Proxy: Definition, How it Works, Benefits and Types of Proxies 2021

Currently, accessing the internet freely is inevitably accompanied by various dangers inherent in data security breaches and identity theft.

So what really happens when you surf the web?

Maybe you use a proxy server in your office by utilizing a Virtual Private Network (VPN) or even, you are using a proxy server for personal use.

No need to worry, in this article you will find out what a proxy is, how it works, and the types of proxies. Listen, yes!

What is a Proxy Server?

proxy server is a system that works as a network intermediary, for example when you access a website page, the proxy will make requests and receive information from the website to the device you are using.

There are different levels of security, confidentiality of information, and proxy functionality according to the type you are using.

Depending on the type, proxy servers work by connecting or even blocking the connection between the sender and receiver of data.

All data entering through one port will be forwarded throughout the network through other ports.

If a proxy server blocks direct access between two networks, then hackers will have a harder time getting internal addresses and private network details.

Some proxy servers can be a group of applications or servers that block public internet services. For example, an HTTP proxy cuts web access while an SMTP proxy cuts access to email.

Proxy servers use a network addressing scheme to present one organization’s IP address to the internet.

After that, all user requests are sent to the internet and the response is returned to the user.

Apart from limiting access from outside, this mechanism can prevent users from reaching certain websites. Not only that, but a proxy server can also be used as a component of a firewall and to cache web pages.

So, every time a user accesses a URL, a temporary copy will be stored locally so that the proxy website can be accessed more quickly the next time it opens.

How Do Proxies Work?

Every computer using the internet needs an IP address. Like home addresses, IP addresses can help proxies know where data will be sent.

When you make a  request or request in the form of a search on Google or accessing a website, the proxy server will send this request to the website server, retrieve the response from the website server, and send it to your browser display.

When the proxy server forwards your request, the proxy can change your IP address so that the website server does not know exactly where you are accessing data.

As a result, your data can be encrypted and unreadable while in transit. Finally, a proxy server can block access to certain web pages based on IP addresses, such as access to websites that are prohibited by the government.

Benefits of Using a Proxy

There are several reasons why many individuals and organizations maximize the benefits of proxies, namely:

  • Control employee’s and children’s internet usage.
    There are a handful of organizations or companies that prohibit their employees from opening several websites for specific purposes. In addition, parents also often use proxies to monitor their minors’ internet activities.
  • Save bandwidth and increase speed.
    One of the benefits of proxies their ability to store  So, when you want to access data from websites that have been visited before, the proxy only needs to access from storage so that it can increase website speed.
  • Privacy is maintained.
    Individuals and organizations that use proxies are usually better able to keep their personal data confidential. This is because proxies can change your IP address and other personal information so that the website server can not access user data.
  • Better security.
    Apart from data confidentiality, you can also take advantage of proxy settings to increase security, for example keeping transaction data confidential or preventing access to malware sites.

Not only that, but organizations can also combine their proxy servers with a Virtual Private Network (VPN) so that remote users always access the internet through an office proxy.

  • Access to blocked resources.
    Proxy servers allow users to access blocked content, for example, access to other countries’ websites. A proxy server can make it appear as if you are accessing websites from other parts of the world, even though you are actually in any place.

Several governments around the world monitor and restrict access to the internet and proxy servers offer their users uncensored access to the internet.

Risks of Using a Proxy

While proxies offer various advantages, there are some proxy risks that you should be aware of.

  • Not all free proxy services are safe.
    Even though it’s free, not all proxy services are safe. Most free proxy services don’t have encryption or a secure hardware backend.  Performance may not be as good as paid services and free proxy services without encryption may have security issues. If you come across a proxy service that’s completely free, remember to be careful.
  • Log search history ( browsing history).
    The proxy you are using may have your real IP address and request information. Try checking, whether the proxy server you are using saves your browsing history, and don’t forget to keep checking the terms and conditions and data security, don’t let your data be sold to third parties.
  • There are proxies that are not encrypted.
    If the proxy server is unencrypted, it means you sent the request in plain text. Everyone can easily access your usernamepassword, location, and even your account information. So make sure that the proxy service you are using is encrypted.

Types of Proxy Server

Types of proxy server

In order not to choose the wrong proxy server, you must know what the following types of proxies are:

Transparent proxy

This type of proxy will tell a website that it is a proxy server and send your IP address so that your access request will be processed. Businesses, public libraries, and schools often use transparent proxies to filter content because it is easier to prepare data from the client and server sides.

Anonymous proxies

Anonymous proxies will identify themselves as proxies, but will not forward your IP address to websites. This can help you keep your data safe and confidential. For example, when knows you are in any Place, they will display news that they think is relevant to that Place. However, this can be minimized if you use an anonymous proxy.

Distorting proxy

distorting proxy can fake an IP address while identifying itself as a proxy. It functions much like an anonymous proxy, but by sending a fake IP address, you can change your access location to a different one from your original location so that you can access blocked content.

High anonymity proxies

High anonymity proxies periodically change the IP addresses they give to web servers making it very difficult to track what traffic is being done by whom. This type of proxy is one of the most anonymous and secure proxies for accessing almost any content on the internet.


In addition to the risks that may be faced, you can also find the meaning, way of working, benefits, and types of proxies from this article.

Don’t forget to pay attention to your safety when surfing the internet, OK! Use the proxy server as necessary for the function.

Don’t let it, you are the one who is irresponsible.

One of the advantages of proxies is their ability to cache. However, to keep your website fast when accessed, you also need to optimize your website.

The trick is to use the best in class cheap hosting and don’t forget to re-optimize to speed up the website.
