Qualified Security Assessor (QSA) companies are independent security organizations that have been qualified by the PCI Security Standards Council to validate an entity’s adherence to PCI DSS. QSA Employees are individuals who are employed by a QSA Company and have satisfied and continue to satisfy all QSA Requirements.

Please note, the PCI Security Standards Council maintains an in-depth program for security companies seeking to be certified as Qualified Security Assessors, and to be re-certified as QSAs each year.

Certification and re-certification indicate only that the applicable QSA has successfully met all PCI Security Standards Council requirements to perform PCI DSS Assessments, and the PCI Security Standards Council does not endorse these security solution providers or their business processes or practices.

Although the PCI Security Standards Council strives to ensure that the list of Qualified Security Assessors linked to on this page is current, it is updated frequently and the Council cannot guarantee that the list is up-to-date at all times. Accordingly, each time a client engages a QSA, they are advised to check this list to ensure that its advisor has successfully maintained its status as a Qualified Security Assessor.
