DigiCert - World's Largest High-Assurance Certificate Authority

DigiCert is the world's largest high-assurance certificate authority, commanding 52% of the Extended Validation SSL certificate market, and 88% of organisation-validated certificates (Netcraft SSL Survey, February 2019). Before its acquisition by DigiCert in October 2017, the Symantec PKI accounted for 43% of the Extended Validation SSL certificate market, and 29% of organisation-validated certificates. With brands including Thawte, and GeoTrust, Symantec had a long history in issuing SSL certificates. VeriSign's root certificate (acquired by Symantec in August 2010) was the first created and accepted by major browsers, and was seen in the first Netcraft SSL Survey in 1996. This page displays Symantec's history until December 2017, after which statistics account for all DigiCert certificates, including those issued by Symantec.

Netcraft's SSL Survey has been running since 1996 and has tracked the evolution of the SSL marketplace from its inception. The SSL Survey is trusted by the industry as a respected authority on market share, and has a wide range of clients, including certificate authorities, web hosting companies, banks, brokerages and government organisations.

DigiCert's SSL certificate count represents the number of SSL certificates found in the Netcraft SSL survey issued by DigiCert.
