- pfg 11y ago4th largest counting certificates that are either on Certificate Transparency Log servers or in censys' data set. CT logs are populated by CAs sending their certificates to log servers. Only a few CAs (including Let's Encrypt) do this consistently at the moment, since it's only mandatory for EV certs (for now), and CAs generally move rather slowly. Certificates encountered by Googlebot during web crawling also get pushed to their log servers. Censys probably does something similar. It's possible that there's a large number of certificates issued only for internal systems that would not end up on CT log servers and that are not accessible by public crawlers, so the numbers are probably not painting a full picture. It is, however, as close as you can get to the full picture unless every CA is willing to release their internal numbers.
