SOC 2 by industry
SOC 2 for fintech and payments: what bank partners and platform clients expect of your controls
What changes when the service organisation moves money: why sponsor banks and platform clients ask, what belongs in scope, where examiners sample across keys, fraud, reconciliation and regulated releases, and how the report sits beside PCI DSS and SOC 1.
Key points
- For a fintech, the SOC 2 request most often comes through a sponsor bank or banking-as-a-service partner's due diligence, not only from enterprise customers.
- Processing integrity and availability matter more here than in most sectors, because payments, ledgers and loan decisions must be complete, accurate and on time.
- Examiners concentrate on key and secrets management, reconciliation, fraud monitoring and change control over releases that move money.
- SOC 2 does not replace PCI DSS for card data, nor a SOC 1 report where your service affects clients' financial reporting; many fintechs need two or all three.
Why fintech and payments companies are asked for SOC 2
A fintech rarely holds every licence itself. Payment facilitators, lending platforms, wealth apps and card programme managers usually operate through a sponsor bank, an e-money issuer or a banking-as-a-service provider. That partner answers to its own supervisors for the third parties it relies on, so its onboarding and annual review ask for independent assurance over your controls. A current SOC 2 report is the document most partner risk teams already know how to read.
Demand also comes from the other direction. Merchants, marketplaces and platforms embedding your payments or lending API treat you as a critical vendor, and institutional clients of wealth and treasury platforms send the same vendor risk questionnaires a bank would. Where your platform sits inside a client's product, your report may feed theirs as a subservice organisation.
What differs from other technology companies is the consequence of failure. An outage stops settlement, a processing error misstates balances, and a compromised key can move funds. Partners read the report for those risks first.
What sits inside the scope for a fintech
The system description should name the customer-facing application and APIs, the ledger or core processing engine, payment and card processor integrations, the key management service or hardware security modules, fraud and transaction-monitoring tools, reconciliation jobs, the release pipeline and the identity provider controlling access to production. Customer support and operations tooling that can view accounts or initiate refunds belongs inside too.
The sponsor bank, card processor, core banking vendor and cloud provider are usually subservice organisations. Their controls sit in their own reports; you evidence that you review those reports and operate the complementary controls they expect of you. See SOC 2 vendor management and subservice organisations.
Three scope mistakes recur in this sector: describing the app but leaving out the back-office tools that adjust balances or approve payouts; omitting the reconciliation and settlement processes that prove processing was complete; and scoping a single product when the partner is onboarding a new lending or card programme running on different infrastructure. The general rules are in SOC 2 scope: system boundaries, trust services categories and carve-outs.
Where the criteria bite for fintech and payments
| Criteria area | What it means in a fintech | Evidence the examiner samples |
|---|---|---|
| CC6 Logical and physical access | Who can reach production data, signing keys, payout functions and admin consoles, with dual control over sensitive actions | Key generation, rotation and access logs, privileged access reviews, approvals for manual balance adjustments, leaver removal times |
| CC8 Change management | Releases touching pricing, fee logic, interest calculation or payment flows are authorised, tested and approved before deployment | Change tickets with test evidence and independent approval, segregation between developers and production deployers, reviewed emergency fixes |
| CC7 System operations | Anomalies, suspected fraud and security incidents are detected, investigated and resolved | Fraud rule alerts and case records, monitoring dashboards, incident register with partner notifications, post-incident reviews |
| PI Processing integrity | Transactions are complete, valid, accurate, timely and authorised from instruction to settlement | Daily reconciliations to processor and bank statements with breaks investigated, input validation, duplicate-payment checks, exception queues |
| A Availability | The platform meets the uptime and recovery commitments in partner and merchant agreements | Capacity monitoring, failover and recovery test results, status page and incident history against committed service levels |

How SOC 2 sits beside PCI DSS, SOC 1 and partner requirements
If you store, process or transmit cardholder data, PCI DSS applies and is validated separately; a SOC 2 report is no substitute for that validation, which your acquirer or partner will ask for in its own right. One set of access, logging and change controls can support both. See the PCI DSS hub and PCI DSS vs ISO/IEC 27001 and SOC 2.
If clients rely on your service for entries in their financial statements, such as loan servicing balances, payroll disbursements or fund accounting, their auditors may need a SOC 1 report on controls relevant to financial reporting. SOC 2 does not answer that question; see the SOC 1 hub.
Sponsor banks often add contractual requirements of their own, such as audit rights, incident notice periods and annual attestation. Map each one to a control in the same register so a single evidence calendar serves the partner review, the SOC 2 examination and any certification to ISO/IEC 27001.
What a fintech engagement looks like
Duration depends on the partner's deadline, how many products and processors are in scope, whether reconciliation is already automated, and whether card data sits in the environment. The CTO or head of engineering, risk and compliance, finance operations, fraud and whoever owns the bank relationship must be involved. With Design™, Sterling guides your teams to own the controls; with Drive™, Sterling carries more of the documentation, evidence and readiness testing while engineering keeps shipping.

Book a free discovery callSOC 2 for fintech: questions buyers ask
Our sponsor bank asked for SOC 2. Is that enough for their due diligence?
Usually it is the core document, but not the whole review. Most partners also ask about their own contract terms, financial crime controls and business continuity, which the report may only partly cover.
Do we need SOC 2 if we are already PCI DSS compliant?
Often yes. PCI DSS covers cardholder data; SOC 2 covers the wider service, including ledgers, lending data, availability and processing integrity that partners and enterprise clients ask about.
Should processing integrity be in scope for a payments platform?
In most cases yes, because clients rely on payments being complete and accurate. Include it once reconciliations run daily and breaks are investigated with records.
SOC 1 or SOC 2 for a lending or wealth platform?
It depends on who reads it. Clients' financial statement auditors need SOC 1; security and partner risk teams need SOC 2. Platforms serving both often obtain both.
