SSL/TLS Certificates
339,096 of the 1,000,000 top sites in our Tranco top-1M census run Let's Encrypt (33.9%). 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.
