A Virtual Private Network (VPN) is a secure way of connecting to a private Local Area Network at a remote location, using the Internet or any unsecure public network to transport the network data packets privately, using encryption. The VPN uses authentication to deny access to unauthorized users, and encryption to prevent unauthorized users from reading the private network packets. The VPN can be used to send any kind of network traffic securely, including voice, video or data.
VPNs are frequently used by remote workers or companies with remote offices to share private data and network resources. VPNs may also allow users to bypass regional internet restrictions such as firewalls, and web filtering, by "tunneling" the network connection to a different region.
Technically, the VPN protocol encapsulates network data transfers using a secure cryptographic method between two or more networked devices which are not on the same private network, to keep the data private as it passes through the connecting nodes of a local or wide area network.
Is VPN legal?
Yes, it is!
There is no doubt about it. VPN services are perfectly legal! It only depends on you how you use them. As long as you are not performing illegal activities, then it is perfectly legal to use a VPN service. Even though you use a VPN for some illegal activity, this does not make the use of such services illegal.
There are a lot of benefits a VPN service offer including:
Hiding your real IP address
Access blocked websites and applications
Surf the web privately and securely
Easy to use, easy to install and configure.
In other countries where the access to certain sites like Facebook, Twitter, MySpace is prohibited, the use of VPN is not illegal. It is restricted, but not illegal.
Also, it is legal to use a VPN to unblock Hulu, BBC iPlayer or other services that are restricted to users from certain countries.
To sum up, you can’t get in any trouble for using a VPN unless you are suspected of doing illegal activities while under hidden IP’s.
