Source: Windows Central On computing, a proxy server sits between a device and the internet to retrieve web data on behalf of the user. Usually, there are three reasons to use a proxy, including privacy, speed, and traffic monitoring. Privacy is perhaps the most important benefit because it allows you to navigate the internet anonymously since the computer will be requesting information to the proxy (not to the website directly). Then the server will retrieve the information for the client, hiding your public network address. A proxy server can also improve internet speeds and reduce bandwidth. For example, if the organization has a proxy in the network, whenever a request is made, the server will also cache the web page in its database, and it will serve it to other users if they request the same information. Also, organizations may use this solution to monitor the websites users access and create an access list to block specific sites.
