Protect customer PII and card data by validating application exposure and watching the payment page where third-party scripts can create client-side skimming risk.

Security context

Why retail and ecommerce needs proof

Ecommerce security extends into the customer's browser. Checkout pages often load scripts from merchant code, payment services, analytics, marketing and other third parties. A compromised or unauthorized script can read card data while the legitimate transaction continues normally. Customer PII and card data are the crown jewel, and PCI DSS 4.0 makes payment-page script control and unauthorized-change detection a direct security requirement.

Priority validation areas

  • Monitor payment-page scripts and changes relevant to PCI DSS 4.0 requirements 6.4.3 and 11.6.1.
  • Inspect suspicious client-side behavior around sensitive checkout fields.
  • Audit browser controls such as CSP and SRI where relevant.
  • Validate application, API and credential exposure around ecommerce systems.
  • Preserve evidence and re-test remediation.
  • Keep PCI support framed as testing and evidence, not certification or QSA activity.

Stop assuming you are secure. Prove it.

Continuously test what an attacker can actually reach across your applications, SaaS identities, internal infrastructure and AI systems.
