Case Study: a top-5 global processor modernizes $2B-a-day reconciliation with Praxent Decode

a top-5 global processor modernizes $2B-a-day reconciliation with Praxent

The customer, a top-5 global processor, faced a critical challenge with its $2-billion-a-day payment reconciliation system. The legacy Delphi platform was a black box with lapsed licenses, end-of-life hardware, and no remaining institutional knowledge, creating a high risk of permanent failure. The company engaged Praxent, which utilized its PraxentDecode reverse-engineering agent system to understand and document the at-risk system.

Praxent's solution modernized the reconciliation process by reverse-engineering 14,000 lines of code to extract business rules, map data models, and identify security vulnerabilities. The results included a 100x cost reduction compared to traditional modernization, the recovery of 714 business requirements, and a clear, actionable roadmap for rebuilding. This effort successfully unblocked the previously stalled modernization project.
