PCI-DSS for Retail & E-Commerce
What PCI-DSS means for Retail & E-Commerce organizations — and how we implement it at the architecture level.
Retail and e-commerce businesses that accept payment cards face PCI-DSS obligations that range from simple SAQ A questionnaire compliance (for merchants who fully outsource card processing to a PCI Level 1 service provider) to full QSA assessment (for merchants that handle raw card data directly). The scope of PCI compliance for a retail business is determined entirely by how payment data flows through the commerce architecture — and most commerce platforms that were not built with PCI scope reduction in mind have unnecessary compliance complexity.
PCI-DSS 4.0, released in 2022 and mandatory by April 2025, introduces enhanced requirements for e-commerce specifically: the Script Security requirements of Requirement 6.4.3 mandate that all JavaScript on payment pages be authorized, integrity-checked, and documented — a requirement that substantially affects how analytics, A/B testing, and third-party widget scripts are managed on checkout pages. Retailers that use tag managers, third-party payment overlays, or client-side analytics on checkout pages must redesign their script management to satisfy PCI DSS 4.0.
Scope reduction through hosted payment forms or PCI-compliant PSP integration
PCI-DSS 4.0 Requirement 6.4.3 script security for all JavaScript on payment pages
Network segmentation between commerce platform and cardholder data environment
Annual penetration testing and quarterly vulnerability scanning for in-scope systems
Tokenization for stored customer payment methods
We assess PCI scope in the commerce architecture before implementation begins. Checkout page JavaScript is audited against PCI DSS 4.0 Requirement 6.4.3 requirements and script inventory documentation is built into the deployment pipeline. Tokenization for stored payment methods is designed as a standard component. Where QSA assessment is required, we build evidence generation into the deployment process.
