AI-Powered Fraud Detection
SecureBank • FinTech
The Challenge
SecureBank was losing millions annually to fraud, with their rule-based detection system missing sophisticated attacks and flagging too many false positives, frustrating legitimate customers.
AED 15M+ annual fraud losses
70% of fraud cases missed by rule-based system
25% false positive rate frustrating customers
Manual review taking 3-5 days per case
Our Solution
We built an ensemble of machine learning models that analyzes transactions in real-time, learning from patterns to detect fraud with unprecedented accuracy.

Business Impact
Measurable results that transformed SecureBank's fraud prevention
AED 50M+ saved annually•95% fraud detection rate•5x ROI in first year
"The AI fraud detection system Otaksi Connect built has been transformative for our security operations. We're catching fraud that would have slipped through our old rules-based system, and our customers are no longer being falsely flagged. The ROI in the first year alone was over 5x our investment."
