What is a Transparent Proxy: A Simple Guide(2021)


A transparent proxy is a server that intercepts the link between an end-user or computer and the internet, also referred to as an inline proxy, proxy intercepting, or coerced proxy. It is called “transparent” because, without changing questions and replies, it does so. A common open source transparent proxy tool is Squid Transparent Proxy Server.

A person on a business network, for example, could be browsing the Internet. The customer demands a news story on cnn.com to be accessed and displays the same content as they would on their home local page.

In this article let us look at:

  1. Transparent Proxies and Forced Proxies
  2. Transparent Proxy Settings
  3. Uses with Client-Side Open Proxy

1. Transparent Proxies and Forced Proxies

Transparent proxies are often referred to as forced proxies since they can be added to the link of a user without any modification to the proxy settings of their device.

As a consequence, without their permission or understanding, a clear proxy may be “forced” on a person (although in many cases users are informed about the presence of a proxy). To help users become aware that they are being watched, certain websites maintain unauthorized, open proxy lists.

By definition, transparent proxies are set up by the provider of a network or a website, not by the end-user.

2. Transparent Proxy Settings

Any of the popular proxy settings when you’re setting up a clear proxy are:

  • Authentication – Provides the same passwords to the server as users behind the proxy
  • Interception – Defines how the proxy, at the operating system or router level, can intercept traffic.
  • Caching – Defines whether content for returning users should be cached by the proxy server
  • You may put the proxy in front of a web server to speed up user efficiency. Reverse proxy (as opposed to setting it to intercept remote access)
  • Configure the transparent proxy not to allow users to access those protocols or ports by filtering chat, data streaming, torrent threads, etc.

3. Uses with Client-Side Open Proxy

On the client-side, you should deploy a transparent proxy, meaning that the proxy intercepts all traffic to and from a client endpoint. Usage cases with clear proxies on the client-side include:

  • Content filtering: A transparent proxy may be used to screen out undesirable content specified by the proxy settings. For instance, the proxy may refrain from forwarding the request to the web server when a particular website is requested. Rather, it intercepts the link and gives the user an error or note.
  • Gateway Proxies: To change or restrict network traffic depending on rules, you can use a gateway proxy. A firewall, for instance, is a transparent proxy that allows traffic to move between an internal network and the Internet but blocks traffic if it breaks the rule table of the firewall.
  • Transparent caching: Since many entities access the same content from the same location, for example, several students visit the same news source from their university network, it is more effective to cache the content initially and deliver it to subsequent users from the cache. For an entity, facility, or community, a clear proxy may do this.
  • Activity Monitoring: You should set up a clear proxy to track user traffic and actions if you run a network. Traffic management may also have unlawful uses, such as monitoring user connections and stealing data and passwords from an unscrupulous public wifi operator.
  • Authentication: Wireless Internet providers and public wifi spots often use transparent substitutes to compel consumers to authenticate themselves and adhere to the terms of service on the network. They’re only able to surf after a person authenticates and approves. Users may not know that the entire link is intercepted even after the initial authentication screen and may be tracked by the user.


The way we communicate with the network is formed by translucent proxies. If they serve data faster by caching, filtering out inappropriate information, or allowing organizations greater leverage of their networks, without causing annoyance, transparent proxies bring functionality to the Internet.
