A proxy server is a gateway between your device and the entire Internet. It provides an additional layer of security by filtering the information you receive from the web and preventing your data from being accessed by the websites you visit. Proxy servers allow you to use different IP addresses, making it impossible to detect you as a user. Thus, any website you visit cannot see your actual IP address but rather the IP address provided by the proxy server. Herewith, the proxy IP addresses constantly change.
