Major U.S. Bank Eliminates Unknown Sessions and Saves Downstream Fraud Detection Costs

One of the largest and most established U.S. financial institutions faced dual bot-related threats: significant account takeover attacks compromising consumer accounts and increasing volumes of unknown sessions driving costly downstream fraud analysis.

THE CHALLENGES

Persistent Account Takeover Attacks: Massive bot-based ATO attacks compromised consumer accounts despite layered security with Akamai and LexisNexis ThreatMetrix, eroding customer trust.
Unknown Session Crisis: Increasing volumes of unknown sessions (blank session IDs with no profile information) created material risk and prevented accurate traffic assessment, while operational costs skyrocketed.
Downstream Data Pollution: Junk data from unknown sessions flooded existing security tools, reducing effectiveness of the security stack.

THE ARKOSE TITAN SOLUTION

Strategic Stack Positioning: Deployed Arkose Titan platform between Akamai and ThreatMetrix at top-of-funnel stages (sign-in, sign-up), bridging gaps in existing security infrastructure and reducing costly risk analysis on irrelevant data.
Comprehensive Risk Monitoring: Leveraged nearly 1,000 detection signals using progressive device and behavioral fingerprinting to detect account takeover, credential stuffing, fake account creation and phishing threats before impact.
Adaptive Challenge-Response: Deployed intelligent challenge suite to determine user authenticity, classifying and triaging traffic based on risk profile.
