At Split, we pride ourselves on our security-focus. We’ve kept customer data security a number one concern since day one. With this focus in mind, we are in the process of deprecating non-secure versions of TLS (1.0 and 1.1) in preparation for a broad market deprecation of legacy TLS. Beginning on February 16, 2021 Split will only support TLS 1.2.
Transport Layer Security (TLS) 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 passed between them.
Happily, a very small fraction of the traffic (less than 0.003%) was still using TLS 1.0 and 1.1 which validates the timing for this deprecation.

If you’re already a paying customer using Split, good news! You’re already using an SDK version that supports TLS 1.2.
