What is "vpn"

Virtual Private Network is a private communications network normally used by an undertaking or a group of undertakings and/or institutions, built on top of a public communications network (such as the Internet). Data traffic is carried over the public network using standard protocols, not necessarily secure.

A VPN is an established connection over a public or shared infrastructure, using tunneling and encryption technologies to keep data traffic safe. Secure Vpns use tunneling encryption protocols that provide the confidentiality, authentication, and integrity necessary to ensure the privacy of the required communications. When properly implemented, these protocols can ensure secure communications across insecure networks.

It should be noted that the choice, implementation and use of these protocols is not something trivial, and several unsafe VPN solutions are distributed in the market. Users are warned to investigate carefully the products that provide Vpns.
