Certificate Authority Market Share Report
January 1st, 2022

Report Description
This report, much like our original certs and CAs report, focuses on issuers of SSL enabling certificates found on web servers. Unlike our original report, however, this report has a couple of key differences to it:

  • Reports on top 100 CAs. The original report only paid attention to the major CAs at the time the report was produced. This report lists the top 100 CAs for the month. You will find here many self-signing organizations such as universities, telecommunications firms, etc.
  • Uses issuer name as identifier. Our original report only counted a certificate towards an organization if we were able to prove, by virtue of verifying the key, that the organization in question actually signed the certificate. This had a notable problem with it - we don't always have the public key of the CA. In at least one case, a CA doesn't make their public key available unless you sign a license agreement.

    This report doesn't have that problem, since it only uses the issuer Organization Name to uniquely identify the issuing CA.

Note: Readers are cautioned that the Growth percentages are based on a CA's market share penetration rather than the absolute number of certificates we detected. Thus, it is possible for the number of certificates to increase, while the growth is actually a negative value.
