Direct End-to-End Encryption (DirectE2EE) and PCI Validated P2PE are two closely related terms. DirectE2EE refers to data that is encrypted at the point of interaction (POI) and decrypted outside of the Point of Sale environment (at the processor). DirectE2EE utilizes proprietary encryption format specific to each processing platform.
PCI Validated P2PE is similar to DirectE2EE, but with PCI Validated P2PE there are more procedures in place to help reduce PCI Scope requirements for merchants. Both DirectE2EE and PCI Validated P2PE are secure because they encrypt sensitive data and make it unusable to environments outside the credit card processor's host.
