A virtual private network (VPN) allows users to remotely access a private network and share data securely while using a public network such as the Internet. VPNs are often described as exclusive tunnels that travel through the Internet. The key is that no one can peer into your tunnel and no one else can use it. VPNs are private networks but they are like Wi-Fi networks at home, created by networking protocols to appear and act like a public network. There are three main VPN technologies: trusted, secure, and hybrid.
