SSL/TLS Certificates
267,834 of the 965,200 top sites in our Tranco top-1M census run Google Trust Services (27.7%). 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.
