A virtual private network (VPN) is a technology that creates a safe and encrypted connection over a less secure network, such as the Internet. VPN technology was developed as a way to allow remote users and branch offices to securely access corporate applications and other resources. To ensure safety, data travels through secure tunnels and VPN users must use authentication methods — including passwords, tokens and other unique identification methods — to gain access to the VPN.
Without VPN anyone with the technical expertise is able to view and misuse information contained in your normal Internet traffic.
Because I feel my Internet sessions are of no concern to anyone (especially the government and including law enforcement) I use VPN to encrypt and secure my Internet sessions.
