SSL/TLS Certificates
280,976 of the 1,000,000 top sites in our Tranco top-1M census run Google Trust Services (28.1%). Google's certificate authority, issuing SSL/TLS certificates used to secure sites with HTTPS. Detection is homepage-level HTML/header fingerprinting, so a site can run Google Trust Services on other pages without it showing here.
