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 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. **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). **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 doing both jobs. There's a free tier for a small number of endpoints. **4. OpenVAS / Greenbone Community Edition** - The answer when the budget is zero. Fully open source and capable, but you host and maintain it yourself, and the UI and reporting are rougher than the commercial options. Good fit if you have Linux skills in-house and a small footprint. **5. Acunetix (Invicti)** - Pick this instead of the above if your main risk is a *web application* you built or run, rather than a fleet of machines. It's fast, accurate on web-specific flaws, and commonly used by smaller orgs starting application security work. **6. Rapid7 InsightVM** - Worth a look once you've outgrown the simple tools and need real remediation workflow, ticketing integration, and risk prioritization across a growing estate. **Qualys VMDR** I'd mention but not lead with for a small business - roughly $199 per asset per year with patch management included. It's excellent and compliance-heavy, but the per-asset model and enterprise complexity usually make it a worse fit than Intruder at this size. Practical note: these are complements, not substitutes. A very common small-business setup is Intruder (or Nessus) for scanning plus whatever your endpoint/patch tool already is - don't buy two overlapping platforms.
