In order to function properly, VPN software needs to rely on a mechanism known as "tunneling" in order to give users all the features they expect from our service. Tunneling allows for a lot of things to happen, including increased anonymity, enhanced security, and a broader level of access to all the different types of web content you like to enjoy.
Tunneling works when a VPN sets up a network connection to a server, and sends your data in broken up little pieces (called "packets) through one of a few different VPN protocols. You can read more about the specifics of VPN protocols from our knowledgebase article included here.
Once the data reaches the server it's then reconstructed back together again, and the connection is complete. It's this breaking up and rebuilding of the data between the client and the server that keeps your information protected, because only the two sides of the equation are able to make sense of the noise once it's been decrypted on their end.
