PCI DSS vs SOC 2: Overlap, Differences, and Doing Both

PCI DSS vs SOC 2

Overlap and Doing Both

Logging and monitoring, access control, change management, vulnerability management, and incident response often produce evidence reusable across both programs when scoped carefully - but requirement IDs and testing procedures differ. Payment processors, gateways, and fintech SaaS that handle or impact card data and sell to enterprises that require SOC 2 typically need both. Define PCI scope first (non-negotiable for card acceptance), then align the SOC 2 system description and TSC selection so evidence collection is not duplicated blindly.

Frequently Asked Questions

Can SOC 2 replace SAQ A?

No. Acquirer and brand PCI validation remains separate from SOC 2 customer assurance.

Is Security the only Trust Services Criterion required?

Security (common criteria) is the baseline category for typical SOC 2 engagements; other TSC are included when relevant to the service and report scope.

Type I or Type II for PCI customers?

PCI DSS does not use Type I or Type II. Customers asking for SOC 2 usually want Type II covering a period.
