The internet brings concerns like security and privacy with it, especially since it can connect us to different parts of the world.

To make surfing the web safer, proxy servers are utilized not just by individuals but also by companies. It also has some other added functionalities like balancing your server’s traffic and increasing internet speeds. You can even use it to control the internet usage of your employees.

With so many proxies to choose from, it can be hard to find out which is best suited for you. In this article, you will discover what proxies are and what are its main types.

What is a proxy?

The proxy server’s main task is to protect clients from the internet resources, all while directing it to them. The process is straightforward — the client, or in most cases, the browser, will send the information to the proxy. The proxy will then send a request to a server. When the server sees the proxy’s request, it will answer the proxy in the same way will answer a client because it sees it as a connection. As soon as the proxy receives any response from the server, it sends it back to the client. 

One of the most popular proxy types is an HTTP proxy. As mentioned in the example, an HTTP proxy is made explicitly for HTTP connections.

Proxies can be your shield to protect you from other networks by hiding your original IP address when you access data from the server. You can also use it to keep track of leaked data or even increase your own website’s rank.

Main proxy types

Reverse proxy

For reverse proxies, it acts as the main connector between the server and the users. It will serve as the primary endpoint when it receives requests, even if it still needs a server. It will also handle other functions such as routing traffic and even policy management.

Forward proxy

For this type of proxy, the proxy is used to acquire the internal network’s data from its broad group of users. Once the client requests the internal network server, the proxy ‘forwards’ it to the internet, examining the data if it should proceed to make the connection.

Shared proxy

A shared proxy will handle many different requests from different users. Because of how many requests it handles, its setup and configuration may be more complicated than the others.

Rotating proxy

A new IP address will be created for a rotating proxy every time a client makes a request.

SOCKS5 proxy

A SOCKS5 proxy is used for intensive tasks, such as content or video streaming, VoIP and video calls, file uploading and downloading. You can read more about SOCKS5 proxy here.

Datacenter proxy

Datacenter proxies are like cloud-based proxies. The computer’s IP address is generated and isn’t attached to your computer or any other device.

Residential proxy

Residential proxies carry real IP addresses that come from Internet Service Providers (ISPs). They are hardly unblockable and considered one of the most suitable proxies for web scraping.

What makes each proxy different?

Reverse proxy

A reverse proxy can lower the network’s traffic and be used to monitor the clients when they access data. It also adds more security by hiding the IP address of the server you’re trying to reach.

Rotating proxy

Whenever a client requests, a new IP address is created, giving the client total anonymity. You can combine it with other types to increase security.

Datacenter proxy

Because it isn’t attached to any device, it provides one of the best security and privacy for users. Since it is cloud-based, it’s also one of the fastest.

Anonymous proxy

To avoid targeted ads, Anonymous proxies are your most straightforward solution. It doesn’t give your IP address to the server, but it can still be identified as a proxy. However, there is still a chance that your information will be leaked.

Transparent proxy

Most commonly used in schools and companies because of its straightforwardness and simplicity. It’s great for filtering websites but doesn’t offer privacy.
