Securing PCI DSS Compliance for an Online Merchant Selling Goods with Call Center Integration

This case study examines how an online goods retailer with a customer support call center addressed PCI DSS gaps in checkout and support operations. Local card data retention, full card-number visibility, and application weaknesses created unnecessary exposure. The engagement focused on redesigning payment data handling and restricting access while strengthening the customer-facing platform. Key areas included:

• Tokenization and removal of locally retained payment card data
• Masked card views and role-based access for support agents
• Protected transaction channels and redacted logs
• Stronger customer authentication and suspicious-activity monitoring
• Web application testing and security improvements
• Staff awareness, assessment evidence, and ongoing control reviews

The merchant achieved PCI DSS compliance following remediation and formal assessment. Improved checkout data flows, restricted support access, and continuing security reviews helped protect payment information across online sales and customer service, supporting a more resilient operating environment.
