CAPTCHA & Bot Protection
3,100 of the 1,000,000 top sites in our Tranco top-1M census run AWS WAF CAPTCHA (0.3%). Amazon's CAPTCHA challenge product, part of AWS WAF's bot-mitigation features. Detection is homepage-level HTML/header fingerprinting, so a site can run AWS WAF CAPTCHA on other pages without it showing here.
