## The answer, as recorded

Asked on 2026-09-27 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 pick for most small businesses. It's SaaS (nothing to host), scans your external perimeter continuously, and alerts you when a new CVE affects something you expose. The reporting is clean enough to hand to a client or auditor, which matters if you're chasing SOC 2 or Cyber Essentials. Pricing is per-target and quoted inconsistently across review sites - anywhere from ~$119/mo to ~$352/mo for 100 targets depending on plan and source - so get a real quote rather than trusting an aggregator.

> 
> **2. ManageEngine Vulnerability Manager Plus** - Best value if your problem is *internal* machines (unpatched laptops, servers, misconfigs) rather than public-facing assets. Its differentiator is that it scans *and* patches in one workflow, so you're not exporting a CSV and chasing fixes by hand. There's a free tier for a small number of endpoints - verify the current device cap on their site, as it's changed over the years. ([esecurityplanet.com](https://w
