SSL/TLS Certificates
33,361 of the 1,000,000 top sites in our Tranco top-1M census run Sectigo (3.3%). 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.
