Compliance by design: Solving bank-grade security with a foundational component

Maryna Rybalko explores how the foundational component concept helps overcome compliance challenges in microservices-based payment platforms. When multiple services handled sensitive cardholder data, duplication and scattered controls increased risk and complexity. When PCI DSS v4.0 was introduced, a Secure Storage component was designed to centralize compliance and ensure secure development by default.

Key takeaways:
• When and how to use a foundational component to address compliance problems
• Advantages of centralized compliance include reduced duplication, lower risk, and faster regulatory updates
• Designing for enterprise banks with built-in auditability, security, and scalability
• Building a developer experience that promotes adoption through clear, intuitive design
