In computing, a virtual private network (VPN), sometimes abbreviated VPN in Quebec and elsewhere, from the English Virtual Private Network, is a system allowing you to create a direct link between remote computers. This term is used in particular in remote working, as well as for access to cloud computing type structures. VPN connections are not necessarily encrypted. However, if not encrypted, this can allow intermediaries on the network to access the VPN's traffic, which can be problematic if the information passing through it is sensitive. Additionally, DPI techniques allow firewalls to filter VPN traffic if it is not encrypted. A large number of companies offer free VPNs, and there is no doubt that they use the resale of data to third parties to finance their service. When it comes to privacy and security, it's best to go with a paid VPN. Which of course does not prevent you from carefully reading the conditions of use, particularly in terms of data retention.
