THE CHALLENGES

Phishing and Vishing at Scale: Fraudsters sent fake texts, emails and phone calls impersonating the platform to harvest credentials and hijack accounts — a direct threat to millions of users' financial assets.
Inability to Identify Compromised Accounts: The platform couldn't reliably distinguish legitimate logins from attackers using phished credentials, resulting in a 90% false positive and 80% false negative rate.
Internal Teams Overwhelmed: The volume and sophistication of attacks exceeded what internal security teams could manage, creating dangerous operational gaps.

THE ARKOSE TITAN SOLUTION

Full-Platform Deployment: Arkose Titan was implemented across web and mobile app flows, classifying traffic in real time and surfacing actionable intelligence to the client's security teams.
Phishing Detection via Token Intelligence: Arkose Labs tokens tracked and identified phishing attempts in real time — including token replay attacks — and extended protection to API endpoints such as customer support.
Third-Party Aggregator Compliance: Arkose Titan ensured third-party aggregators were operating within policy, closing a previously unmonitored exposure vector.
Ongoing Tuning Partnership: The Arkose Labs SOC worked closely with the client to continuously adapt defenses as traffic patterns and attacker tactics evolved — replacing a failed in-house build initiative entirely.
