Security & WAF
32,500 of the 965,200 top sites in our Tranco top-1M census run reCAPTCHA v2 (3.4%). Google's challenge-response service that verifies whether a site visitor is human or a bot. Detection is homepage-level HTML/header fingerprinting, so a site can run reCAPTCHA v2 on other pages without it showing here.
