DigiCert Inc is a privately held, US based X.509 SSL certificate provider. As a trusted third party, DigiCert verifies the authenticity of secure websites on behalf of a web browser for the purpose of preventing online phishing scams.

As a founding member of the CA/Browser Forum, the industry standards group founded by Melih Abdulhayoğlu of the Comodo Group,[1] DigiCert assisted in the development of the Extended Validation Certificate, which provides enhanced identity verification of certificate holders.[2] DigiCert also worked in conjunction with Microsoft to develop and promote the use of subject alternate names in SSL certificates, for use with Microsoft Exchange Server.[3]

DigiCert is the largest public CA that does not issue "domain validated", "low assurance", or "instant" SSL certificates either directly or through a subsidiary brand. It primarily sells Organization Validation (OV) and Enhanced Validation (EV) SSL certificates..[4]

DigiCert Inc. is of no relation to Digicert Sdn. Bhd, a Malaysian-based certification authority that issues certificates with weak keys and had its trust revoked by web browsers.[5][6][7]


DigiCert was founded by Ken Bretschneider in 2003. He was named as a finalist in the Ernst & Young Entrepreneur of the Year Award in 2012 as a result.[8][9] He served as CEO and Chairman of the Board until he left in 2012 to head up People Water.[10] Nicholas Hales now serves as CEO of Digicert [11] which is currently majority owned by private equity firm TA Associates [12]
