This analysis relates to those sites found in the survey where the certificate authority certified the organisation (so more than ownership of the domain was checked) (plus the certificate is valid and the common name certificate matched the hostname).
The following graph shows the share of sites currently certified by each certificate authority. Brands belonging to the major companies have been grouped together.
The worldwide version of this data is available on a separate page.
The following table and graph show the change over time of the number of sites certified by the main CA companies. The different brands of the major players are grouped together (so RSA Data Security & Thawte are included in Verisign; Equifax and UserTrust are included in GeoTrust).
