A national payments infrastructure operator relied on AppSentinels to protect critical money-movement APIs powering hundreds of banks and payment applications. By applying runtime business logic protection, the operator detected and blocked abusive behavior in real time while maintaining the speed, fairness, and integrity of the payment rails.
Key Challenges
- Partner Abuse Hidden in Valid Traffic: Aggressive retry and reversal patterns by some participants degraded rail performance and created unfair advantages, despite every API call appearing legitimate.
- Threats Targeting Money-Movement Logic: Attackers continuously probed payment workflows for authorization, ownership, and sequencing weaknesses that traditional controls could not detect.
- Country-Scale Transactions with Zero Margin for Error: Protecting 650M+ daily transactions required precise, real-time enforcement without disrupting legitimate payments.
