The Challenge

Legacy Platform Holding Them Back

NovaPay came to us with a critical challenge: their legacy payment platform was struggling to keep up with rapid transaction growth while maintaining security and fraud detection accuracy.

  • 60% increase in transaction volume over 12 months
  • Manual fraud review was slow and error-prone
  • High false-positive rate blocked legitimate transactions
  • PCI-DSS and SOC 2 certification required
The Solution

NovaSecure AI-Powered Fraud Detection Platform

We designed and delivered a production machine-learning fraud detection platform in six months, combining an ensemble model with a real-time feature store ingesting hundreds of behavioral signals.

A human-in-the-loop review interface gave the NovaPay compliance team full visibility into model decisions, with auto-escalation rules for edge cases and a Shapley-value explainability layer generating per-decision rationale for regulatory submissions.
