PCI DSS och QSA: Nyckeln till säkra betalningsprocesser

QSA (Qualified Security Assessor) is a person or company that has been certified by the PCI Security Standards Council to assess organizations for compliance with PCI DSS. QSAs are responsible for conducting on-site assessments of a company’s systems and processes to determine whether they meet the requirements of PCI DSS.
The relationship between PCI DSS and QSA is that companies must meet the requirements of PCI DSS to accept credit card payments from their customers. QSAs are the certified individuals or companies that assess whether a company is meeting these requirements. By working with a QSA, companies can ensure that they are compliant with PCI DSS and can continue to accept credit card payments securely.
