The CA/Browser Forum has these working groups:
In 2005, Melih Abdulhayoglu of the Comodo Group organized2 the first meeting of CA/Browser Forum. The first meeting was held in New York City. This was followed by a meeting in November 2005 in Kanata, Ontario, and a meeting in December, 2005, in Scottsdale, Arizona with the main objective to enable secure connections between users and websites.
In addition to CA/Browser Forum members, representatives of the Information Security Committee of the American Bar Association Section of Science & Technology, Law and the Canadian Institute of Chartered Accountants participated in developing the standards for issuing and managing Extended Validation SSL/TLS certificates. Version 1.0 of the EV Guidelines was adopted on 7 June 2007.3
In November 2011, the CA/Browser Forum adopted version 1.0 of the "Baseline Requirements for the Issuance and Management of Publicly-Trusted Certificates" intended to provide minimum security standards for all browser-trusted SSL/TLS certificates. Subsequent versions expanded the Baseline Requirements to directly incorporate requirements from browser root store policy programs such as those of Mozilla and Microsoft.
In January 2013 the CA/Browser Forum's first "Network and Certificate System Security Requirements" took effect defining best practices for the general protection of CA networks and supporting systems.
In February 2013 a new industry group, the Certificate Authority Security Council (CASC), was formed with a mission that includes promoting CA/Browser Forum standards. Membership requires adherence to CA/Browser Forum standards.4 The CASC's founding members consisted Comodo CA (now Sectigo), Symantec (now DigiCert),5 Trend Micro (now Entrust), DigiCert, Entrust,6 GlobalSign7 and GoDaddy.89101112
In August 2020, the S/MIME Certificate Working Group13 was chartered to create a baseline requirement applicable to CAs that issue S/MIME certificates used to sign, verify, encrypt, and decrypt email.
In September 2020, the CA/Browser Forum adopted version 2.0 of the "Baseline Requirements for the Issuance and Management of Publicly-Trusted Code Signing Certificates", which had previously been maintained outside the group.
In January 2023, the CA/Browser Forum adopted version 1.0 of the "Baseline Requirements for the Issuance and Management of Publicly-Trusted S/MIME Certificates", It defined four types of S/MIME certificate standards. Mailbox-validated, Organization-validated, Sponsor-validated and Individual-validated.14
