Introduction

In 2023, following the launch of its mobile and internet banking services, a global bank identified the need to strengthen its fraud defenses. We oversaw the product and strategy management for the implementation of a state-of-the-art fraud management system.

The goal was to enhance security measures against login and transactional fraud through the deployment of NetGuardians' renowned fraud detection capabilities. We zeroed in on the platform through a request for proposal (RFP) process.

Challenge

As the bank expanded its digital offerings, it became automatically vulnerable to sophisticated fraud schemes. The existing fraud management infrastructure, based primarily on simple transactional rules and login monitoring, was inadequate for the complexity of modern fraud. This outdated system was not equipped to adapt to new fraud patterns, prompting the need for a dynamic, intelligent solution to protect the bank's expanding digital channels.

Competitive Analysis

In evaluating solutions for the problem at hand, there were a few distinct candidates for our solutioning:

• Enterprise Solutions: Designed for high-scale operations, these platforms cater to large financial institutions. They feature real-time transaction monitoring, machine learning for fraud pattern detection, cross-channel data analysis, and compliance management. Examples like FICO and SAS offer scalable solutions for high transaction volumes, multiple jurisdictions, and various types of fraud, including card-not-present, account takeover, and synthetic identity fraud.

• Mid-Market Solutions: Targeted at medium-sized institutions, these tools balance usability and functionality, featuring rule-based alerts, risk scoring, and machine-learning analytics. Companies like NetGuardians, Fraud.net, and Kount offer customizable platforms that are more cost-effective than enterprise systems.

  
  

• Basic Tools: Designed for small businesses or startups, these tools offer basic transaction analysis, rule-based fraud detection, and user-friendly dashboards. SEON and Riskified provide cost-effective anomaly detection and essential features without the sophistication of higher-tier solutions.

  
  

• Bespoke, Manual Solutions: Custom fraud management systems relying on internal processes, manual reviews, and limited automation. Though less scalable, they provide high customization levels, suitable for organizations dealing with unique types of fraud needing human intervention.

  
  

Process

The process to enhance the fraud management system was comprehensive, with particular emphasis on aligning with the bank’s operational needs, integration challenges and customer experience:

• RFP Study: A Request for Proposal (RFP) study was conducted to evaluate and select the most suitable fraud management solution that could meet the bank’s specific needs. This study was crucial in choosing a system that provided advanced analytical tools and could seamlessly integrate with existing banking platforms. We created a comprehensive feature matrix to align platform capabilities to the Bank's needs.

• Stakeholder Engagement: Workshops and interviews were conducted across various departments including compliance, operations, IT, and customer service to gather insights and establish a clear set of requirements for the new system.

  
  

• User Journey Mapping: Detailed mapping of the fraud management processes was undertaken to understand the data flow and interaction sequences, essential for identifying vulnerabilities and integration points within the customer's journey.

  
  

• Data Point Collection: We identified critical data points necessary for digital and payment fraud detection and compliance, gathering both customer-generated and third-party data to enrich the system’s analytical capabilities.

  
  

• System Customization and Integration: Customization of the selected fraud management system focused on optimizing machine learning models to detect new fraud patterns and integrating these capabilities with the bank’s core banking system and digital banking platforms to ensure real-time data synchronization and alerting.

Solution

Our strategy encompassed the integration of NetGuardians’ fraud management system, equipped with state-of-the-art features to enhance the bank's fraud detection capabilities significantly. We determined that the following components were essential for an end-to-end fraud management system

• Comprehensive Risk Assessments: The system employs advanced analytics and machine learning models to continuously learn and adapt to new fraud patterns. This allows the bank to stay ahead of evolving threats by providing precise risk assessments that adjust to behavioral changes and emerging trends.

• Case Management: NetGuardians’ system includes robust case management tools that leverage 'four-eyes' and 'six-eyes' principles to ensure each alert is rigorously scrutinized. 

  
  

• Customer Profiling: Using AI-driven analytics, the solution profiles customers based on risk factors derived from transaction behaviors, login patterns, and other relevant data. This profiling helps in identifying high-risk activities and allows for targeted monitoring and prevention strategies.

  
  

• Ongoing Monitoring: The system utilizes real-time monitoring capabilities to track and analyze transactions as they occur. This dynamic approach ensures that any suspicious activity is detected instantly, enabling the bank to respond promptly to potential fraud incidents.

  
  

• Custom and Standard Risk Factors: The system is configured with both custom and predefined risk factors, which can be adjusted to the bank's specific requirements. This flexibility allows for enhanced customization of risk thresholds to better align with the bank’s operational risk appetite.

  
  

• Custom APIs: The implementation includes secure, custom APIs designed to integrate seamlessly with the bank’s existing systems. These APIs facilitate efficient data exchange and synchronization across platforms, enhancing the overall effectiveness of the fraud management solution.

Impact

The adoption of NetGuardians fraud management system marked a significant leap forward for the bank:

• Real-time Fraud Detection: The bank could now stop fraudulent transactions as they occurred.

  
  

• Reduced False Positives: The behavioral profiling and AI-driven segmentation led to an 80% reduction in false positives.

  
  

• Operational Efficiency: The intuitive case management and investigative tools optimized the bank's response to fraud alert.

  
  

• Improved customer experience: Seamless integration with online channels enhanced customer experience and security.

Lessons Learned

• Finding the balance between regulation and automation: Creating a fraud management system that excels in the market involves carefully balancing regulatory compliance, lean product development principles, and user needs. Insights from regulatory bodies such as the Financial Conduct Authority (FCA) and Federal Financial Supervisory Authority (BaFin) shaped our strategy to ensure regulatory adherence while developing features that enhance market competitiveness. This approach made our fraud detection solutions both compliant and market-ready.

• Importance of clear processes: Implementing a fraud management tool requires precise process optimization and comprehensive documentation. Tailoring these processes to align with the organization's specific fraud risks and operational workflows is vital. Detailed documentation not only aids in smoother implementation but also results in clear, audit-ready compliance records, which are critical when aligning with industry standards and regulatory requirements.

  
  

• The need for integration mapping: Early identification of integration points and data flows is crucial. This process needs to be initiated early in the project to identify potential bottlenecks and allocate resources efficiently. Clear mapping of data movement across different systems ensures seamless integration and effective collaboration between various departments, allowing for robust fraud detection and accurate risk scoring.

Conclusion

This case study exemplifies the transformative impact of NetGuardians’ fraud management solution on a global bank’s security posture. By leveraging advanced AI models and real-time detection capabilities, the bank significantly improved its fraud detection and prevention mechanisms, safeguarding assets and bolstering customer trust.
