What is Transport Layer Security (TLS)?

Transport Layer Security, or TLS, is a widely adopted security process designed to facilitate privacy and data security for communications over the Internet. A primary use case of TLS is encrypting the communication between web applications and servers, such as web browsers loading a website. TLS can also be used to encrypt other communications such as email, messaging, and voice over IP (VoIP). 

We currently use TLS version 1.2
