(TLS) is a protocol that provides privacy and data integrity between two communicating applications. It’s the most widely deployed security protocol in use today, and is used for Web browsers and other applications that require data to be securely exchanged over a network (including the Internet). The newest and most secure version of this protocol is 1.2.
2. Why am I unable to connect to the payment page/frame (or any specific banking application)?
Generally speaking, all payment and banking applications will require TLS 1.2 effective June 30, 2018. All newer versions of the major Internet browsers provide the option for using TLS 1.2.
3. What operating systems and browsers support TLS 1.2?
Operating Systems:
Windows XP and Vista can only upgrade to Internet Explorer 8, which does not support TLS 1.2. However, users of these operating systems can still install a newer version of Firefox, which does support TLS 1.2. Chrome no longer supports Windows XP as of April 2015.
Windows 7 and above can support TLS 1.2.
Browser Versions:
Microsoft Edge (all versions)
Internet Explorer 9, 10 & 11
