Intruder** - The default recommendation if you have a handful of internet-facing assets and no dedicated security person. It's SaaS, so nothing to host; it does continuous external attack-surface scanning and emails you when something new appears. Plans run roughly $99/mo (Essential), $180/mo (Cloud), $240/mo (Pro), with a free trial. Worth knowing what you're paying for: Essential runs OpenVAS under the hood, Cloud adds Nuclei, and Pro is where you get the Nessus engine - so the cheap tier is largely a managed wrapper around free tooling, which is fine if you value not running it yourself.\n\n**2. Tenable Nessus Professional** - The deepest, most credible scanner pedigree, and the one auditors and pentesters recognize. Unlimited assessments, CVSS v4, plus config/compliance audits (CIS benchmarks), which matters if you're chasing SOC 2 or cyber insurance requirements. List is $4,790/yr, dropping to ~$4,546/yr effective on a 3-year term. It's more hands-on - it scans, it doesn't manage the remediation workflow for you.\n\n**3. Microsoft Defender for Business** - Check this *before* buying anything. If you're on Micro", "answer_truncated": true, "measurement": "One answer from one engine on one date.
