A real-time AI firewall in digital banking
The customer quotes and brand details below are representative content, prepared to show the structure of the template.
The challenge
Models running in customer service were exposed to prompt injection, to leaking personal data, and to answer quality drifting downward over time.
Our approach and integration
We built an intelligent proxy layer in front of the model APIs. A Presidio masking engine redacts sensitive data in flight, and automatic rollback moves traffic to the last stable version within 200 milliseconds if performance drops.
Results and impact
Across more than 30 million live customer interactions: zero security incidents, zero PII leaks.
Malformed and malicious inputs are blocked within milliseconds.
System reliability reached 99.99%.
