FINTECH / ACCOUNT & PAYMENT SECURITY
Secure financial workflows across mobile, APIs and cloud.
For financial software and fintech teams handling account access, sensitive records, payment integrations and cloud-dependent products.
SYSTEM RISK / REAL FAILURE CONDITIONS
The boundary is the problem.
A legitimate session must not allow cross-account access, unauthorized transfers, account recovery abuse or compromised support workflows. Risk controls belong at each transaction and data boundary.
TRUST FLOW / ILLUSTRATIVE ARCHITECTURE
- 01Authenticated customer or workforce session
- 02Account, beneficiary and operation authorization
- 03Payment-service and data-provider integrations
- 04Audit, alerts, idempotency and reconciliation
Reference architecture / representative request flow.
NEGATIVE-PATH VERIFICATION
What we'd test
- Cross-account record or balance request
- High-impact action without the required approval

EXPECTED PROJECT OUTPUTS
What the team receives
- Risk-focused architecture and permission map
- Authorization and session test scenarios
- Prioritized remediation or implementation plan
- Release, observability and handoff guidance
Scope, access, deliverables and acceptance conditions are agreed before work begins.
