Intruder** - My default recommendation for most small businesses. It's SaaS, so there's nothing to host, it continuously scans your external-facing assets, and it tells you what matters without burying you in a 400-page report. Pricing is published rather than \"contact sales\": free tier, then ~$149/mo (Essential), $299/mo (Cloud), $499/mo (Pro). If you have one or two generalist IT people and no dedicated security staff, this is the least painful path.\n\n**2. Tenable Nessus** - The one to pick if you're more technical and want the deepest scan engine. **Nessus Essentials is free for up to 16 IPs**, which honestly covers a lot of small offices - start there before paying anyone. Nessus Professional is around $4,790/year for unlimited IPs per scanner. The tradeoff is that Nessus finds things but doesn't help you fix or track them; you own that workflow.\n\n**3. ManageEngine Vulnerability Manager Plus** - Best if you want scanning *and* patching in one tool.
