Intruder - the default pick for most small businesses.** Cloud-based external scanning with almost no setup: point it at your domains/IPs and cloud accounts, and it continuously re-scans when new vulnerabilities drop. It's built for teams without a security person, and it prioritizes aggressively so you don't drown in findings. Entry plans run ~$99-$149/month, which is the most realistic price point on this list.\n\n**2. Nessus Essentials (free) → Nessus Professional.** The industry-standard scanner with the biggest plugin library (200,000+). Essentials is free but capped at **16 IPs** - genuinely enough for a small office or a handful of servers, and the best zero-cost way to learn what's actually broken on your network. The jump to Professional is steep (~$3,990-$4,390/year), so treat that as the moment you've outgrown free tooling.\n\n**3. Greenbone OpenVAS Community Edition - best free option with no host cap.** ~160,000 tests, $0, unlimited hosts. The tradeoff is you run and maintain it yourself (Docker/VM), and the UI and reporting are rougher. Good if you have someone technical and more than 16 IPs to c", "answer_truncated": true, "measurement": "One answer from one engine on one date.
