What is a Virtual Private Network?

• A virtual private network, or VPN, is an encrypted connection over the Internet from a device to a network. 
• The encrypted connection helps ensure that sensitive data is safely transmitted. 
• It prevents unauthorized people from eavesdropping on the traffic and allows the user to conduct work remotely.  
• VPN technology is widely used in corporate environments.

How does VPN work?

• Data traffic on the virtual network is sent securely by establishing an encrypted connection across the Internet known as a tunnel. 
• VPN traffic from a device such as a computer, tablet, or smartphone is encrypted as it travels through this tunnel. 
• Because the traffic is encrypted between the device and the network, traffic remains private as it travels.

• When the VPN server does this, our IP address, which is the online equivalent of a user-specific postal code, is changed — and thus websites are unable to accurately track our location.
• This private network enhances overall privacy on the Web. It is also used to get around geo-restrictions and online censorship.
