Transport Layer Security (TLS) is a protocol that ensures privacy between communicating applications and their users on the Internet. When a server and client communicate, TLS ensures that no third party may eavesdrop or tamper with any message. TLS is the successor to the Secure Sockets Layer (SSL).

In 2015, the PCI Council released their findings about TLS and ruled that TLS 1.2 (a more modern and secure Security Layer) should be the model used by everyone by June 2016. They also asked that TLS 1.0 should be scourged from the face of the planet by 2018.

eRatex is perfectly positioned. TLS 1.2 is the default security protocol for .Net 4.5+ and eRatex is natively designed to run in that setting.
