In a recent update Apple announced that support for TLS1.0 and TLS1.1 will be deprecated as of iOS 15, iPadOS 15, macOS 12, watchOS 8, and tvOS 15. Support for these insecure versions of TLS will be removed entirely in future releases. Apple specifically recommend supporting TLS 1.3.
The latest version of TLS, TLS 1.3, provides enhanced security and fewer ways for attackers to find new flaws. TLS 1.3 has also been shown to improve performance, with secure connections taking less time to be established. The development and deployment of TLS1.3 demonstrates that performance optimizations can be made without compromising on security. Improving the security of Internet applications of all kinds is imperative for a healthy and growing Internet. Follow the adoption of TLS1.3 on our Pulse Enabling Technologies page.
