## The answer, as recorded

> Here's what I'd actually recommend, roughly in the order I'd try them:
> 
> **1. Intruder** - My default pick for a typical small business. It's a SaaS external/internal scanner built for teams without a security person: you point it at your public IPs and domains, it scans continuously, and it filters out the noise so you get a short list of things that actually matter. Plans start around $119/mo (Essential), $239 (Cloud), $399 (Pro), plus a per-target fee - the pricing page uses a slider, so get a quote for your target count. 14-day free trial.

> 
> **2. Microsoft Defender Vulnerability Management** - If you're already on Microsoft 365, this is the cheapest path to real coverage: $3/user/month standalone, $2/user/month as an add-on if you have Defender for Endpoint P2, and free if you're on M365 E5. It scans the laptops and servers you already manage and ties findings to patching. Nothing beats it on price-per-value when you're in the Microsoft ecosystem.

Answer Watch records what one AI answer engine said on one date, nothing more. Each page names the engine and the model, carries the date the question was asked, and lists the brands that appeared in the answer in the order the engine gave them, with the sources it cited. It is a measurement, not a ranking, not a recommendation and not a claim about the world. Brands that did not appear in an answer are not named on any public page.
