SSL/TLS Certificates
46,840 of the 1,000,000 top sites in our Tranco top-1M census run DigiCert (4.7%). 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.
