Even though the company uses a cloud service provider (CSP) that is PCI compliant, the customer must still ensure that in-scope systems related to their new payment system offering are also PCI compliant. PCI DSS (Payment Card Industry Data Security Standard) applies to any system that processes, stores, or transmits credit card data, and this includes customer-owned systems, services, or applications integrated into the solution. The responsibility is shared between the CSP and the customer, and compliance is not automatically inherited just because the CSP is compliant. CASP+ emphasizes that organizations must ensure all components within their control are also PCI compliant.
