Announcement: End of Support for TLS 1.0 and 1.1.

Published Jan 27, 2020

Experienced developers, cyber-security experts, ALM consultants, DevOps gurus and some other dangerous species.

On March 1st Kiuwan will disable support for TLS 1.0 and 1.1.


Only 3% of our systems traffic uses TLS 1.0., so we have decided to disable support for it from March 2020 onwards.

What is TLS? 

As described by Microsoft:

  TLS 1.0 is a security protocol first defined in 1999 for establishing encryption channels over computer networks. Microsoft has supported this protocol since Windows XP/Server 2003. While no longer the default security protocol in use by modern OSes, TLS 1.0 is still supported for backwards compatibility. Evolving regulatory requirements as well as new security vulnerabilities in TLS 1.0 provide corporations with the incentive to disable TLS 1.0 entirely.

What does this mean for us? 

When you connect to Kiuwan using a client (browser or mobile app) that uses a TLS version before 1.2, your information (password, messages, etc) will be at risk of being exposed.

What should I do?

Simply upgrade before March 1st, 2020 if you are using an old browser or app. That’s all!

For any further questions, please contact our support team.
