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 with modern cloud infrastructure that provides different interfaces to partners.
2) A unique mobile SDK that analyzes device features to detect modifications via xposed or magisk.
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.
Join a team that is excited about the latest technologies and is highly interested in data, security, cloud computing, and mobile operating systems. Not to mention a team that celebrates many awards for leading the way in fraud prevention.
