A proxy or a proxy server is a server that acts as an intermediary or gateway between the client and the web server where the client’s information is obtained. Proxies are useful for businesses that want to boost their security and network. Companies that want to retrieve useful information from restricted websites also find them powerful. This is because proxies can make the internet activity seem like it’s coming from a different location.

How Does a Proxy Work?
When it comes to its setup, a proxy can be physically located anywhere, like on the cloud or a computer. When a client makes a request, the proxy will intercept your request. It evaluates and simplifies the request before connecting the client to the source. The proxy server then returns the response and makes it appear as if it originated from the original server. Hence, when your business accesses the internet and makes a request, the client and the source will not know the origin or the final destination of the content.
One way that proxies ensure anonymity is by rewriting the request headers before sending the message to the web server that you are trying to retrieve information from. The server will then think that your request is from a different location, so it will release the response and the proxy will send it to you via your computer.
In most cases, a proxy server is used for security purposes in any business. It helps safeguard data from the increasing activity of web hacking. Proxies will prevent hackers from stealing data from your business servers and also protect them from potential external malware threats.
Proxies for businesses also help speed up the performance, reduce web traffic, and control data flow and web access.
Main Proxy Types
Proxies are categorized into different types which are as follows:
Residential proxies are the most suitable proxy choice for businesses. This is because they use the real IP addresses of real computers and are nearly impossible to detect. Basically, these proxies appear as regular clients to the servers.
Because of their undetectability, residential proxies can help you retrieve useful data for your business with ease. This type is also useful when you want to bypass geographical restrictions.
Unlike residential proxies that use real IP, datacenter proxies use IP addresses that are computer-generated. In this case, the addresses are not linked to a real device but only mimic a real internet connection. The advantage of datacenter proxies is that they are incredibly fast.
As the name suggests, shared proxies are those that can be used by several clients at any given time. They are the cheapest proxy options available on the market since various clients will split the cost. This is especially a good choice for businesses that are just starting out and don’t want to make a huge investment in proxies.
However, since shared proxies can be accessed by many end-users, they tend to have a poor performance than other proxies. This means a powerful network architecture that can handle several connection requests at the same time is necessary.
Another disadvantage is that they are more prone to potential risks.
4. Private Proxy
A private proxy is designed to be used by one person at any given time. This proxy type requires authentication, and only clients with authorization can use it. However, some proxy providers use the word private proxies interchangeably with dedicated proxies.
Despite the ambiguity around private proxies, they can be simply identified as proxies that allow single-client use at the same time.
5. HTTP Proxy
An HTTP proxy is a protocol that sends and displays files on the internet, making it great for web browsing. This proxy is considered a top-notch content filter that identifies suspicious content to protect your web server from attacks.
It serves as a buffer between the web server and the web client to identify suspicious data packets and prevent potential attacks. This makes it a great proxy for the security of your business content.
The SOCKS5 proxy is a type of internet protocol that channels data packets between a client and a server through a proxy server. This proxy is an updated type of SOCKS protocol that provides three types of authentication methods.
This protocol uses proxy servers to create User Datagram Protocol (UDP) or Transmission Control Protocol (TCP) connections via an arbitrary IP Address. It requires authentication via login information and password without sending information about your real address. The SOCKS5 proxy is also flexible and supports multiple programs and protocols than traditional proxies.
If you’re a startup in the online business industry, you should always keep in mind that proxies will provide you with an extra layer of security for your business. We mentioned the various proxy types available for you. All you need is to decide which type would work best with your business.
