Intruder** - My default pick for most small businesses. It's cloud-based (nothing to host), has genuinely transparent pricing - Essential at $99/mo, Cloud at $180/mo, Pro at $240/mo, with a 14-day trial - and it's built so a non-specialist can read the output and act on it. It continuously scans your external perimeter and alerts you when new CVEs affect things you expose. If you have a website, a few cloud servers, and no dedicated security person, start here.\n\n**2. Tenable Nessus Professional** - The industry workhorse and the deepest scanner on this list for internal/authenticated scanning of laptops, servers, and network gear. The catch is price: about $4,790/yr for Professional and $6,790/yr for Expert, which small-business reviewers routinely flag as steep. Worth it if you need thorough internal scans plus configuration and compliance audits (PCI, CIS benchmarks).\n\n**3. ManageEngine Vulnerability Manager Plus** - The one I'd name if you want *finding and fixing* in a single tool. It bundles scanning with actual patch deployment and hardening, which matters a lot when the same one or two people are do", "answer_truncated": true, "measurement": "One answer from one engine on one date.
