Sage 100 Requires TLS 1.2 Use Effective October 2023

Important notice for Sage 100 clients on versions older than 2020.1, 2019.4 or 2018.10

If your organization is still running a version of Sage 100 that uses TLS (Transport Layer Security) 1.0 or 1.1, take note. As of October 2023, Sage will no longer support TLS 1.0 and 1.1. In fact, Sage servers will stop accepting communication from Sage 100 product versions using TLS 1.0 and 1.1.

Here’s more on what that means and your next steps.

What is Transport Layer Security (TLS)?

Transport Layer Security (TLS) is a protocol designed to provide secure communication over the Internet. It encrypts data transmitted between a client and a server, preventing anyone from intercepting or tampering with the information.

Who needs to upgrade?

Any customer on product versions using TLS 1.0 and 1.1 will require an upgrade to their Sage 100 software to prevent a disruption in the use of their software.

What versions of Sage 100 support TLS 1.2?

During 2019, new releases of Sage 100 began supporting TLS 1.2. This means 2018.10, 2019.4, 2020.1, and newer versions have built-in TLS 1.2 support. If your business is not on one of these releases, you must upgrade to a version that utilizes TLS 1.2.

What happens if I don’t upgrade?

If you do not upgrade your software by October 2023, you will begin receiving warning messages when accessing Sage 100 due to the inability to communicate with Sage servers. If the software cannot communicate with the Sage servers, it cannot receive updated information from Sage. Without valid communication for a period of time, the software will restrict access and become read-only.

Why is Sage doing this?

TLS 1.0 and 1.1 were replaced by TLS 1.2 starting in 2008 to provide improved data security and better protection for customer and application information communicated over the Internet. Many companies and standards (e.g., HIPAA, PCI) require TLS 1.2, as do many Sage ISVs. This move to TLS 1.2 will provide increased data protection and decreased risk.

What do I need to do next?

If your organization currently runs a version of Sage 100 that is not at least 2018.10, 2019.4, or 2020.1 and newer*, you must upgrade. We are here to help with that process.
