VPN for Dummies: What It Is and How to Use it to Ensure Your Security

See which service is best suited to keep information traffic on a private network away from interceptions.

A VPN (Virtual Private Network), as the name implies, is a technology used to connect one or more computers to a private network, such as a home or business using an internet connection.

It is a way to keep information transmitted over the Internet more secure, as it works as a layer of encryption and authentication that protects network traffic. It creates a tunnel or communication channel through which the data passes encapsulated, being kept safe until it reaches its destination ADVERTISING

It can be used to protect access to a work network while traveling and to defend browsing data when using a public Wi-Fi network. Using a VPN is the best way to ensure that information can be shared securely.

These networks restrict access to unauthorized persons. In this way, they avoid man-in-the-middle attacks, that is, they prevent the interception of information by cybercriminals who imitate healthy connections by impersonating institutions or companies to steal data.

Currently, there are several VPN services that can be used to achieve the goal of ensuring data privacy. You can even choose from free alternatives. Below, I will mention some that can be a good start for those who want to protect themselves but are not yet familiar with this technology:

Proton Mail

Developed by enthusiasts at the European Organization for Nuclear Research (CERN), Proton Mail is a free encrypted email service, which uses Proton VPN to keep no logs of users’ browsing or their sessions, except for the session active. Its free version only allows you to browse outgoing servers in the United States, which makes the user subject to that country’s privacy laws.


Canadian in origin, Windscribe offers a VPN service with a free version. This plan, while limited to 10GB of data per month, is an option for those who use the service occasionally.

The service can be used by Windows, Mac, iOS, Android, and even an exclusive extension to use in the Chrome browser. It is interesting for travel since the user can choose between 11 servers distributed in several countries in North America, Europe, and Asia, with good results in terms of speed and connectivity.

Regarding privacy, their policy is quite robust and easy to read.

Tunnel Bear VPN

Launched by TunnelBear Inc., this app has a user-friendly interface and is easy to use. It is one of the few services of this type that offers output through servers in Mexico and Brazil, which considerably improves browsing speed for users in Latin America.

TunnelBear is cross-platform and has versions for Windows, Mac, Android, and iOS.
In its privacy policy, the company guarantees that it does not save its users’ browsing data, but the application requests the registration of an email to start using it.
Its free version does not show ads to the user, but on the other hand, it only allows 500 MB of traffic per month.

How to Choose

As there are several VPN service alternatives, the user must bear in mind that the main objective of these apps is to protect their information and privacy. To do this, read reviews of different services on specialized websites, check surveys by reliable companies and carefully study the privacy policies of the chosen VPN networks, trying to choose the one that seems most suitable for your needs.

Here I suggested some options for free apps, but I recommend that if you have the possibility to invest some money, choose the full versions, as your privacy is worth the investment.
By combining this measure of protection with a malware solution, a properly configured firewall, and responsible behavior, a high level of personal information security can be maintained.
