Case Study: Dropbox achieves 70% fewer customer interventions and stronger account takeover protection with Arkose Labs

Dropbox Protects Millions of Accounts Using the Arkose Labs Platform

Dropbox, a service with over 600 million registered users worldwide, faced large-scale account takeover and sign-up abuse that made it a prime target for fraudsters. Its legacy spam and step-up authentication solutions created friction for legitimate users while failing to stop automated attacks, so Dropbox turned to Arkose Labs and implemented the Arkose Labs Fraud and Abuse Prevention Platform to better protect accounts without degrading user experience.

Arkose Labs deployed a combination of Arkose Detect (real‑time risk decisioning) and Arkose Enforce (targeted interactive step‑up challenges) to present friction only to high‑risk traffic, reduce reliance on out‑of‑band authentication, and make attacks economically unviable. The Arkose Labs solution stopped abuse of new account registrations, increased resilience to account takeover, and cut intervention rates for customers by 70%, improving good‑user throughput and lowering operational support costs.
