How Does a VPN Work?
Essentially, a VPN creates a data tunnel between your local network and an exit point at a different location that could be thousands of miles away.
It redirects internet traffics, hides your IP address and encrypts all the data sent or received. With advanced encryption techniques, VPNs scramble data and make the data unreadable. In this sense, a VPN prevents anyone else on the network from eavesdropping on your internet activity.
