SOC 2 Audits for Fintech Companies
Banks, payment partners, and enterprise finance teams treat a SOC 2 report as table stakes before they connect to your APIs or move money through your platform. Here is how fintech companies actually scope the audit — criteria, controls, pairings, and cost.
Why fintech companies get asked for SOC 2
Fintech sells into the most compliance-conscious buyers in software: banks running vendor risk programs mandated by their regulators, payment networks with their own certification regimes, and enterprise finance teams whose auditors ask about downstream vendors. A bank partnership or BaaS relationship almost always includes a due-diligence questionnaire where a current SOC 2 Type 2 is the expected answer, not a differentiator.
The data at stake raises the bar: account numbers, transaction histories, KYC documents, and credentials for open-banking connections. When a security review goes deep, reviewers want evidence that money movement and ledger integrity are controlled — which is why fintech is one of the few categories where the Processing Integrity criterion regularly enters scope instead of staying theoretical.
Trust Services Criteria focus for Fintech
Security (the Common Criteria) is mandatory in every SOC 2 report. The other four criteria are elective — you scope them in based on what your customers actually rely on. Here is how fintech companies typically scope them, and why:
| Criterion | Typical scope | Why it matters in Fintech |
|---|---|---|
| Security | Always in scope | Mandatory in every SOC 2. For fintech, expect scrutiny on access to production ledgers, secrets management for banking APIs, and change control around money-movement code paths. |
| Availability | Usually in scope | Payment flows and account access are uptime-sensitive; bank partners often carry contractual SLAs that your report is expected to support with tested failover and incident evidence. |
| Confidentiality | Usually in scope | Transaction data, KYC files, and partner-bank agreements are confidential by contract. Reviewers look for classification, encryption, and retention controls over financial records. |
| Processing Integrity | Common | Rare in most SaaS, common in fintech: buyers moving money through your system want evidence that transactions are complete, accurate, and reconciled — ledger controls, idempotency, and reconciliation jobs. |
| Privacy | Sometimes | Scoped in when you hold consumer financial data subject to GLBA-style commitments. Many B2B fintechs handle it contractually instead and leave the Privacy criterion out of the report. |
Each elective criterion adds controls and evidence — and cost. Scope what your customers demand in security reviews, not everything at once.
Scoping decisions specific to Fintech
These are the Fintech-specific calls that shape your system description, control list, and ultimately your audit price. Settle them before you request quotes — firms price scope, not industry labels.
Draw the boundary around money movement
Decide whether the audited system includes the full payment or ledger path or only the customer-facing platform. Excluding a core money-movement service your partners rely on invites hard questions in bank due diligence — align the boundary with what partners actually consume.
Sponsor banks and processors as subservice organizations
Your BaaS provider, sponsor bank, card processor, and cloud host are typically carved out as subservice organizations. Map which commitments (settlement, uptime, data protection) depend on them, and document the complementary controls you rely on them for.
Reconciliation and ledger integrity evidence
If Processing Integrity is in scope, auditors sample reconciliation runs, exception queues, and correction workflows. Automate daily reconciliations and keep exception logs — manual spreadsheet reconciliation is where fintech audits lose weeks.
KYC/AML vendor stack in the system description
Identity verification, sanctions screening, and fraud vendors process regulated data on your behalf. Decide which appear in the system description and collect their SOC 2 or equivalent reports before your own audit starts.
Segregation of duties in a small team
Bank partners expect the person who writes money-movement code not to approve and deploy it alone. Small fintechs pass this with enforced peer review, deploy gates, and break-glass logging rather than headcount.

Frameworks fintech companies pair with SOC 2
SOC 2 is rarely the only requirement in this category. These are the frameworks most often pursued alongside it — and overlapping evidence you can reuse if you plan both from the start:
| Framework | Why it comes up alongside SOC 2 |
|---|---|
| PCI DSS | Required the moment you touch cardholder data. Scope your CDE tightly (or use a tokenizing processor) and reuse network segmentation, access control, and logging evidence across both audits. |
| ISO 27001 | Comes up when fintechs expand to European banks and partners who ask for certification rather than attestation. The control overlap is large; many firms run both engagements on one evidence base. |
| Penetration testing | Bank due-diligence questionnaires ask for a recent independent pen test alongside the SOC 2. Timing it just before the observation window closes lets one test serve both requests. |

SOC 2 for Fintech: common questions
Do fintech companies need SOC 2 Type 1 or Type 2?
Bank partners and enterprise buyers almost always want Type 2, which covers operating effectiveness over an observation window (typically 3–12 months). A Type 1 is a useful bridge when a partnership is blocked on paperwork now — many fintechs do a Type 1 first, then convert to Type 2 on the same control set.
Should a fintech include Processing Integrity in its SOC 2?
If partners rely on your platform to move money or maintain a ledger, expect the question in due diligence. Including Processing Integrity adds reconciliation and transaction-accuracy controls to the audit, which costs more but often ends recurring security-review friction. If you only display financial data, Security plus Confidentiality usually suffices.
Does SOC 2 satisfy our sponsor bank's vendor requirements?
It is usually the anchor document, not the whole answer. Sponsor banks typically layer their own questionnaires, pen-test requirements, and sometimes on-site or virtual reviews on top of SOC 2. A current Type 2 with clean money-movement controls shortens that process significantly.
How is a fintech SOC 2 priced differently?
Auditors price scope, not the word fintech: an extra criterion like Processing Integrity, more in-scope systems, and more subservice organizations each add testing hours. A fintech scoping three or four criteria will generally pay more than a single-criterion SaaS of the same headcount — get quotes for your actual criteria mix rather than assuming an industry premium.
