Intruder - my default pick for most small businesses.** Continuous external/perimeter scanning with an \"autoscanner\" that re-scans when new CVEs drop, plus a genuinely plain-English UI. Entry pricing around $149/month, and it's the one scanner on this list that's majority small-business by customer base (~58% of its reviews), so the product is designed for teams without a security hire. Strongest ease-of-use and support scores of the big three. ([G2 comparison](https://www.g2.com/compare/intruder-vs-tenable-vulnerability-management))\n\n**2. Tenable Nessus - the gold standard if you have someone technical.** The biggest plugin library and the deepest authenticated scanning of internal assets. Two caveats: **Nessus Essentials is free but capped at 16 IPs**, which is fine for a very small office or a test, and Nessus Professional runs roughly $3,590-$4,790/year for one scanner. It's also a scanning engine, not a managed program - it tells you what's broken, it doesn't help you triage. ([Nessus vs OpenVAS 2026](https://ethicalhacking.ai/compare/nessus-vs-openvas))\n\n**3.
