Top 5 Crypto Exchange Defeats Account, ACH, and Card Fraud with DataVisor

World’s Best-Established Cryptocurrency, a global exchange serving hundreds of thousands of users across dozens of countries, faced escalating ACH and stolen‑card funding fraud, widespread promotion abuse from mass‑registered fake accounts, and account‑takeover risk — all while relying on an unsustainable rules‑only detection system. To scale securely and protect customer experience, they turned to DataVisor’s fraud and risk management platform, seeking a replacement for manual reviews and legacy rule architecture.

DataVisor implemented large‑scale data ingestion, a modern rules engine, a supervised + unsupervised machine‑learning ensemble, and a linkage-based Knowledge Graph for investigations, deploying the solution with minimal downtime and fast integration. The result: 92% of fraudulent account openings blocked before promotion disbursement, automated actions on over 83% of detected cases, a 42% improvement in detection accuracy versus the in‑house system, over $15M annual savings, and a 5–20x uplift in review efficiency — all delivered by DataVisor’s team.
