Case Study: Leading Global 500 Financial Services Company achieves $14M fraud avoidance and blocks 75K+ email attacks with Abnormal AI

Global 500 Financial Organization Moves to “Digital Everything” to Enhance Customer Experience and Email Security

Leading Global 500 Financial Services Company, a multinational financial services firm undergoing a “digital everything” transformation, identified email as its most vulnerable attack vector across 34,000+ mailboxes and sought stronger protection against vendor compromise and business email compromise. To close gaps left by existing layers (IronPort and FireEye), the customer engaged Abnormal AI to add behavior-based email security (Abnormal ICES, VendorBase™, and account takeover protection) as a final line of defense.

Abnormal AI’s behavior- and ML-driven solution quickly exposed and stopped sophisticated vendor‑impersonation and socially engineered attacks that were bypassing prior defenses, finding 77 compromised vendors in the first 90 days and detecting ~11,000 advanced attacks per month. Abnormal AI prevented 75,000+ attacks in the first year, helped avoid an estimated $14 million in supply‑chain fraud, and provided automatic remediation that reduced analyst effort and improved overall email security posture.
