SSL/TLS Certificates
30,031 of the 965,200 top sites in our Tranco top-1M census run Sectigo (3.1%). A certificate authority that issues SSL/TLS certificates used to secure websites with HTTPS. Detection is homepage-level HTML/header fingerprinting, so a site can run Sectigo on other pages without it showing here.
