Security & WAF
679 of the 1,000,000 top sites in our Tranco top-1M census run CHEQ (0.1%). A cybersecurity platform that detects bots and invalid traffic to protect ad spend, forms, and analytics. Detection is homepage-level HTML/header fingerprinting, so a site can run CHEQ on other pages without it showing here.
