Security & WAF
804 of the 1,000,000 top sites in our Tranco top-1M census run PerimeterX (HUMAN) (0.1%). A bot detection and mitigation security platform that protects sites from automated traffic and fraud, now part of HUMAN Security. Detection is homepage-level HTML/header fingerprinting, so a site can run PerimeterX (HUMAN) on other pages without it showing here.
