Point-to-Point Encryption (P2PE)

Point-to-Point Encryption (P2PE) is a formal payment security standard defined and validated by the PCI SSC (PCI Security Standards Council) that encrypts cardholder data from the moment a card is read at a payment terminal until it reaches a secure, validated decryption environment, with no point in between where the data exists in plaintext. It is a specific, certified implementation of End-to-End Encryption (E2EE) designed for card-present payment environments.

The PCI SSC maintains a list of validated P2PE solutions, hardware, software, and operational configurations that have been assessed by a P2PE Qualified Security Assessor (QSA) and certified as meeting the P2PE standard. Using a PCI-validated P2PE solution provides merchants with a formal, recognized path to PCI scope reduction: because cardholder data is never present in plaintext in the merchant's environment, the point-of-sale system, surrounding network, and other merchant infrastructure are largely removed from PCI scope. Merchants using validated P2PE solutions may qualify for a significantly reduced SAQ, SAQ P2PE, rather than the more burdensome full SAQ D.

P2PE addresses a specific threat in card-present environments: malware or other attacks on point-of-sale systems that capture card data from memory or in transit within the merchant's environment. By encrypting data at the terminal before it enters any merchant-owned system, P2PE removes the commercial value of attacking those systems for cardholder data.

P2PE is most relevant for merchants with physical point-of-sale environments, retail stores, restaurants, hospitality businesses. For e-commerce and card-not-present merchants, equivalent protection is achieved through Hosted Payment Pages, iFrame-based card collection, and Tokenization, which prevent cardholder data from touching merchant servers in the first place.
