From Hours to Seconds: Transforming Fraud Detection Efficiency

Fraud detection is critical for any institution, but perhaps none more so than a global credit card provider. This provider, in particular, operates one of the world’s fastest payment networks, connecting consumers, financial institutions, and businesses in more than 210 countries.

The provider prioritizes secure and innovative payment solutions. However, its fraud detection process took an average of 3.5 hours, leaving customers vulnerable to financial losses and frustration.

The company worked with multiple vendors for two years to address the issue, but no solution yielded significant improvement. With millions of transactions processed daily, the organization urgently needed a partner capable of diagnosing the bottlenecks and delivering rapid, scalable results.

The client sought a solution to achieve near-instantaneous fraud alerts without compromising the system’s integrity or usability. They turned to Technology Partners to optimize their systems and improve the customer experience.

The Solution

Technology Partners deployed a query-tuning expert to assess and resolve the system’s performance issues. The approach focused on enhancing database efficiency while providing the client’s team with sustainable tools for long-term improvements.

• Query Optimization: The expert applied advanced techniques such as indexing, SQL hints, histograms, stored outlines, and materialized views to improve query efficiency and response times.
• Mentorship Program: The client’s Oracle DBA team was trained to identify and address future performance issues, ensuring self-sufficiency.
• Sustainable Framework: This approach established a set of tools and strategies that could be applied to other systems to achieve consistent performance gains.

This tailored solution ensured the client could maintain peak system performance and quickly respond to evolving challenges.

The Results

The results were immediate and transformative, with a?600x increase in performance speeds. Fraud detection times dropped from 3.5 hours to just 20 seconds after less than a day of tuning. This dramatic reduction allowed customers to react to fraudulent activity almost instantly, improving trust and satisfaction.

The new tools and strategies implemented by Technology Partners not only resolved the immediate issue but also provided a framework for ongoing optimization. The client’s Oracle DBA team continues to apply these techniques, achieving similar performance improvements across other systems.

This project exemplifies how targeted database optimization can significantly improve operational and customer experience, particularly in high-stakes industries such as financial services.

Final Project Outcomes

• 20-Second Fraud Alerts: Reduced detection times by over 600x, enhancing customer safety.
• Sustainable Optimization: Provided tools and training for ongoing performance improvements.
• Enhanced Customer Experience: Improved trust and satisfaction with faster fraud notifications.
• Scalable Framework: Established a replicable model for optimizing other systems.
