4 September 2018 - TLS Strengthening for .UK Registrars

We are pleased to announce the deployment date for the implementation of Strengthened TLS requirements for .UK EPP connections. 

In line with recognised best practice for EPP connection security we are increasing the minimum version of TLS that registrars must use for their EPP connections to v1.2.

Strengthened TLS for EPP connections requirements will be deployed on 4 September 2018.

The UK testbed (Operational Test and Evaluation - OT&E) will be updated on 5 June 2018 so that registrars may test their connections meet the new requirements.

What action do I need to take?

We strongly advise registrars to check that they are using TLS 1.2 for all EPP connections.

From 4 September 2018 you will need to use TLS 1.2 for your EPP connections and connections attempted using lower TLS levels will fail.
