Case Study: A U.S. financial services provider cuts manual fraud reviews by 90%+ with Sardine
Key results
The challenge
A U.S. financial services provider relied on manually vetting 100% of new account enrollments, creating a bottleneck in which analysts processed roughly 1,200 accounts and legacy rules carried false-positive rates close to 100%. The reactive, batch-oriented approach could not keep pace with automated attacks.
The solution
The company adopted Sardine's device intelligence, real-time risk scoring, and investigator toolset, optimizing 400+ rules across nearly 20 checkpoints and eliminating rules with near-100% false-positive rates. Automated risk scoring now filters low-risk sessions so analysts focus on genuine risk.
The results, in context
The provider reported reducing manual review volume by more than 90%, with fraud reviews falling from around 1,200 to around 100. It optimized more than 400 rules across nearly 20 checkpoints and removed legacy rules that had near-100% false-positive rates.
