Implementation of Tokenization for PCI Compliance Using Protegrity at a Leading Financial Firm

Executive Summary: VerticalServe, a prominent consulting company, was engaged by a leading financial firm to implement a tokenization solution using Protegrity to achieve Payment Card Industry (PCI) compliance. The project focused on format preserved masking, tokenization of sensitive data, de-tokenization libraries, audit logs, and utilization in Hadoop, Kafka, and relational databases. The goal was to protect customer data and minimize the risk of data breaches while maintaining compliance with PCI regulations.

1. Project Background and Objectives: The leading financial firm sought to enhance the security and privacy of sensitive customer data while maintaining PCI compliance. The primary goals of the project were:

• Implement tokenization for sensitive data, including Social Security numbers, credit card information, email addresses, and names
• Ensure format preserved masking to maintain data usability
• Develop de-tokenization libraries for client-facing applications
• Create audit logs for sensitive data de-tokenization
• Enable tokenization utilization in Hadoop, Kafka, and relational databases

2. Project Approach: VerticalServe adopted a systematic approach to ensure successful implementation of the tokenization solution:

A. Assessment and Planning:

• Analyzed the financial firm’s existing data architecture and storage systems
• Identified sensitive data elements and their respective flows within the organization
• Developed a detailed implementation plan and timeline

B. Format Preserved Masking and Tokenization:

• Implemented Protegrity’s tokenization solution to protect sensitive data with format preserved masking
• Configured the tokenization policies and rules for various data elements, including SSN, credit card information, email addresses, and names
• Integrated the tokenization solution with existing data processing pipelines

C. De-tokenization Libraries:

• Developed de-tokenization libraries for client-facing applications to access original data when necessary
• Ensured secure transmission of de-tokenized data through encryption and strict access controls
• Conducted thorough testing to validate the functionality and security of the de-tokenization process

D. Audit Logs for Sensitive Data De-tokenization:

• Implemented audit logging for all de-tokenization activities to maintain a comprehensive record of data access
• Configured real-time alerts for any suspicious activity or unauthorized access attempts
• Provided the financial firm with tools to analyze and monitor audit logs effectively

E. Utilization in Hadoop, Kafka, and Relational Databases:

• Integrated the tokenization solution with the financial firm’s Hadoop and Kafka data processing systems for seamless data protection
• Configured Protegrity’s tokenization solution to work with relational databases, ensuring data security across all data storage platforms
• Validated the performance and compatibility of the tokenization solution with the firm’s data ecosystem

3. Results and Benefits: Upon successful implementation, the leading financial firm experienced several benefits, including:

• Enhanced security and privacy of sensitive customer data through tokenization and format preserved masking
• Compliance with PCI regulations, reducing the risk of penalties and reputational damage
• Streamlined and secure data access for client-facing applications via de-tokenization libraries
• Improved visibility and control over sensitive data access through comprehensive audit logs
• Seamless integration with the financial firm’s existing data ecosystem, including Hadoop, Kafka, and relational databases

4. Conclusion: VerticalServe successfully implemented the Protegrity tokenization solution for the leading financial firm, achieving PCI compliance and enhancing the security of sensitive customer data. The implementation not only reduced the risk of data breaches but also streamlined data access processes for client-facing applications. The financial firm now benefits from a robust and compliant data protection solution that safeguards customer information and supports their ongoing business growth.
