The CASC’s mission is to advance internet security by promoting deployments and enhancements to publicly trusted certificates and through public education, collaboration, and advocacy. The CASC strives for the adoption of digital certificate best practices and the proper issuance and use of digital certificates by CAs, browsers, and other interested parties.

Another part of the CASC’s mission is to be the voice of commercial CAs on matters that affect certificate issuance, website owner needs, and user security. CASC also supports efforts to promote the use and display of website owner identity information in OV and EV certificates for greater user security.
