Transparent Proxy – Is It Worth A Try?

The Internet is no longer a safe place, and every internet user is trying their best to keep cyber threats under control. A transparent proxy, a viable cyber security tool, is critical from an online data protection point of view.

With a variety of proxy servers, a transparent proxy is many things, and its effective usage is only possible when you’re fully aware of its meaning and capabilities. Let’s know more about transparent proxy.

Transparent Proxy – Having Clarity On Basic

Let’s start with a simple explanation of ‘what is a transparent proxy?’.

Well, it’s a proxy server that sits between the internet user and website servers without being noticed. Unlike a normal proxy server, a transparent proxy remains hidden. The end-user won’t be aware of its presence.

It won’t be erroneous to say that transparent proxies keep end-users in the dark while empowering the administrators.

Other than this, the distinctive traits of transparent proxies are:

  • Different set-up process

Traditional proxies need prior configuration or set-up. And in general, Certain network changes are required to make a customary proxy server work.

The scenario for the transparent proxy is different. In this variety, the proxy directly intercepts the packets that the request destination receives. This sort of request interception won’t ask for any prior set-up and configuration.

  • No request & response modification

Transparent proxies don’t make any changes in the request & response, which is not the case with customary proxies.

  • Same user experience

Traditionally, proxy servers tend to cause a page load speed drop as the request first has to reach the proxy server and then the end user. Gladly, this isn’t the case with transparent proxies, as no traffic filtration happens.

Let’s understand it with the help of an example. Suppose a corporation is using a transparent proxy when an employee tries to access a website, a transparent proxy processes the request in place of the website server.

There is no traffic filtration; hence, there are no response delays.

The Key purpose of Usage

The main goal of transparent proxy implementation is to have an eye on internet usage. Corporates, academia, and other bodies have it to find out what all activities corresponding internet users indulged in. Based on the allowed activities and excess, administrators can easily restrict one’s internet access.

Also, other proxies are often deployed by the end-user himself for cybersecurity purposes. Contrary to this, corporates, network administrators, and website owners deploy transparent proxies.

Transparent Proxies vs Forced Proxies

Many proxy users use the above terms interchangeably, and they are correct. Transparent proxies are often deployed without the end user’s consent and knowledge. So, we can say they are forced on them. To summarize, transparent and forced are two different names for one technology.

The Transparent Examples From the Real World

A squid transparent proxy is a very famous example. This open-source and transparent tool allows network administrators to do effortless network monitoring. It comes with 3 modes of usage, normal forward proxy, reverse proxy, and transparent proxy.

FortiGate is a very high-end online security tool based on transparent proxy-based engines. It helps in SSL session interception and monitoring of the content. It can decrypt the communication for easy inspection and re-encryption.

Pros And Cons Of Transparent Proxy

Using a transparent proxy brings ample benefits, such as:

  • No set-up and configuration hassles. It installs automatically and won’t ask you to follow tedious configuration and network setting optimization.
  • Proper content caching will lead to optimized network performance.
  • Control over internet access as admins can easily block a website or web page.
  • The content caching facility of transparent proxy allows admins to store space configuration by defining the minimum and maximum item size.
  • Complete monitoring of internet activities.

Despite the copious benefits, a transparent proxy isn’t always a great deal. It has certain loopholes like:

  • No IP address concealing
  • No online security as the end-user data remains exposed.
  • Non consensual implementation
  • Risk of data exposure as end-user information isn’t protected.

Use Cases

In most implementation scenarios, transparent proxies exist for:

  • Internet usage monitoring
  • Bandwidth saving with optimized content caching
  • User authentication over WiFi connections
  • DoS protection with the help of TCP interception
  • Front-end optimization with the help of CDN and transparent proxies

Transparent Proxy Settings

The implementation of a transparent proxy demands certain settings. For instance:

  • Server authentication using the end-user credentials
  • Interception to make sure how the proxy should decide the traffic
  • Caching that will help transparent proxy to define which response, reaching to end-user, should be cached and which shouldn’t
  • Reverse proxy setup for improved performance
  • Defining data, torrent threads, and chat filtering protocols so that certain data can be protected.

Concluding Words

A transparent proxy is more like an internet-monitoring tool empowering network admins and website owners so much so that they can keep tabs on the end-user activities. But what about the security and secrecy of the end users?

Sadly, this is not what you could experience with a transparent proxy. It’s great for internet monitoring and access control, but you can’t expect online security. Also, users are often ignorant of its presence.

To summarize, the implementation of a transparent proxy depends on your goals. Have clarity on this aspect and then adopt this technology.

It depends on the purpose for which you want to use this tool. For instance, if you want to use it for online activity monitoring, it’s a great choice to make. But, it’s not worth a bet if you’re expecting great cybersecurity, as it disappoints greatly on this front. There is no IP address concealing and data protection.
