Case Study: Seven Bank achieves real-time financial crime detection and streamlined operations with Splunk Cloud

Seven Bank Fights Financial Crimes With Real-Time Log Correlation and Analytics

Seven Bank, Ltd., a major Japanese bank that opens about 17,000 new accounts monthly and operates over 24,000 ATMs, faced rising online transaction risk and complex security requirements. Its existing approach—siloed, manual monitoring of cash and internet activity—prevented log correlation across systems, slowed fraud response, and made unauthorized-access control and scalable operational analysis difficult as the business grew.

The bank adopted Splunk Cloud to centralize logs from internet banking, transaction data, call records and other sources, enabling real-time correlation, behavioral analysis and score-based alerts. The solution delivered faster anomaly and outage detection, prevented unauthorized access and illegal transfers, automated many manual tasks, halved training time, maintained service levels without adding staff, improved staff morale, and created a foundation for further automation such as automatic account freezes and transfer blocks.
