Originally VPNs are corporate networks that ensure a safe encrypted connection between employees’ computers and company's server.

- A client connects to a VPN server from his computer then passes identification and authorization.
- The information between remote computers could be swapped securely if computers are interconnected through the VPN server. Transmitted files pass the VPN server before reaching any computer from the network;
- VPN technology routes the traffic over the public channels using the sophisticated encryption.
The conversation occuring today will determine the amount of trust we can place both in the technology that surrounds us and the government that regulates it. Together we can find a better balance, end mass surveillance and remind the government that if it really wants to know how we feel asking is always cheaper than spying.
