- Real-time risk, security, and production issues
Testing in BFSI is not just about functionality—it is about accuracy, security, reliability, and compliance.
Why BFSI Domain Knowledge Is Important
- Even a small defect can cause huge financial loss
- Strict regulations (RBI, PCI-DSS, AML, KYC, SOX, HIPAA in insurance)
- Heavy dependency on data integrity and audit trails
- Systems run 24/7 with zero downtime tolerance

- Customer onboarding & KYC
- Account / policy / product creation
- Transactions or premium payments
- Interest, charges, or claim processing
- Settlement & reconciliation
- Statements, reports, and compliance checks
- Audits & regulatory reporting
