What is TLS?

TLS (short for Transportation Layer Security) is a cryptographic protocol used to establish a secure communications channel between two systems. It is used to authenticate one or both systems, and protect the confidentiality and integrity of information that passes between systems.

Here are the browsers that do not support TLS 1.2:
