Are merchants using P2PE solutions required to validate PCI DSS compliance?

Merchants using Point-to-Point Encryption (P2PE) solutions are indeed required to validate PCI DSS compliance. The reason for this is that while P2PE can significantly reduce the scope of the PCI DSS assessment, it does not completely exempt merchants from compliance obligations. P2PE is designed to protect cardholder data during transmission, thus enhancing security; however, merchants must still ensure that they maintain compliance with PCI DSS requirements to protect all sensitive data and processes related to payment card transactions.

Even with the deployment of a P2PE solution, merchants must assess their environments for any other vulnerabilities and must follow applicable PCI DSS requirements to ensure that they are handling cardholder information safely. Validation of compliance is necessary to confirm that the security measures are properly implemented and that the merchant is adhering to a complete set of PCI DSS standards, thus maintaining the trust of customers and issuers alike.

This requirement applies broadly to all merchants, regardless of the type of transactions they process, which is why the notion that only certain transactions or e-commerce transactions would require validation does not hold in this context.
