PCI DSS is the Payment Card Industry Data Security Standard. It sets rules for protecting cardholder data: network security, encryption, access control, and ongoing monitoring. You don’t pass it once and forget. Compliance is continuous. Logs must be reviewed, patches applied, threats detected before they breach.
PHI is Protected Health Information. It includes any data that can identify a patient, tied to medical records, diagnoses, lab results, or billing information. Under HIPAA, PHI must be secure, private, and accessible only to authorized personnel. Encryption and audit trails aren’t optional—they’re baseline requirements.
When PCI DSS and PHI intersect, the stakes multiply. Healthcare organizations that process payments deal with both. That means one system securing card data and health data at the same time. Shared databases, APIs, and integrations must satisfy overlapping compliance checks. Weakness in one area compromises the whole.
