PCI DSS QSA companies: how to check the PCI SSC list and shortlist an assessor
The PCI Security Standards Council publishes the official QSA list. This page quotes how that list works, how to check a name on it, and how the 164 PCI DSS firms in this directory break down by headquarters country. Not a ranking.
The official list
“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.” [1]
QSAs are “re-qualified as QSAs each year”. “The PCI Security Standards Council does not endorse these security solution providers”. [1]
The Council “cannot guarantee that the list is up-to-date at all times”, so “each time a client engages a QSA, they are advised to check this list”. [1]
“'In Remediation' status indicates a determination by the Council, after Quality Assurance review, that a QSA organization has violated applicable QSA Validation Requirements.” [1]
