TLS 1.0 being turned off

Company News/ Security/ 29th Jun 2018/Will Cook-Martin

TLS stands for Transport Layer Security, and it’s a protocol that provides privacy and a secure data link between two communicating applications.

On 1st July 2018, TLS 1.0 encryption protocol will be disabled on our servers, in order to meet PCI compliance. Connections to and from servers will use TLS 1.1 or 1.2 from that date

After 1st July, you may have trouble connecting to our servers if you use an old browser. Please review the table below and if you are using a browser that is incompatible, we recommend you update immediately.
