SaaS PCI Compliance Benchmark

PCI DSS applies to any SaaS company that stores, processes, or transmits cardholder data, or provides services that could impact the security of their customers' cardholder data environments. Most SaaS platforms handling billing fall under SAQ-D (Service Provider) requirements.

SAQ-D for Service Providers is the most common questionnaire for SaaS companies (52%), followed by SAQ-A-EP for those using third-party payment pages but hosting their own website (28%). Enterprise SaaS platforms processing over 300,000 annual transactions typically require a full Level 1 ROC.

Multi-tenancy is one of the biggest PCI scoping challenges for SaaS platforms. If any tenant stores cardholder data, the entire shared infrastructure may be in-scope unless robust logical separation controls are demonstrated. Network segmentation documentation and penetration testing across tenant boundaries are typically required.

SaaS companies average 67% evidence automation — the highest of any industry segment. Their cloud-native architectures integrate well with automated compliance tooling, and engineering-led cultures mean security controls are often instrumented from the outset rather than retrofitted.
