Achieving PCI DSS & Regulatory Compliance for a Leading Payment Processing Company

This case study examines how a global payment processing company coordinated PCI DSS requirements with regional privacy, authentication, and financial compliance obligations. High transaction volumes, merchant API integrations, and differing retention requirements created a complex operating environment. The engagement brought security and compliance teams together to define scope, map overlapping controls, and address payment risks. Key areas included:

• Payment infrastructure scope and cross-regulatory control mapping
• Merchant API authentication and encrypted transaction channels
• Tokenization, data classification, and regional retention policies
• Transaction fraud monitoring and stronger payment authentication
• Security testing and centralized compliance reporting
• PCI DSS assessment and ongoing compliance reviews

The company achieved PCI DSS certification and established a more coordinated compliance framework. The case study highlights how shared controls, regional policies, and continuous monitoring helped reduce duplicated audit effort, strengthen transaction security, and support merchant confidence across markets.
