Security & WAF
4,094 of the 1,000,000 top sites in our Tranco top-1M census run reCAPTCHA Enterprise (0.4%). Google's paid, enterprise-tier bot-detection and risk-scoring service for protecting sites from automated abuse. Detection is homepage-level HTML/header fingerprinting, so a site can run reCAPTCHA Enterprise on other pages without it showing here.
