In other words, a VPN extends a private network across a public network and enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network. It secures the users' connection over the internet.

If any hacker tries to hack the IP address and gets successful, then all the information the user has on the web can be leaked or used in the wrong way. VPN can give security to the online profile of the user. VPNs use protocol systems. These protocol systems encrypt the user's data. Some VPNs provide twice encryption system. The encryption protocol makes it unreadable or inaccessible to the hackers.
