Application for Membership

For CAs and Browsers Interested in Joining the CA / Browser Forum:

Browser manufacturers or developers of software that includes trusted root certificates may wish to consider joining the CA/Browser Forum.  Our Bylaws require that your organization “…produces a software product intended for use by the general public for browsing the Web securely.”

Our bylaws provide that CA members shall meet at least one of the following criteria:

  • Issuing CA:- The member organization operates a certification authority that has a current and successful WebTrust for CAs audit, or ETSI 102042 or ETSI 101456 audit report prepared by a properly-qualified auditor, and that actively issues certificates to Web servers that are openly accessible from the Internet using any one of the mainstream browsers.
  • Root CA:- The member organization operates a certification authority that has a current and successful WebTrust for CAs, or ETSI 102042 or ETSI 101456 audit report prepared by a properly-qualified auditor, and that actively issues certificates to subordinate CAs that, in turn, actively issue certificates to Web servers that are openly accessible from the Internet using any one of the mainstream browsers.
