A little theory

What is a VPN?

A VPN, or virtual private network, creates a private network connection between devices on the Internet. VPNs are used to transmit data securely and anonymously over public networks. Its operations include hiding the user's IP address and encrypting data so that it cannot be read by those who are not authorized to receive it.

What is a VPN for?

VPN services are mainly used to send data securely over the Internet. A VPN has three main functions:

1. Data protection

Without a VPN, your personal data (such as passwords, credit card information, and browsing history) can be accessed and sold to third parties. VPNs use encryption to keep this sensitive information private, especially when connecting to public Wi-Fi.

2. Anonymous

Your IP address contains information about your location and browsing activity. All websites on the Internet use cookies and other similar technologies to track this data. They can recognize you every time you visit them. A VPN connection hides your IP address so you remain anonymous on the Internet.

3. Security

VPNs use encryption technology to protect your Internet connection from unauthorized access. It can also act as a shutdown mechanism, removing pre-selected programs in case of suspicious Internet activity. This reduces the chance of data being compromised. These capabilities allow companies to grant authorized users remote access to corporate networks.
