Overview

Vistra’s Global Expansion Platform is now PCI DSS SAQ‑A compliant, affirming our commitment to world-class data security standards in the handling of payment-related activities. This milestone complements our existing ISO 27001 certification and enhances trust in our payment infrastructure.

🚀 Key Takeaway: Our platform now meets stringent global standards for secure payment processing—ensuring data protection, compliance, and peace of mind for all clients engaging in payment workflows.

What is PCI DSS SAQ‑A?

PCI DSS (Payment Card Industry Data Security Standard) is the global benchmark for safeguarding payment card data.

SAQ‑A applies to service providers that do not store, process, or transmit full cardholder data but support merchants through hosted, redirect, or outsourced services. Achieving SAQ‑A compliance confirms that our platform and associated processes maintain rigorous controls to protect cardholder data.
