Virtual Private Networks, or VPNs, are an extremely important tool for your online life. VPN use, at its most basic level, entails creating a tunnel through which your encrypted data passes, making you more secure and anonymous online. 

Below we will have a closer look at what VPN is: 

Defining VPN 

Let’s get back to basics. The term VPN refers to a virtual private network. Using a virtual private network (VPN) is a simple and effective solution to improve your online security, privacy, and independence. 

When you use the internet, your device is constantly sharing data with other parties on the internet. A VPN establishes a secure connection between your device and the internet (for example, a smartphone or laptop). The VPN allows you to communicate data to an external server via an encrypted, secure connection: the VPN server. Your data will then be forwarded to its final destination on the internet. 

There are various benefits to rerouting your internet traffic through a VPN server. It first aids in the concealment of your online identity. Second, it safeguards your information. Finally, it gives you more freedom when using the internet. 


How does it work? 

Connecting to a VPN is usually an easy process. You download and install VPN software after subscribing to a VPN service. You simply choose a server to connect to, and the VPN takes care of the rest. 

Once you are connected, the following will happen to your data: 

  • Your data traffic is encrypted and sent to the VPN server over a secure connection via the VPN software on your computer. Your Internet Service Provider receives the data as well, but due to encryption, they are unable to eavesdrop on it. 
  • The VPN server decrypts the encrypted data from your PC. 
  • Your data will be sent to the VPN server across the internet, and you will receive a response that is intended for you, the user. 
  • The VPN server encrypts the traffic again before sending it back to you. 
  • The data will be decrypted by the VPN software on your device, allowing you to understand and use it. 
  • Your computer, tablet, or smartphone’s VPN application operates in the background. You’ll be able to use the internet as usual and won’t notice any differences – except that you’ll be able to circumvent online limitations. 

Is a VPN safe to use? 

You might be concerned about your safety when using a VPN service. Your internet traffic is rerouted and directed through the VPN provider’s servers. If the supplier so desires, it can monitor everything you do. As a result, it’s critical that you have faith in your VPN provider. Most VPN providers do not keep track of what you do or store your information. 

A final thought 

Users on the internet have begun to realise that VPNs are used for more than just security. It’s no surprise that there’s now an International VPN Day! They’ve evolved into a terrific tool for TV streamers, torrenters, travellers, shoppers, and a whole host of other people.
