Keeping a healthy network is not easy. These days network is central to everything, making it harder to disconnect. This is not just true for computer networks but also for the web based services we use for day-to-day operations.
Some of the factors affecting the network health are related to attack and unintentional errors in operations. Most organizations have multiple interfaces and systems to reach the main network. Not all of these connections are equally secure.
One approach to keep a secure network is to stop using vulnerable connections and systems but the challenge is to identify the vulnerable connections and when it is better to stop using them. If there is no threat of an attack, monitoring other systems that use vulnerable connections can be too exhaustive and time consuming.
Sysadmins can use a reliable TCP proxy to direct traffic to a new server or even to a new domain name. This can replace the existing system with a better one in terms of security.
Here are a few reasons why you should use a TCP Proxy:
It provides better security.
Changing to a different system saves the system from attack.
Improve application performance.
Can easily monitor the network.
Why do we need a TCP Proxy and how to choose the best TCP Proxy?
Choosing the best TCP proxy:
There are many TCP proxies available in the market. You need to find one that is flexible and has a good performance. It has to fulfill the requirements of your organization as well as there is no harm to your existing systems.
A well-known TCP proxy is NGINX server. It is one of the well known TCP proxies for its reliability and flexibility. It is very highly recommended for securing a network and its purpose is to direct traffic to a new server or domain name.
NGINX can be configured with very simple directives and can be used to replace the backend of an existing server. It is built on an open-source technology, meaning that its development is driven by the community. With NGINX you can replace any web server or backend operating system. NGINX supports HTTP, HTTPS and more.
With NGINX we can use directives like the following:
location / {
proxy_pass 
}
Other reasons to choose NGINX:
The community is behind it and you can get help online from its forums and ask help directly from NGINX team itself.
Some real life scenarios where a TCP Proxy can help:

Gnuplot [Win/Mac]
Gnuplot is a free and open source 3D plotting program that has a simple, easy to use, and much richer scripting language than other 3D plotting programs.
Gnuplot graph plotting software can graph plots in 2D, 3D and even a full web page. You can also create a plot from a text file or a script using gnuplot’s scripting language.
Plotting in gnuplot includes simple 2D plots, which are easy to create, plot area graphics, which are advanced plots, which can be rotated in 3D, contour plots, surface plots, 3D scatter plots, 3D contour plots, 3D surface plots and mesh plots.
Plotting with gnuplot also includes parametric plots, which display more options and information than the simple 2D plots. Gnuplot can plot in several different file formats (such as text, JPEG, PDF, XPM, PNG, SVG, CDL, CorelDraw, Ps, Sff, Agfa2net, and more) and it can plot images (including bitmaps) from all common graphics file formats (including PICT, TIFF, GIF, JPEG, PNG, XPM, EPS, TTF, FON, and more).
gnuplot is also enhanced with LaTeX externalization and embedding, making it a great tool for scientific documents.
