Real-world email security – is TLS the answer?
Mar 04, 2020 · The first stages of this deprecation began last year when browsers began labeling sites that were using TLS 1.0 and TLS 1.1 with a "Not Secure" indicator in the URL address bar and the lock icon Apr 03, 2019 · Secure Sockets Layer (SSL) and Transport Layer Security (TLS) are cryptographic security protocols. They are used to make sure that network communication is secure. Their main goals are to provide data integrity and communication privacy. The SSL protocol was the first protocol designed for this purpose and TLS is its successor. To improve the security of connections to Citrix Listener Service used for Secure Mail notifications, Citrix will block any communication over Transport Layer Security (TLS) 1.0 and 1.1 as of July 31st, 2020. TLS 1.1 dates back to 2006, and shortly after, TLS 1.2 was developed to address numerous security concerns in TLS 1.0 and TLS 1.1. TLS 1.2 is still secure to this day, TLS 1.3 has been released with improvement to both security and performance.

Since SSL’s first iteration back in 1995, new versions of each protocol have been released to address vulnerabilities and support the strongest and most secure cipher suites and algorithms. We are currently on TLS 1.3, which was approved by the IETF (Internet Engineering Task Force) in March of 2018.
