Cloud consulting for financial institutions
Financial services cloud transformation demands partners who can navigate complex regulatory landscapes while delivering modern, scalable infrastructure. PCI-DSS compliance, SOC 2 attestations, data residency requirements, and low-latency architectures are table stakes — not nice-to-haves.
The firms below have documented experience with banking core system migrations, payment processing platforms, trading infrastructure, and regulatory compliance automation. They understand the intersection of cloud technology and financial regulation.
Regulatory criteria for a financial-services cloud partner
A cloud consulting partner that works fine for a SaaS startup can be a liability at a bank. US financial institutions answer to a layered compliance stack — GLBA, FFIEC examination guidance, PCI DSS, and in some cases SEC and FINRA rules — and examiners hold the institution accountable for its vendors, not just its own controls. Before you shortlist a firm, verify it clears the following bar.
GLBA Safeguards Rule — vendor oversight is your obligation
The FTC's expanded Safeguards Rule (16 C.F.R. Part 314, effective June 2023) requires financial institutions to maintain a Written Information Security Program and to document oversight of every service provider that accesses customer information. "The cloud provider handles it" is not an acceptable control under the shared-responsibility model. Your consulting partner must help you map which controls you own, which the hyperscaler owns, and which fall in the gap — and produce evidence that the gap is closed. A SOC 2 Type II report from the partner is the recognized artifact for satisfying the vendor-oversight provision: Type II means controls were audited as operating effectively over 6–12 months, not merely designed correctly (that's Type I). Require Type II.
FFIEC alignment and examiner-ready architecture
Federal examiners from the OCC, FDIC, and Federal Reserve use the FFIEC IT Examination Handbook as their reference. AWS, Azure, and GCP each publish FFIEC control mappings and offer landing-zone accelerators with guardrails pre-configured for banking workloads. A qualified partner should be able to show you which handbook sections its reference architecture addresses and hand you documentation that survives an examination — not reconstruct it after regulators arrive.
PCI DSS v4.0 for payments workloads
If any workload touches cardholder data, PCI DSS v4.0 (mandatory since March 2025) applies in addition to GLBA — not instead of it. The two standards overlap but are not identical. Verify that the partner has completed PCI DSS scoped engagements, not just general cloud security work, and can segment cardholder-data environments cleanly within your cloud design.
Encryption with customer-managed keys
Retaining cryptographic control matters both for regulatory examiners and for limiting blast radius if a provider is compromised. Require that your partner's architecture uses customer-managed keys — AWS KMS, Azure Key Vault, or Google Cloud KMS — so your institution, not the consulting firm or the cloud provider, holds the keys to regulated data.
Contract language that treats compliance as shared responsibility
The engagement contract itself is an examiner artifact. It should specify the security controls each party owns, breach-notification timelines consistent with GLBA's 30-day rule, and your right to audit the partner's controls. Firms that resist right-to-audit clauses are a red flag.
Evaluation checklist
- SOC 2 Type II report current (issued within the last 12 months)
- FFIEC IT Handbook control mapping available for their reference architecture
- Documented experience with GLBA WISP implementation and vendor-oversight documentation
- PCI DSS v4.0 scoped engagement experience if payments workloads are in scope
- Customer-managed key (KMS/Key Vault) architecture as the default, not an option
- Contract includes right-to-audit, breach-notification timelines, and explicit control ownership table
- Named regulated-industry references — not "financial services experience" in general
Our evaluation methodology treats regulated-industry experience and documented compliance posture as distinct dimensions precisely because a strong general cloud resume does not substitute for this credential stack.
What compliance requirements matter for financial services cloud? +
Key requirements: PCI-DSS for payment processing, SOC 2 Type II for operational controls, FFIEC guidance for banking, state-specific regulations (NYDFS 500, CCPA), and SEC/FINRA rules for investment firms. A qualified partner should have pre-built compliance architectures for these frameworks.
How should financial services cloud proposals be compared? +
Give each finalist the same workload inventory, regulatory constraints, service levels, and responsibility matrix. Compare inclusions, exclusions, delivery roles, evidence requirements, and pricing model before comparing headline fees.
Which cloud platform is best for financial services? +
There is no universal winner. Compare each workload's data residency, identity, integration, availability, service, and regulatory requirements against the current capabilities of AWS, Azure, and Google Cloud, then document the decision and residual controls.
Can banks really move core systems to the cloud? +
Some banking workloads can move to public cloud, but the decision is workload-specific. Map regulatory obligations, data location, recovery requirements, dependencies, operating ownership, and exit conditions before selecting a migration approach.
