SSL/TLS Certificates
325,744 of the 965,200 top sites in our Tranco top-1M census run Let's Encrypt (33.7%). A free, automated certificate authority that issues and renews SSL/TLS certificates for HTTPS. Detection is homepage-level HTML/header fingerprinting, so a site can run Let's Encrypt on other pages without it showing here.
