A proxy server is a computer or application that acts as an intermediary between a user’s device and the internet. It serves as a gateway, allowing users to access online content and services while masking their true IP address and location. This not only provides a layer of privacy and security, but also allows for faster and more efficient browsing by caching frequently accessed web pages. Proxy servers are commonly used in corporate networks, schools, and other organizations to regulate and monitor internet usage, as well as by individuals to bypass geo-restrictions and access blocked websites.
