A proxy server is a system or router that provides a gateway between users and the internet. It is often referred to as an “intermediary” because it goes between end-users and the web pages they visit online. When a computer connects to the internet, it uses an IP address, similar to your home’s street address. This address tells incoming data where to go and marks outgoing data with a return address for other devices to authenticate.

One of the primary roles of a proxy server is to enhance network security. It helps prevent cyber attackers from entering a private network2. Proxy servers provide a valuable layer of security for your computer. They can be set up as web filters or firewalls, protecting your computer from internet threats like malware. This extra security is also valuable when coupled with a secure web gateway or other email security products.

Proxy servers also play a crucial role in improving network performance. They can control the websites employees and staff access in the office, balance internet traffic to prevent crashes, and save bandwidth by caching files or compressing incoming traffic.

In terms of privacy, proxy servers act as a shield, masking the true origin of the request to the resource server. Some people use proxies for personal purposes, such as hiding their location while watching movies online.

There are different types of proxy servers, each serving a unique purpose. A forward proxy is an Internet-facing proxy used to retrieve data from a wide range of sources. A reverse proxy is usually an internal-facing proxy used as a front-end to control and protect access to a server on a private network.

An open proxy is a forwarding proxy server that is accessible by any Internet user. Anonymous proxies reveal their identity as a proxy server but do not disclose the originating IP address of the client1. Transparent proxies not only identify themselves as a proxy server, but with the support of HTTP header fields such as X-Forwarded-For, the originating IP address can be retrieved as well.

In conclusion, proxy servers are an integral part of modern computer networking. They provide a balance of security, privacy, and performance, making them an essential tool in today’s digital landscape. Whether you’re an individual seeking to protect your online privacy or a business looking to secure your network, understanding and utilizing proxy servers can offer numerous benefits.
