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)) > > **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.

Bikoosh is monitoring assistance, not complete protection. Answer Watch records what one AI answer engine said on one date, nothing more. Each page names the engine and the model, carries the date the question was asked, and lists the brands that appeared in the answer in the order the engine gave them, with the sources it cited. It is a measurement, not a ranking, not a recommendation and not a claim about the world. Brands that did not appear in an answer are not named on any public page.
