SOC 2 vs PCI DSS
Side-by-side benchmark comparison of Trust Services Criteria vs payment card compliance requirements
SOC 2 vs PCI DSS — Side-by-Side
Key framework attributes compared across scope, cost, certification, and compliance approach.
| Attribute | SOC 2 | PCI DSS |
|---|---|---|
| Standard Body | AICPA (American Institute of CPAs) | PCI SSC (Payment Card Industry Security Standards Council) |
| Scope | Service organisation controls for customer trust | Payment card data environment (CDE) |
| Framework | Trust Services Criteria (5 TSC categories) | 12 mandatory requirements |
| Approach | Principle-based — attestation to criteria | Prescriptive — specific technical requirements |
| Avg Cost | $118k/year (Type II) | $169k/year |
| Avg Hours | 740h/year | 953h/year |
| Output | SOC 2 Type I or Type II Report | Report on Compliance (ROC) or SAQ |
| Mandatory | Voluntary — market-driven by buyer requirements | Mandatory for card payment processors |
| Review Cycle | Annual Type II (3–12 month observation period) | Annual assessment + quarterly scans |
| Overlap | TSC Security overlaps with PCI DSS Req 1, 6, 8, 10, 11 | Req 7–11 overlap with TSC CC controls |
3 Key Differences
Trust Services Criteria vs 12 Requirements
SOC 2 is built around five Trust Services Criteria: Security, Availability, Processing Integrity, Confidentiality, and Privacy. Organisations select which TSC categories are relevant to their service commitments. PCI DSS mandates all 12 requirement families for any organisation in scope, regardless of risk profile.
Service Organisation Controls vs Payment Data Protection
SOC 2 attests to the design and operational effectiveness of controls relevant to customer-facing service delivery. It answers the question: "Can this vendor be trusted with our data?" PCI DSS answers: "Does this organisation adequately protect payment card data?" The audiences are different — procurement teams vs card brand assessors.
Attestation Report vs Certification
SOC 2 produces an auditor attestation report (reviewed by customer's auditors, not published publicly). PCI DSS produces a Report on Compliance (ROC) or Self-Assessment Questionnaire (SAQ) submitted to the acquiring bank. SOC 2 reports are NDA-controlled; PCI DSS compliance status is verified through acquiring bank relationships.
Control Overlap — TSC Security and PCI DSS
The Trust Services Criteria Security category (CC) overlaps significantly with PCI DSS Requirements 1, 6, 8, 10, and 11. Organisations with PCI DSS compliance reduce SOC 2 Security TSC preparation effort by approximately 25–35%.
Which Framework Should You Prioritise?
- You process, store, or transmit payment card data
- Your acquiring bank or card brand requires it
- You are a merchant, payment processor, or payments service provider
- Non-compliance means loss of ability to process card payments
- You are a SaaS company selling to enterprise customers
- Customers or prospects are asking for a SOC 2 report during procurement
- You do not process payment card data
- You want to demonstrate security trustworthiness to accelerate sales cycles
Implementing both? SaaS and FinTech companies commonly hold both. Implement PCI DSS first if card payments are in scope, then layer SOC 2 using the TSC Security overlap with PCI DSS Requirements 7–11 to reduce incremental effort by 25–35%.

Run the PCI BenchmarkFrequently Asked Questions
Should I get SOC 2 or PCI DSS compliance first?
If you process payment card data, PCI DSS is mandatory — there is no choice. SOC 2 is voluntary but is increasingly required by enterprise buyers as a vendor qualification requirement. If you are a SaaS company that does not process card payments, SOC 2 Type II is typically the first framework to pursue. If you process card payments and serve enterprise customers, you will eventually need both.
How does SOC 2 overlap with PCI DSS?
The Trust Services Criteria Security category (CC) has the strongest overlap with PCI DSS. CC6 (Logical and Physical Access Controls) overlaps with PCI DSS Requirements 7–8; CC7 (System Operations) overlaps with Requirements 10–11; CC9 (Risk Mitigation) overlaps with Requirement 12. Organisations with PCI DSS compliance reduce SOC 2 Security TSC effort by approximately 25–35%.
Which is more expensive — SOC 2 or PCI DSS?
PCI DSS averages $169k/year vs SOC 2 Type II's $118k/year cross-industry. PCI DSS is more expensive due to mandatory QSA engagement (for Level 1 merchants), quarterly vulnerability scans, penetration testing requirements, and a broader mandatory control scope. SOC 2 scope can be limited to the Trust Services Criteria relevant to customer commitments.
Does SOC 2 satisfy PCI DSS requirements?
No. A SOC 2 Type II report does not satisfy PCI DSS compliance obligations. PCI DSS is enforced by card brands (Visa, Mastercard) and acquiring banks as a condition of processing card payments. SOC 2 is an AICPA attestation report relevant to service organisation customer trust. They serve different purposes and audiences, and both may be required.
