VPN

What does VPN mean?

A Virtual Private Network (VPN) is a secure tunnel between two or more devices over a public network, such as the Internet. It allows users to securely access private networks, such as those at work or school, while they are away from the office or campus. VPNs are also used to protect online privacy and anonymity by encrypting traffic and hiding users’ IP addresses.

VPNs work by creating a secure connection between the user’s Device and a remote server. The traffic between the user’s device and the server is encrypted, making it impossible for third parties to eavesdrop on the connection. The remote server then forwards the traffic to the desired destination.

VPNs are an essential security tool for businesses and individuals alike. They provide a secure way to access private networks and protect online privacy.
