What is VPN (Virtual Private Network)?

Surfing the web or transacting on an unsecured WiFi network means exposing private information and browsing habits. Although it sounds so dangerous to think about, VPN ( Virtual Private Network ) provides you a protected network connection while using public networks. It encrypts your internet traffic and hides your online identity. In such a situation, it will be difficult for third parties to track your online activities and steal your data.

VPN connects your PC, smartphone to the server computer, and you can browse the internet using that computer’s internet connection. VPNs are legal and are used by individuals and companies worldwide to protect your data from hackers. It is also used in countries where there is a highly restrictive government. After knowing so much about VPN, it must have been understood that it can be used for its online security on a public network, but how does this VPN work?

How Does VPN Works?

So your internet traffic passes through an encrypted tunnel that no one can see. That is, neither hackers nor the government nor your internet service provider, i.e., your data cannot be read. Let us look at two situations to understand how a VPN works, first without VPN and second with VPN.

  • Without: When we access the website without a VPN, that internet service provider can connect to the site through the ISP. ISP gives us a unique IP address but because ISP directs and handles all our traffic. He can trace the websites we visit. So, where is our privacy secured? Let’s talk with VPN.
  • With: When we connect to the Internet with a VPN, the Virtual Private Network app on our device is also called a VPN client, and it establishes a secure connection to the VPN server. Our traffic still passes through the ISP, but the ISP cannot see the final destination of this traffic, and the websites we visit cannot see our original IP address. Well, why was a VPN needed?

Why do we need a VPN, and When?

It was first developed by Microsoft in 1996 so that remote employees, i.e., employees who do not work sitting in that office but work from anywhere while living outside it, can get secure access to the company’s internet network. But by doing so, the company’s productivity doubled, so other companies also started adopting VPN.

So when should we use VPN? The next question and the answer to this are that if privacy is very important for you, then you must use it every time you connect to the Internet. But still, there are some situations in which you must definitely use a Virtual Private Network, such as while streaming, traveling, using public Wi-Fi, playing games, and shopping. It was interesting to know how it works and when to use it. But now we know further whether there are different types of VPN as well.

Do VPNs are of Different Types?

Yes, there are two basic types of VPN; Remote Access and Side to Side.

  • Remote Access: The remote access medium allows users to connect to other networks through a private encryption tunnel. Through this, it can be connected to the company’s Internet servers or the public Internet.
  • Site-To-Site: Site-to-Site is also called Router to Router VPN. This type is mostly used in corporate environments, especially when an enterprise has its headquarters at several different locations. In such a situation, a site-to-site VPN creates such a closed internal network where all the locations can be connected simultaneously. This is called intranet.

If you look at the benefits of VPN together, it hides your browsing history, IP address, streaming location, devices, and web activity. But it also has some disadvantages along with benefits such as comparatively slow speed, no cookies protection, and not total privacy.
