What is a VPN? – Introduction and Advantages


What is a VPN, and what is it for? Its acronym means Virtual Private Network or Virtual Private Network in our language. It is an online service that can hide your real IP address and allows you to access restricted or blocked content based on your geographical position or by the operator, even for pages that are not entirely legal or to access downloads. For example, P2P. It also allows you to protect your data when you browse the Internet, thanks to traffic encryption. They may be the best solution if you are connected to a public Internet connection.

This service uses a server and a client. First, you install your client on your device, mobile, or computer, which is use to connect to this server. Next, a private channel or tunnel is created, a local network between your client and the server without the need to be physically connected. Once this network is created, all information that travels through it is encrypted and protected to improve security and maintain anonymity.

Advantages of VPN

Using this has all kinds of advantages, but the main one is to keep you private when you browse the Internet and protect your activities. You can access restricted content from anywhere. Some of the advantages of using a free private network are:

Hide Your IP

Unlock Pages

You can bypass filters or access sites that may be block if you don’t have one of these options installed. So, for example, you can avoid the possible firewalls if you are in areas with restrictions, such as China, for example, a country where the government censors some pages.

Greater Security

All documents and files are protect or encrypted when you connect to the Internet using any VPN service. It is essential when connecting to a public WiFi network since it will cover all the data or information you are using from that connection. Thus, you will prevent some cybercriminals from getting your information and using it with the damage that it would cause you.

Fast Connection

You can quickly connect or disconnect with a single button to use only when you need it and not always. Thus, only you decide how and when without any obligation or unnecessary payment.

Is VPNs Legal?

The answer is yes; all VPNs (regardless of whether they are free or premium) are perfectly legal in most countries, including Spain. However, some exceptions exist in countries with little freedom, such as Iran, North Korea, Indonesia, Russia, and China, among others. These countries have restricted VPN use because they do not want their citizens to access certain prohibited websites. Such as Facebook, Twitter, or Netflix. Therefore, if you are caught using this network technology in any of these places, you will most likely face a significant financial penalty or even jail time.


A virtual private network extends a private network across a public network. It enables users to send and receive data across shared or public networks as if their computing devices were directly connect to the private network.
