Assessors
All potential assessors wishing to perform PCI Data Security Assessments for merchants and service providers must be approved by the PCI SSC as a Qualified Security Assessor ("QSA"). In addition, the ownership and management of Visa's Qualified Payment Application Security Companies ("QPASC") program has transitioned to the PCI SSC as a Payment Application Qualified Security Assessor ("PA-QSA"), effective April 2008. Please visit the PCI Security Standards Council for details on the QSA and the PA-QSA Programs, requirements, updated training schedules and related information.
