Explaining how commercial Virtual Private Networks really work

Most people, who decide to take care of the security of their personal information and surfing the Internet, choose the services of a Virtual Private Network (VPN). Their choice is determined not only by the VPN's high popularity, good reviews, but also by security that is guaranteed. In this day and age, when thousands of hacker attacks happen every day, targeting both individuals and businesses, you don't want to find out that your chosen security measure was not reliable after seeing an empty bank account, right?

However, the question is how does a VPN work? Why does this tool provide exceptional security for internet users? And is it really secure?

How does a VPN work?

Although the question seems quite complicated, in fact, the operating principle of VPN is quite simple. After you find out which commercial Virtual Private Network suits your needs the best and subscribe to it, all you have to do – to select a server you want.

Depending on the VPN service provider, it may offer a different number of servers in different countries. Depending on the content of the website you want to access, you need to choose a server from the appropriate region. When you connect to the desired server, you can be sure that the VPN service provider will do everything to prevent your information from being accessible to third parties. Let's look at the process in more detail:

  • First of all, VPN encrypts your data traffic and it is sent to the server securely. Therefore, all your information that you send and receive is as if in a tunnel. Although usually the information of Internet users can be viewed by website administrators, Internet providers or representatives of certain state institutions, in this case, this information is inaccessible even to them.
  • The information from your device is decrypted by the server. In other words, the information is being made readable again but can only be accessed by the server. It is important to note that this does not make it available to third parties.
  • After that, when the VPN server sends information back to you, the traffic is being encrypted once again. Thus, this way leaves no loopholes that would allow hackers to gain access to you or any of your information.
  • When the information from the server reaches you, it is decrypted instantly. Therefore, you can see it without any problems.

Although this path of information from the Internet user to the server and back seems rather confusing, it is not. Everything happens almost instantaneously, so Internet users often have no idea what processes take place when they connect to a VPN. They just use the Internet as they are used to. Meanwhile, a VPN invisibly makes sure that your internet browsing is safe.

However, it is important to note that the information you disclose online cannot be protected. Therefore, do not lose your vigilance and think carefully whether it is necessary to disclose your personal data in each case. Often, believe it or not, even the smallest detail can help hackers to trace you back.

Main advantages of encrypted data traffic

Although the main reason people choose VPN services is data security, data traffic encryption also has other benefits. Have a look at the main of these!

  • You may avoid geo-restrictions and access the content you want. Therefore, by using VPN services, you can forget about those times when you cannot access the movie, music or game site you want. Any content is available in just a few clicks.
  • People often ask - Can a VPN reduce ping? And the good news is that it really can! You may notice it when playing online games because a VPN you use usually takes a route to the server which is more direct than the one that your Internet service provider offers.
  • Finally, you may enjoy taking advantage of the best prices! With a VPN, you can access the best deals for residents of other countries. In this way, you can buy a Netflix, Spotify subscription cheaper, book flights and hotels cheaper. Also, to save a significant amount of money when buying clothes, video games or other things.
