What Is a Proxy Server and How Does It Work

data center

A proxy server is a system or router that provides a gateway between users and the internet. Therefore, it helps prevent hackers from starting a cyber attack on a private network. 

It acts as an intermediary between the internet and the computers connecting to it using IP addresses, similar to street addresses that help incoming data find its destination. The proxy server itself can also be accessed via an IP address.

Proxy Servers and Network Security

Proxy servers are popular security systems because they protect data at the network level. This layer of security is more effective than firewalls because of the additional protection. For example, it maintains a list of blocked sites that can be updated in real-time, while firewalls only block traffic once a new entry is added to the blocklist.

In addition, proxy servers prevent malware and viruses from accessing private networks. This is because such a program or website will not access the network’s IP address through a proxy server unless the device has the correct authorization.

A proxy server can also work with a firewall to create a more extensive security system. Without a proxy server, a hacker could gain access to the network by finding a way around the firewall.

Why You Need a Proxy Server

Internet users need proxy servers to access the internet securely via a private network. Proxy servers can also be used to protect local networks from malware and attacks from external sources.

Proxy servers can be cloud-based, shared, network-based, or software-based. Each type has its own features, security systems, and costs. A proxy server can also be used to create a VPN, which is one of the most secure methods of internet access.

Types of Proxy Servers

Proxy servers come in different types. There are public proxy servers that anyone can use, and private proxy servers are only available to those with IP addresses.

Proxy servers, or proxy caches, are also often used to improve website performance. A proxy cache caches objects you visit on the internet for some time, so if you revisit the website, it does not have to go out and fetch that information again. This process is called a web proxy cache and differs from the primary purpose of a proxy server.

Internet uses can also control the data that passes through the proxy server. A proxy server can block dangerous websites, news, and ads. Some proxy servers also block content by country.

Choosing a Proxy Server

Here are some of the critical factors that you need to consider when searching for a secure proxy server:

Performance: If you want to use a proxy server to speed up your internet connection, look for a fast and efficient one.

Security: A proxy server is a gateway to the internet, so it must be secure.

Reliability: A proxy server should be reliable and consistent.


Proxy servers provide security and privacy to internet users and help prevent malware and viruses from entering private networks. But, there are different types of proxy servers. To choose the right one, you need to consider the kind of security you need, how fast the internet connection is, and how much you are willing to spend.
