Achieving PCI DSS Compliance for a Subscription-Based Service Provider

This case study details how a subscription-based digital service provider addressed PCI DSS gaps in recurring billing, payment retry logs, and customer support workflows. Card data retained in logs and excessive support-agent access increased exposure, while weak account security contributed to fraud concerns. The engagement focused on protecting payment information while preserving the subscription experience. Key areas covered included:

• Payment tokenization and removal of locally retained card data
• Log redaction, encryption, and access audit trails
• Masked card views and restricted support-agent access
• Stronger authentication and suspicious-login monitoring
• Transaction authentication and subscription fraud controls
• Security testing, compliance assessment, and staff training

The provider achieved PCI DSS compliance after remediation and formal assessment. By embedding log reviews, support-session monitoring, and security awareness into routine operations, the organization established a stronger foundation for secure recurring payments and ongoing compliance.
