TLS end of life: How it impacts you and your Sage system

TLS end of life: How it impacts you and your Sage system


What is TLS?

TLS, or Transport Layer Security is a cryptographic protocol designed to provide communications security over a computer network. In simple terms, TLS is a handshake between an application and a server. There are 4 versions of TLS; 1.0, 1.1, 1.2 and 1.3.

TLS End of Life

Due to the age of TLS 1.0 and TLS 1.1 (22 and 15 years old respectively) and because they are compromised, the big 4 browser and operating system providers (Apple, Mozilla, Google and Microsoft) have all dropped support for TLS 1.0 and TLS 1.1 leaving only TLS 1.2 and 1.3 active. 

Any application that still relies on TLS 1.0 or TLS 1.1 will no longer work.

How does this impact you?

The security of our customer’s Sage products is of paramount importance. Within Sage, TLS enables product installations, licencing as well as API and 3rd party integration with Sage software. In some instances, TLS will be used to encrypt traffic to allow Sage to communicate securely over external networks. Sage has announced a round of routine maintenance in response to the deprecation of TLS 1.0 and TLS 1.1 from its range of supported software. 

Sage 200 Software updates

Sage will be providing software updates for those affected by this planned withdrawal, which will ensure product security is not compromised.

The steps you’ll need to take vary depending on the Sage 200 version and/or connected services combination. The recommended action varies by version, please refer to the table below for detail.

How does this impact CPiO Cloud?

As a security conscious business, CPiO closely follows security best practices.

All webservers and applications must also use TLS 1.2 or 1.3 and so CPiO Cloud servers have been upgraded to support this where possible with current application versions. 

CPiO will take care of any forthcoming updates for CPiO Cloud customers in line with the CPiO Cloud T&C’s, ensuring customers continue to operate securely. 

If you have any questions, please don’t hesitate to contact us.
