PCI DSS vs SOC 2

If you take card payments AND sell to enterprises, you need both. PCI DSS is prescriptive (12 numbered requirements applied to a defined CDE); SOC 2 is principles-based (Trust Service Criteria with auditor judgment). Most fintechs do both. Side-by-side + free audit for each.

Where they diverge

Unique to PCI DSS v4.0.1

  • Cardholder Data Environment (CDE) scoping diagram + asset inventory
  • PAN truncation / masking / tokenization requirements
  • Quarterly external ASV scans (Approved Scanning Vendor)
  • Annual penetration test + segmentation testing
  • Customized approach option requires Targeted Risk Analysis (TRA)
  • Payment-page script integrity monitoring (Req. 6.4.3, 11.6.1) — v4.0
  • Anti-phishing controls + DMARC (v4.0)
  • SAQ-A / B / C / D / P2PE-HW etc — type depends on payment architecture

Unique to SOC 2

  • Trust Service Criteria selectable: Security + optional Availability / Confidentiality / PI / Privacy
  • Auditor judgment-based — design + operating effectiveness
  • Service organization perspective with subservice org carve-out/inclusive method
  • Type 2 = continuous evidence over the audit window
  • Customer Trust Center / Vanta / Drata / Secureframe ecosystem
  • Report shareable under NDA — no public certificate
  • Broader scope: entire production environment + corporate IT, not just payments

Which one do I need?

Do you display Stripe Checkout / PayPal redirect — no card data ever touches your servers?

SOC 2

You're SAQ-A (lowest PCI tier) — vendor management + policy attestation only. SOC 2 is the meaningful effort.

Do you take cards directly via your own forms, IVR, POS, or call center?

PCI DSS v4.0.1

Full SAQ-D or RoC required. PCI is your top priority — segment the CDE tightly to minimize scope, then add SOC 2.

Are you a payments-adjacent SaaS (billing / subscription / invoicing) selling to enterprises?

PCI DSS v4.0.1 + SOC 2

PCI scope is unavoidable; SOC 2 is what enterprise procurement requires. Combined audits via firms like A-LIGN or Schellman save ~25%.

Are you a fintech / payment processor / acquirer?

PCI DSS v4.0.1 + SOC 2

PCI Level 1 RoC + SOC 1 + SOC 2 is the standard stack. Some also need ISO 27001 + PCI 3DS + PCI PIN.

Common pitfalls

Assuming SOC 2 covers payments

SOC 2 does NOT replace PCI. Acquirers will fine $5K–$100K/month and revoke processing privileges regardless of SOC 2 status.

MFA only for admins (PCI v4.0 broke this)

v4.0 mandates MFA for ALL access into the CDE — every individual user, not just sysadmins. Deadline already passed (March 31, 2025). SOC 2 lets you scope this; PCI does not.

Storing CVV/CVC2 anywhere — even encrypted

Req. 3.2 prohibits storing sensitive authentication data after authorization, period. Found in app logs, email order confirmations, and call recordings on most first-time audits.

FAQ

Can I use one auditor for both?

Yes — many QSAs are also AICPA-licensed for SOC 2. A-LIGN, Schellman, Coalfire, Truvantis offer combined engagements with shared evidence. Saves 20–30% vs separate audits.

Does reducing PCI scope help SOC 2?

Yes — scope reduction (tokenization, P2PE, full redirect) reduces both PCI and SOC 2 effort. Same network/access/logging controls cover both.

What's the cost stack?

SAQ-A self-assessment + SOC 2 Type 2: ~$30K–$60K/year. RoC (Level 1) + SOC 2 Type 2: ~$80K–$200K/year. Add ~$50K–$150K internal effort first time.
