Project Overview & Challenge
NexaCard is a leading digital banking platform processing over 800,000 credit card authorization events per minute. They required a zero-trust compliance architecture to satisfy PCI-DSS 4.0 regulations while protecting user financial data against sophisticated credential stuffing and API tampering.
Technical Solution & Implementation
Haldane's cybersecurity operations team architected a Hardware Security Module (HSM) key management layer combined with cloud-native web application firewalls (WAF) and automated tokenization. All sensitive credit card numbers (PANs) are instantly replaced with cryptographically secure tokens before reaching database storage.
"Haldane's zero-trust implementation enabled NexaCard to achieve 100% PCI-DSS 4.0 compliance audit certification in record time with zero disruption to cardholder checkouts."
