Together with Google, Microsoft and Mozilla, Apple will discontinue the use of TLS 1.0 and 1.1 until the beginning of 2020. TLS stands for Transport Layer Security and serves to protect web traffic. ArsTechnica reported the agreement for the first time, while Apple's WebKit blog also described the change.

In a post on the WebKit blog, Apple's Secure Transport team stated that TLS provides confidentiality and integrity of data transmitted between clients and servers:
Transport Layer Security ( TLS) is a critical security protocol used to protect web traffic. It provides confidentiality and integrity of data during transmission between clients and servers that exchange (often sensitive) information. To best protect this data, it is important to use more modern and more secure versions of this protocol.
TLS 1.0 was first released in January 1999, TLS 1.1 followed in 2006. Last, TLS 1.3 was finalized this year in August.
Apple's Secure Transport team further states that the latest TLS 1.2 release provides "security for the modern Web" and is already standard on Apple platforms. Currently, TLS 1.2 represents 99.6 percent of TLS compounds from Safari, Apple says. On a broader scale, 94 percent of sites support TLS 1.2.
Now is the time to make that transition. Properly configured to comply with the Transport Security (ATS) app, TLS 1.2 provides security for the modern Internet. It is the standard on Apple platforms and represents 99.6% of Safari's TLS connections. TLS 1.0 and 1.1, which date back to 1999, make up less than 0.36% of all connections.
Safari on macOS and iOS will completely discontinue support for TLS 1.0 and 1.1 in March 2020. Microsoft, Google and Firefox are subscribing to
