KashFlow Security Update – TLS

From 15th June 2020 KashFlow will no longer support TLS 1.0 or 1.1. However, we will continue to support TLS 1.2 and higher.

What is TLS?

TLS stands for Transport Layer Security. It keeps your internet traffic secure, displaying a padlock in your internet browser bar when a website is safe. TLS replaced the older SSL (Secure Sockets Layer) protocol.

The current recommended protocols are TLS versions 1.2 or 1.3. TLS versions 1.0 and 1.1 will soon be out of use within the industry.

What are we changing?

KashFlow uses TLS 1.2 by default, but currently allows connections using TLS 1.0 or 1.1. To ensure that your data is as secure as possible we are removing support for these older protocols.

How will this impact me?

  • Google Chrome 38 and higher
  • Firefox 27 and higher
