VPN | WHAT IS VPN? HOW DOES IT WORK? TYPES AND BENEFITS

Since the advent of the internet, the world has become a global society with almost every individual, Country and establishment having an online presence. This creates the obvious need to protect and encrypt internet data.

VPN stands for virtual private networks. This application gives the user a unique opportunity to establish a secure internet network, especially when using public internet sources.

Virtual private networks achieve the above via real-time automatic encryption of the users’ internet traffic and hiding the user’s online identity.

This grossly limits the ability of third parties and hackers to track or monitor your activities online.

How does a VPN work?

Virtual private networks mimic a private internet source from an apparent public network and give the user the freedom to use data on the public network as if their devices were connected to a private network.

Virtual private networks create a virtual point to point internet connection through the use of dedicated circuits or tunnelling protocols over existing internet sources.

Consequently, all Internet traffic and communication generated by the user is passed through this secure tunnel. The user’s internet protocol (IP) address is also hidden from the public eyes.

The implication of the above is that while using any virtual private network, the virtual private network server becomes the user’s source of data.

This limits the ability of your internet service provider (ISP) and other third parties from getting meaningful information about your activities online.
