Common Questions

Frequently Asked

We implement PCI-DSS Level 1 compliance from day one, including network segmentation, encryption of cardholder data, tokenization, regular vulnerability scans, and penetration testing. Our architecture minimizes PCI scope by using tokenized payment flows and certified third-party processors where appropriate.

Our payment systems achieve sub-100ms transaction processing with real-time fraud detection. We use event-driven architectures, in-memory processing for hot paths, and optimistic concurrency control to maintain speed without sacrificing consistency or security.

We build compliance as a configurable layer that adapts to different regulatory regimes. Whether it's PSD2 in Europe, Dodd-Frank in the US, or MAS regulations in Singapore, our systems support multi-jurisdiction compliance with automated reporting and jurisdiction-specific KYC/AML workflows.

We implement defense-in-depth security including ML-powered fraud detection, real-time transaction monitoring, behavioral biometrics, encryption at rest and in transit, hardware security modules for key management, and immutable audit logs. Our zero-trust architecture ensures no single point of compromise.
