  • •Network architecture review and documentation
  • •System inventory and classification based on PCI DSS scoping guidance
  • •Network segmentation design and implementation
  • •Segmentation testing methodology development
  • •Implementation of network access controls between segments
  • •Development of scope management procedures

Outcomes & Results
  • •Reduced PCI DSS scope by 65% through effective network segmentation
  • •Decreased the number of in-scope systems from 450 to 158
  • •Implemented clear network segmentation with strict access controls
  • •Developed comprehensive data flow documentation for all cardholder data
  • •Created automated segmentation testing process to validate controls
  • •Reduced annual compliance assessment costs by approximately $175,000
  • •Decreased remediation effort by focusing security controls on truly in-scope systems
  • •Established sustainable scope management process integrated with change management
Key Insights & Lessons Learned
  • •Early stakeholder engagement is critical for successful PCI DSS initiatives to ensure buy-in and alignment with business objectives.
  • •A risk-based approach to implementation allows for more efficient resource allocation and prioritization of activities.
  • •Clear documentation and evidence collection processes are essential for successful PCI DSS assessments.
  • •Integration with existing business processes is essential for sustainable compliance programs.
  • •Continuous monitoring and testing are key to maintaining compliance between formal assessments.
