Wells Fargo - Protecting 100% of transactions in real time

Wells Fargo, the world's second-largest bank by market capitalization and the fourth-largest bank in the U.S. by total assets, uses FICO’s Falcon Fraud Manager, along with Couchbase’s NoSQL database to support its fraud monitoring infrastructure. Wells Fargo applied machine learning analytics to internal and third-party data to identify and adapt to sophisticated fraud attacks in real time. Now, 100% of transactions are processed in real time for fraud - totaling 50+ million transactions per day - at less than 10 ms per operation.
