Good to know, VPNs

VPNs can help you get rid of geographical restrictions and  surf the internet securely by allowing you to make it look like you are connecting from a different country and place. They can be beneficial in most scenarios but have you ever wondered how do VPNs work? In this article, we will explain everything you need to know in a very simple way!

How do VPNs work?

Instead of the user's typical internet service provider (ISP), a VPN routes a device's internet connection through a private service. By concealing the user's IP address, the VPN serves as a middleman between them and the internet while they are online.

By using a VPN, a user's device can access the internet while hiding their identity, location, and other data through a private, encrypted tunnel. VPN establishes a secure connection for all network traffic. As a result, any data that is sent over the internet is routed through the VPN rather than the user's PC.

Your data is routed through a server in another nation or region after being encrypted. This way, you can mask your online activity to keep it hidden from prying eyes like hackers, ISPs, governments, or advertisers.

As mentioned in the beginning, You can establish a private and secure connection between your device and the internet using a virtual private network.

What are the use areas of VPNs?

It might be confusing for a tech-savvy to understand how VPNs work, but in the end, the use areas are pretty simple. They are related to our daily lives and help us overcome some of our concerns while surfing on the internet. 

A VPN is a powerful tool that can enhance your online experience in many ways. By using one of the desired VPN services, you can enjoy more security, privacy, anonymity, and freedom on the internet.

  • Hide your IP and location: By giving you a new IP address based on the server you select, a VPN hides your real IP address and location. This makes it more difficult for someone to trace your identity or location online.
  • Avoiding censorship and geo-restrictions: Using a VPN, you can access websites and services that are banned or blocked in your nation or region. For instance, by connecting to a US server, you can watch Netflix programs that are exclusively offered in the US.
  • Improve your security online: A VPN encrypts your data, preventing anyone from intercepting or tampering with it, so enhancing your security and privacy.
