K3DES performs Point to Point Encryption (P2PE) assessments. A P2PE solution encrypts card account data in an approved payment device and the data remains encrypted in the merchant environment and is only is decrypted in special hardware outside the merchant environment.  P2PE is designed to reduce risks of a breach by removing clear cardholder data from merchant processing environments.  P2PE consists of six solution domains that represent the core areas where security controls need to be applied and validated.
