Why use a VPN?
VPN stands for Virtual Private Network. It establishes a tunnel within a so-called “insecure” network such as the internet.
To ensure that data exchanges are secure, a VPN performs three functions:
- Authentication using a key to make sure that the devices are authorized to communicate with each other
- Data encryption to guarantee the confidentiality of exchanges
- Data integrity to ensure that data has not been tampered with
