Endpoint Secure Connection

Why use a VPN?

VPN stands for Virtual Private Network. It establishes a tunnel within a so-called “insecure” network such as the internet.

What is a VPN?

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
