A VPN protects your personal information with Encryption

Encryption is the application of an algorithm for a data block that makes intelligible to an unauthorized person. The most frequently used Web encryption is typed https protocol or HTTPS. HTTPS is encrypted HTTP Web traffic using secure protocols such as the Transportation Security Layer (TLS) or Secure Sockets Layer (SSL). As they are functionally identical, gurus lump together as safe "SSL / TLS."

How HTTPS works is that it establishes an encrypted connection between the Web browser you are using and the server that you have access. Data is encrypted before it is sent to the server on the Internet and only decrypted once it reaches the server safely. The same happens when information is sent from the server to your browser.

SLS and TLS encryption are good and more and more common, however, they can not protect the connection between your computer and a website. Many sites are also still using unencrypted HTTP. Using a virtual private network (VPN) protects all your traffic at a time.

A VPN service provides complete protection for your computer authenticates to a VPN server, making all traffic between your computer and the server encrypted. You can think of a VPN as a secure tunnel between your data from the rest of the data on the network, encrypting all your traffic instead of just part of it.
