed SIEM** with predictable pricing, not a traditional per-GB enterprise platform. Here's who I'd actually name, in order:
> 
> **1. Blumira** - My default recommendation for a small business with no dedicated security team. It's priced per employee (~$12-$21/user/month), so your bill doesn't explode when log volume spikes - the single biggest budget trap with SIEM. Detections come pre-tuned with plain-English response playbooks, and setup is days, not months. Downside: less flexible than a true platform if you have unusual data sources.
> 
> **2. Microsoft Sentinel** - The obvious pick if you're already on Microsoft 365 Business Premium or E5. Connectors for Entra ID, Defender, and Office are free or cheap to ingest, and you may already own much of the licensing. It's ~$2.46-$5.20/GB ingested, which is fine at small volume but genuinely hard to forecast - set ingestion caps and commitment tiers on day one. Also the most likely to need a consultant or MSP to configure properly.
> 
> **3. Huntress Managed SIEM** - Strong fit if you want one vendor covering EDR, identity, and logs w
