SSL/TLS Certificates
45,158 of the 965,200 top sites in our Tranco top-1M census run Amazon (ACM) (4.7%). AWS Certificate Manager, a service for provisioning and managing SSL/TLS certificates on AWS resources. Detection is homepage-level HTML/header fingerprinting, so a site can run Amazon (ACM) on other pages without it showing here.
