SSL/TLS Certificates
43,731 of the 965,200 top sites in our Tranco top-1M census run DigiCert (4.5%). 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 DigiCert on other pages without it showing here.
