What Is a Proxy Detection?
Proxy detection or proxy checkers are used to identify whether a user is hiding their real IP address by using a proxy server instead of a direct internet connection. Proxy detection helps reveal users who are working behind anonymous networks, which allows businesses to maintain clean and reliable data. In this article, you will learn what anonymous proxy detection is, how it works, and why it is needed.

If you are running ads or handling online traffic, using a proxy fraud detection system is very important to keep your data clean and reliable.
