Intruder** - Best default for most small businesses. Cloud-based, external + internal scanning, genuinely good at surfacing the handful of things that matter instead of a 400-page PDF. No appliance to maintain, and it's the one tool on this list whose customer base is actually majority small business (~57% of reviews). Entry pricing starts around **$149/month**, with the fuller plan around $199/month. ([G2 comparison](https://www.g2.com/compare/intruder-vs-tenable-nessus-vs-insightvm-nexpose), [Intruder](https://www.intruder.io/blog/the-top-vulnerability-scanning-tools))\n\n**2. CISA Cyber Hygiene Scanning** - Do this one regardless of what else you buy, because it's **free**. CISA continuously scans your internet-facing IPs and sends weekly reports with remediation guidance; setup is an email and some paperwork, scanning starts within ~72 hours. Many cyber-insurance carriers accept these reports in place of a paid annual third-party scan, which is a real money-saver. US organizations only.
