Nessus Essentials (free) / Nessus Professional (~$3,600-4,400/yr)**\nThe default starting point. Essentials scans up to 16 IPs free, which covers a lot of genuinely small shops, and it's the same engine the paid product uses. Downside: it's a scanner, not a program - you get findings, not prioritization or workflow, and the learning curve is steeper than the SaaS options. Note the Pro license doesn't include web-app, cloud, or external attack-surface scanning.\n\n**2. Intruder (~$149/mo entry)**\nThe one I'd point a small business with no dedicated security person toward. Transparent pricing, near-zero setup, continuous external scanning with emerging-threat rescans, and it filters noise instead of dumping a 400-page CSV on you. About 60% of its reviews come from small businesses, which tells you who it's built for.\n\n**3. Qualys Community Edition (free, limited) or paid VMDR**\nWorth it if you want the deepest coverage and best compliance reporting, and the free tier handles 16 assets. But pricing is quote-only and the console is genuinely enterprise-shaped - it rewards someone who'll invest time in it.\n\n**4.
