First SOC 2 Audit for Fintech Startups: A Step-by-Step Guide
Published · Updated ·11 min read
A fintech’s first SOC 2 engagement starts with customer assurance requirements, payment and data flows, and a defensible system boundary. Reuse relevant evidence from existing security or payment obligations where it applies, while documenting differences. Assign owners for remediation, operating evidence, and auditor coordination before committing to fieldwork dates.
Key Takeaways
- •For the next operating decision, compare compliance for technology companies with managed compliance services.
- •AICPA & CIMA’s SOC overview describes CPA assurance services.
- •Define the system boundary before assuming existing payment controls cover the whole engagement.
For fintech startups — whether building payment processing, lending platforms, banking-as-a-service infrastructure, investment tools, or insurance technology — the first SOC 2 audit is frequently the compliance milestone that unlocks bank partnerships, enterprise customer contracts, and institutional investor confidence.
Unlike general SaaS companies where SOC 2 is one of several possible compliance frameworks, fintech startups face a market where SOC 2 Type II is functionally mandatory: bank partners require it before sharing customer financial data, enterprise clients require it in vendor security assessments, and institutional investors evaluate it during due diligence.
The challenge for fintech startups pursuing their first SOC 2 is that financial data sensitivity, regulatory intersections with PCI DSS and state money transmitter requirements, and the specific expectations of bank and financial institution buyers create additional complexity beyond a standard SaaS SOC 2 engagement.
This guide provides a fintech-specific step-by-step checklist for going from zero to a completed first SOC 2 Type II report, covering fintech-specific preparation steps, bank partner requirements, PCI DSS overlap considerations, and a phased timeline from initial planning through report delivery. If this is your team's first encounter with SOC 2 at all, start with our plain-English Startup's Guide to Buying SOC 2.
For the next operating decision, compare compliance for technology companies with managed compliance services. Confirm the work included, the evidence you need, and who will own implementation before committing to a provider.
How should a fintech plan its pre-audit assessment?
Week 1-2: Scoping and Strategy
| Step | Action | Fintech-Specific Considerations |
|---|---|---|
| 1 | Define your SOC 2 system boundary | Include all systems that process, store, or transmit financial data — payment processing APIs, banking integrations, KYC/AML systems, transaction databases, and customer-facing applications |
| 2 | Select Trust Service Criteria | Fintech startups should include Security (required), Confidentiality (strongly recommended for financial data), and Processing Integrity (strongly recommended for financial calculations); Availability if platform uptime is contractually committed |
| 3 | Identify bank partner and regulatory requirements | Survey your bank partners' specific SOC 2 expectations; some require specific criteria or observation period coverage |
| 4 | Determine PCI DSS overlap | If you process, store, or transmit cardholder data, assess PCI DSS requirements alongside SOC 2; plan for coordinated compliance |
| 5 | Set your target timeline | Work backward from your bank partner deadline or enterprise deal timeline to set your observation period and audit dates |
Week 3-4: Readiness Assessment
| Step | Action | Expected Findings for First-Time Fintech |
|---|---|---|
| 6 | Conduct a readiness assessment | Use your GRC platform's automated assessment or engage an advisory firm for a fintech-specific evaluation |
| 7 | Inventory all financial data flows | Map how financial data moves through your system — from customer input through processing, storage, and transmission to bank partners |
| 8 | Assess current security posture | Evaluate existing controls against SOC 2 criteria; expect gaps in formal documentation, access reviews, and vendor management |
| 9 | Identify remediation priorities | Prioritize gaps that block audit readiness: MFA enforcement, encryption, access controls, change management, incident response |
| 10 | Estimate remediation effort and cost | Budget for remediation: costs vary based on the number and complexity of gaps identified during the readiness assessment |
Common Readiness Gaps for Fintech Startups
| Gap | Why It Is Common | Remediation Priority |
|---|---|---|
| No formal access review process | Startup teams grow quickly; access expands without formal review | Critical — bank partners specifically evaluate access management |
| Incomplete MFA enforcement | Service accounts or legacy accounts without MFA | Critical — any account without MFA is a finding |
| No formal change management | Rapid development without documented approval and testing | Critical — change management is a core SOC 2 control area |
| Missing incident response plan | No formal plan beyond "fix it when it breaks" | High — incident response is required; financial incident scenarios needed |
| No vendor management program | Multiple fintech-specific vendors (banking APIs, KYC providers) without formal assessment | High — fintech has a dense vendor ecosystem that must be managed |
| No formal risk assessment | No documented risk identification and treatment process | High — required by CC3 criteria |
| Encryption gaps | Data at rest not fully encrypted; some API connections not using TLS 1.2+ | Critical — financial data encryption is non-negotiable |
| No security training program | No documented security awareness training for employees | Medium — required but can be implemented quickly |
What should the control implementation stage accomplish?
Week 5-6: Foundational Controls
| Step | Action | Fintech-Specific Details |
|---|---|---|
| 11 | Enforce MFA for all users | Enable MFA on all accounts including service accounts with interactive access; use hardware tokens for production infrastructure access |
| 12 | Implement role-based access control | Design RBAC model with fintech-specific roles: transaction viewer, payment processor, bank integration manager, compliance officer |
| 13 | Configure encryption | Enable encryption at rest for all financial data stores; verify TLS 1.2+ for all API connections; implement field-level encryption for sensitive fields (SSN, account numbers, routing numbers) |
| 14 | Set up logging and monitoring | Deploy centralized logging; enable cloud provider audit trails; configure alerting for security events and financial transaction anomalies |
| 15 | Configure a GRC platform | Set up Vanta, Drata, Secureframe, or Sprinto; connect integrations; begin automated evidence collection |
Week 7-8: Process Controls
| Step | Action | Fintech-Specific Details |
|---|---|---|
| 16 | Formalize change management | Implement branch protection, PR approval requirements, and deployment workflows in your CI/CD pipeline |
| 17 | Create incident response plan | Include financial-specific incident scenarios: unauthorized transactions, payment processing failures, bank API outages, customer financial data exposure |
| 18 | Conduct initial risk assessment | Document risks specific to financial data processing: fraud risk, regulatory risk, bank partner risk, financial data breach risk |
| 19 | Build vendor management program | Inventory all vendors; prioritize banking partners, KYC/AML providers, payment processors; conduct initial vendor risk assessments |
| 20 | Establish access review process | Document quarterly access review procedure; conduct the first access review to establish baseline |
Week 9-10: Documentation
| Step | Action | Fintech-Specific Details |
|---|---|---|
| 21 | Write or customize security policies | Use GRC platform templates; customize for financial data handling, PCI DSS overlap, regulatory requirements |
| 22 | Create financial data handling procedures | Document how financial data is classified, processed, stored, transmitted, and disposed of throughout your system |
| 23 | Document bank integration security | Describe security controls for each bank partner integration: authentication, encryption, access controls, monitoring |
| 24 | Complete system description draft | Draft the SOC 2 system description including fintech-specific components: payment processing, banking integrations, financial data flows |
| 25 | Distribute policies and collect acknowledgments | Deploy policies through your GRC platform; track acknowledgments from all employees |
Week 11-12: Testing and Verification
| Step | Action | Expected Outcome |
|---|---|---|
| 26 | Conduct penetration testing | Engage a penetration testing firm with fintech experience; include API testing for financial endpoints |
| 27 | Run vulnerability scan | Scan all in-scope infrastructure; remediate critical and high findings; document remediation timeline for remaining findings |
| 28 | Verify all controls are operational | Review GRC platform compliance dashboard; confirm all controls show passing status |
| 29 | Test incident response procedures | Conduct a tabletop exercise using a financial-specific scenario (payment fraud, data breach involving financial records) |
| 30 | Verify evidence collection completeness | Confirm automated and manual evidence is being collected for all controls; address any gaps |
PCI DSS Overlap Considerations
When PCI DSS Applies
| Scenario | PCI DSS Applicability | Coordination with SOC 2 |
|---|---|---|
| Your platform processes cardholder data directly | PCI DSS required — you are a service provider under PCI DSS | Significant overlap with SOC 2; pursue both frameworks leveraging shared controls |
| You use a payment processor (Stripe, Adyen) that handles cardholder data | PCI DSS may not apply to you directly; SAQ may be sufficient | Focus on SOC 2; document your payment processor as a subservice organization |
| You store cardholder data (card numbers, CVVs) | PCI DSS required — storage of CHD brings full PCI DSS scope | Full PCI DSS compliance needed alongside SOC 2 |
| You transmit cardholder data to a processor | PCI DSS applies — transmission is in scope | SAQ or full PCI DSS depending on volume; document transmission controls in SOC 2 |
SOC 2 and PCI DSS Control Overlap
Map existing payment-security evidence to the particular SOC 2 system and criteria. Access reviews, change records, and monitoring records may be useful, but the systems, dates, and objectives must match. Confirm suitability with the auditor; a PCI assessment does not substitute for a SOC 2 opinion.

Frequently Asked Questions
How does PCI DSS overlap with SOC 2 for fintech?
Substantially. Encryption, access control, logging, vulnerability management, and vendor oversight satisfy requirements in both, so evidence collected once can serve each — provided you scope and document it to cover both frameworks from the start.
What do bank partners require beyond SOC 2?
Bank partners layer their own diligence on top: a completed security questionnaire, evidence of BSA/AML controls where relevant, business continuity documentation, and often a right to audit. A SOC 2 report shortens that review but does not replace it.
