Fintech Mobile Wallet & Zero-Trust Mesh
Next-gen biometric mobile banking client with real-time settlement and HSM-backed tokenization.
Project Description
Bank-Grade Encryption
Facing stringent regulatory mandates and escalating threat vectors across public mobile communication networks, the client needed a flagship consumer banking application engineered with zero-compromise security.
Citi Solution architected a zero-trust mobile banking platform integrating biometric device authentication, hardware-backed tokenization, and end-to-end mutual TLS encryption with automated anomaly scoring.
The application provides seamless instant settlements while maintaining a 99.999% uptime track record, fully certified for SOC2 Type II, PCI-DSS, and Open Banking regulations.
