What Is a Proxy Server?



Every device on a computer network has an internet protocol (IP) address that specifically identifies the device. Similarly, the proxy server is a networked computer with a unique IP address. This allows the proxy server to serve as a bridge between users and the internet. Essentially, it is a server acting as a middleman between visitors and the websites they visit. Depending on the use case, demands, or company policy, proxy servers offer varying degrees of functionality, security, and privacy.

The history of networking and the internet itself, dating back to the 1970s, is probably where the history of proxy servers begins. The first proxy servers provided a functional and secure separation layer between local-area networks (LAN) and external networks. Early proxies allowed the shared use of single connections between various computing units by establishing a physical connection between the client application and the computer, where they received and transmitted commands.

Over the years, developers continued to produce increasingly promising proxy technologies. This has resulted in advanced proxy servers that can support customization, extension, and simple deployment. Users can even find programmable proxies in the market that can perform high-end networking functions.

Why are proxies necessary?
Cybersecurity is one of the key reasons to use proxy servers today. They shield endpoints from threats like malware by enforcing web filters or firewalls that can be configured. When someone uses a proxy server, all internet traffic going to the IP they requested passes through the proxy server. The request is then redirected through the same proxy server, and the proxy server sends the information from the website to users. This prevents fraudsters from intercepting your traffic or monitoring online transactions without authorization.

This added security is also beneficial when used with a secure web gateway or other email security tools. You can factor in the amount of traffic that a network or specific computers can handle, its level of safety, or both when filtering traffic in this way.
