TLS stands for “Transport Layer Security.” It is a protocol that provides privacy and data integrity between two communicating applications and it’s what the ‘s’ in HTTPS is all about. It’s the most widely deployed security protocol used today, and is used for web browsers and other applications that require data to be securely exchanged over a network. TLS ensures that the connection from your browser to our site is secure. However, older versions of TLS have been shown to have security weaknesses, and are therefore being deprecated by all websites which transact payment information.
30th June 2018 is the deadline for disabling early TLS and implementing more secure versions such as TLS 1.1 or higher, as encouraged by the PCI Data Security Standard (PCI DSS) for safeguarding payment data.
