## The answer, as recorded

Asked on 2026-09-13 through Claude (Anthropic) with web search (model claude-opus-5).

> Here's what I'd actually recommend, roughly in the order I'd try them:
> 
> **1. Intruder** - My default suggestion for a small business with no dedicated security person. It's cloud-hosted (nothing to install), focused on your internet-facing attack surface, and it tells you what to fix first instead of dumping a 400-page CVE list on you. Under the hood it runs OpenVAS on the Essential plan and adds Nuclei on the Cloud plan, so you're getting solid engines with a usable interface bolted on. Starts in the low hundreds per month.
> 
> **2. CISA Cyber Hygiene Services** - Free, and I'd sign up for this *regardless* of what else you buy. US government service that continuously scans your public static IPs and web apps, emails you weekly reports plus urgent alerts. Takes ~72 hours to start after you email them. No reason not to have it running in the background. Caveat: it only covers internet-facing assets you own IPs for, so it's a complement, not a replacement.
> 
> **3. Greenbone / OpenVAS** - The answer if your budget is genuinely zero and you have someone comfortable running a Linux VM. Free, self-hosted, huge feed of network and host tests. The community edition is real work to maintain, so
