Meet Your Team: Anti-Fraud Solutions

Industry experts report that 20 percent of global mobile ad spend can be identified as fraud. adjoe s Anti-Fraud team has both validated this number and prevented fraudulent users from entering partners ad spend.

The team s software includes two major components.

1) A distributed backend system that provides different interfaces to partners, modern cloud infrastructure, and a dashboard to visualize insights.

2) A unique mobile SDK that analyzes device features to detect modifications.

With no one-size-fits-all solution, the Anti-Fraud team works with a large set of features. From detecting attempts based on data with static patterns, using proprietary solutions to detect software manipulation, marking network traffic abnormalities, and identifying when to warn or even block requests.
