## The answer, as recorded

> # Vulnerability scanners for small businesses
> 
> The honest starting point: for most small businesses the winner isn't the most powerful scanner, it's the one that keeps running after month one without a dedicated security person. Ranked roughly in the order I'd actually suggest them:
> 
> **1. Intruder** - My default pick for a small business with an internet-facing footprint and no security staff. Continuous external scanning, plain-English results, and it proactively re-scans when big new CVEs drop. Pricing is public and starts around **$101-$149/month** for a small number of targets (Essential tier), Pro from ~$163/month. The main reason it's first: the reports are written for someone who isn't a pentester, so findings actually get fixed.
> 
> **2. Microsoft Defender Vulnerability Management** - If you're already a Microsoft 365 shop, this is the cheapest credible option at **$3/user/month standalone** (or $2 as an add-on to Defender for Endpoint P2, and free with M365 E5). Agentless scanning of your laptops and servers, software inventory, risk prioritisation, and it hands off patching to Intune. It covers your endpoints, not your public web apps - so it pairs with, rather than replaces
