PCI DSS 4.0.1 is now fully mandatory, and SOC 2 Type II is table stakes for closing enterprise and bank-partnership deals — but most fintech startups underestimate both the scope and the timeline. This checklist walks through what actually needs to be in place before you can credibly tell a partner, investor, or auditor that you're compliant.
Who this is for: fintech founders, engineering leads, and compliance owners preparing for a SOC 2 audit, a PCI DSS assessment, or a bank/payment-processor partnership review.
Before You Start
- [ ] Confirm your actual scope: do you store, process, or transmit cardholder data directly, or does a processor (Stripe, Adobe Commerce Payments, etc.) keep it out of your environment?
- [ ] Pick your SOC 2 Trust Services Criteria — Security is mandatory; most fintechs also scope in Availability, Processing Integrity, Confidentiality, and Privacy
- [ ] Decide between SOC 2 Type I (point-in-time) and Type II (observed over 3–12 months) based on what your partners actually require
- [ ] Inventory every third party with access to customer or transaction data — cloud providers, KYC/AML vendors, payment processors, background-check services
PCI DSS 4.0.1 Requirements Checklist
- [ ] Cardholder data encrypted at rest and in transit
- [ ] Access control implemented on a least-privilege basis, with role reviews on a defined cadence
- [ ] Vulnerability management program in place, including regular scanning and patch cadence
- [ ] Network segmentation isolating any cardholder data environment from the rest of your infrastructure
- [ ] Logging and monitoring covering all systems that touch payment data, with alerting configured
- [ ] A documented, current information security policy
- [ ] Regular penetration testing and network monitoring, not just a one-time assessment
SOC 2 Readiness Checklist
| Area | What auditors expect |
|---|---|
| Access control | Documented SSO/MFA enforcement across all systems touching customer data |
| Encryption | Data encrypted at rest and in transit across cloud infrastructure (AWS/GCP/Azure) |
| Change management | Documented procedures for code and infrastructure changes, with approval trails |
| Incident response | A tested Incident Response Plan covering containment, communication, and recovery |
| Vendor management | A vendor inventory plus completed security questionnaires at onboarding and annually |
| Monitoring | Continuous monitoring across infrastructure, not point-in-time snapshots |
| Policies | 20–30 written and adopted policies: access control, incident response, vendor management, data classification, and more |
Realistic Timeline
- Weeks 1–2: Gap assessment against your target framework (PCI DSS and/or SOC 2)
- Weeks 3–8: Close technical and policy gaps — this is usually the longest phase for early-stage teams
- Weeks 8–12: SOC 2 Type I readiness, if you're pursuing Type I first
- 3–6 months: Observation window for SOC 2 Type II (the audit period itself, not prep)
- Ongoing: Annual re-certification and continuous control monitoring
Startups with a clean, segmented architecture from day one can reach PCI DSS compliance in 8–12 weeks; a full SOC 2 Type II cycle for a fintech startup typically runs 6–12 months end-to-end.
Questions to Ask a Development or Compliance Partner
- Have you built systems that reached SOC 2 Type II or PCI DSS compliance before, and can you show evidence (not just claims)?
- How do you architect for network segmentation to keep cardholder data environments isolated?
- What's your approach to access control and audit logging across the stack?
- Do you have experience integrating with core banking systems, KYC/AML vendors, or payment processors under compliance constraints?
- What compliance automation platforms (Vanta, Drata, Strike Graph) do you have experience working alongside, if any?
Red Flags to Watch For
- Treats compliance as a checkbox exercise to pass once rather than a continuous control environment
- Can't explain the difference between SOC 2 Type I and Type II, or which one your partners actually need
- No documented incident response plan or vendor inventory
- Assumes PCI DSS doesn't apply because "a processor handles the cards" without verifying your actual data flow
How to Use This
Run the gap assessment first, before committing to a timeline with investors or partners — most fintech teams underestimate the policy-writing and evidence-collection effort more than the technical controls. If you're evaluating a development partner to help close these gaps, use the questions above as part of your vendor selection process, not as an afterthought once the architecture is already built.
