## The answer, as recorded

Asked on 2026-10-26 through Claude (Anthropic) with web search (model claude-opus-5).

> # Vulnerability scanners for small businesses
> 
> Here's what I'd actually recommend, in rough order:
> 
> **1. Intruder** - My default recommendation for a small business that wants something that just works. It's built for exactly this market (~59% of its reviewers are small businesses), does continuous external attack-surface scanning, and emails you when something new appears rather than making you babysit a console. **$149/mo** (Essential, external-only), $299/mo Cloud, $499/mo Pro. Easiest setup of anything on this list.
> 
> **2. Tenable Nessus Essentials** - **Free for up to 16 IPs.** If your whole footprint is a handful of servers and a firewall, this is the best scan engine in the industry at zero cost. Nessus Professional (unlimited IPs, compliance templates, better reporting) jumps to roughly **$3,000-4,800/year** depending on term - a big step, and usually where small businesses should switch to Intruder or an MSP instead.
> 
> **3. Qualys Community Edition / Qualys VMDR** - Worth a look if you may grow into compliance work (PCI, SOC 2). Cloud-based with no appliance to run, strong asset inventory. Pricing is sales-quote only, which is itself a signal about who they're built for.
