What is a Proxy Server?

A proxy server is software or a device that acts as a gateway between a user and the internet. It facilitates requests from client computers to access external resources, such as web pages. In their role of acting as a gateway to the internet, proxy servers evaluate requests, perform caching services, handle the network tasks, and return the requested information to the initiating computer.

Organizations often set up proxy servers for security reasons, since they can act as firewalls and provide an additional layer of security against hackers. They can also set controls on the proxy server to prevent employees from accessing certain types of websites. Individuals can use proxy servers when accessing the internet for personal use, masking their IP address and making it easier to anonymously use the internet.
