## The answer, as recorded

> # Vulnerability scanners for small businesses
> 
> Here's what I'd actually recommend, roughly in the order I'd try them:
> 
> **1. Intruder** - My default recommendation for most small businesses. It's built for exactly your situation: continuous external scanning of your internet-facing stuff, automatic rescans when new CVEs drop, and reports you can hand to a client or auditor. Starts around **$149/month**, and it has the best ease-of-setup and support scores in its class (4.8/5 on G2, with the majority of reviews coming from small businesses). You don't need a security team to run it.
> 
> **2. Tenable Nessus Professional** - The industry standard for depth. If you have an internal network with servers, workstations, and network gear to audit, nothing beats it for coverage and CVSS-based detail. The catch is price and effort: **~$4,790/year** per scanner, plus $400 if you want 24/7 support. It's a tool, not a service - it finds things and hands you a list. Worth it if someone on your team will actually work the findings.
> 
> **3. Greenbone OpenVAS (Community Edition)** - The free option, and genuinely good. Over 160,000 vulnerability tests covering CVEs, misconfigurations, and default credent
