TLS 1.0 and 1.1 deprecation update: Maintaining the highest levels of security and reliability

Transport Layer Security (TLS) is a critical security protocol that protects internet communications like email, chat, and payments from eavesdropping and tampering. It has been announced that TLS 1.0 1.1 will soon be deprecated.

TLS encrypts data that moves between clients and servers, like when you get on a video call or buy something online, helping to make sure that your data stays confidential and isn’t changed in transit. The Internet Engineering Task Force (IETF) first defined the TLS protocol in 1999. Although the earliest TLS protocols were one of the key drivers of the internet boom, many things have changed in the past two decades.

As part of ongoing efforts to improve security and reliability, TLS 1.0 and 1.1 have been deprecated by the IETF as of March 25, 2021. In computer programming, “deprecation” is the process of marking older code as obsolete and discontinuing its use because it has been replaced by newer and better-performing code. In order to ensure the highest level of security and customer experience, Paybook and Syncfy will stop supporting TLS 1.0 and 1.1 as of October 22, 2021. 

If your app continues to use legacy TLS 1.0 or 1.1, please make plans to transition to TLS 1.2 or later. We recommend supporting TLS 1.3, as it’s faster and more secure. Please verify that your application supports the later versions and make sure to remove any deprecated protocols from your app.
