What’s a VPN and how does it work?
A Virtual Private Network (VPN) encrypts traffic between two end points on the Internet creating a secure tunnel that does not let any external entity to intervene; note that it has nothing to do with providing access to internet.
A VPN guarantees the most extreme level of security to a client/internet-user by steering the greater part of its information movement through a protected tunnel which is for all intents and purposes unbreachable.
Why do you require a VPN?
A Virtual Private Network is currently on of the most preferred tools for staying safe from hackers, government spies, ISPs, identity thieves, DDos attacks, account hacking and much more. Usually good VPNs such as IPVanish and Pure VPN employ 256-bit encryption which is next to impossible to breach. And not just that, VPNs are also useful for unblocking geo-restricted websites and downloading torrents anonymously.
