VPN clients the preferred solution may be to open an account with a vpn services rather than simply purchase or acquire of-the-shelf vpn software so that they benefit from the extra services that many vpn providers will supply their clients with. As vpn services therefore have to transmit private information across unsecured networks such as the world wide web, they need to ensure that the data exchanged across these networks is kept secure by employing a combination of encryption on the data packets and authentication to allow access to only those users with permission. Authentication is the process that determines whether attempted access to a network should be given or not. Data is scrambled so that it cannot be interpreted when travelling across networks. This is called encryption and is vital for data being able to travel securely. It means that the data packets are ineligible to humans. In the real world a tunnel is a passageway, and in the virtual world it is similar but instead of somewhere for cars or people to travel it is where data travels. With vpn, a tunnel is a passageway through a network where data packets travel. It is secure meaning traffic can move safely where is might not be possible without the tunnel.
