Case Study: BoursoBank strengthens fraud protection and preserves customer experience with IBM Security Trusteer

How BoursoBank protects its customers from fraud

BoursoBank, a leader in online banking with more than five million customers, faced a growing fraud threat across nearly 1,000 online features while needing to protect personal data and preserve a smooth customer experience. To address this challenge, it turned to IBM and the IBM Security Trusteer solution.

IBM Security Trusteer analyzes each login and transaction using behavioral and technical signals, threat intelligence, and connection patterns without accessing customer personal data. The result was faster fraud detection, fewer false positives, and stronger prioritization of real threats; BoursoBank reported that some alert types reached a proven fraud rate of up to 97%, enabling quicker action and a better customer experience.
