TLS or Transport Layer Security is a cryptographic or encryption protocol that provides secure communication between users' Web browsers and the destination site, for example, RM Unify, O365 or G Suite. TLS version 1.2 or later offers improved security and will generally be used automatically by up-to-date browsers. TLS 1.0 and 1.1 are now recognised as supporting weaker levels of security and may, therefore, be more vulnerable to interception or hacking.
As long as TLS 1.2 is supported and enabled on your device then your browser will automatically use the latest version of TLS when you access RM Unify.
From the end of October 2018, we will be disabling access to RM Unify for TLS 1.0 and 1.1 in line with Microsoft's plans for O365.

This will mean that users will no longer be able to access RM Unify on older, unsupported operating system/browser combinations or on an operating system and browser that has TLS 1.2 disabled. This is most likely to affect Windows 7 client devices, which may not have TLS 1.2 enabled by default.
Our recommendation is that all customers use Windows 10 as this is Microsoft's most up-to-date operating system and already has TLS 1.2 enabled by default.
For CC4 customers who are continuing to use Windows 7, we have developed CC4UPD212 to help network administrators ensure that TLS 1.2 is enabled. More information will be posted on RM Support Online when this update is ready.
For other customers, we recommend that you follow the instructions provided by Microsoft to ensure that all of your Windows 7 computers have TLS 1.2 enabled:
