What is a VPN (Virtual Private Network)

A VPN stands for Virtual Private Network and is a means of connecting through a network over a secure encrypted connection to secure all data in transit. When you connect to a VPN you effectively tunnel all your network traffic through another server through a secure connection which then makes requests and or retrieves data on your behalf. 

 VPN applications can help to preserve your privacy by hiding your IP address on the network you are connected to and accessing websites that may be blocked in your country or region. This technology enables data to be transmitted securely over networks with poor security such as wireless networks at hotels, coffee shops, or other public locations by utilizing Cryptography to encrypt all the information in transit before it leaves the device.
