Effective September 2023, Sage servers will stop accepting communication from Sage 100 and
Sage 300 product versions using Transport Layer Security (TLS) 1.0 and 1.1.
TLS is a security protocol that creates encryption paths over computer networks to help ensure
that online communications and information cannot be intercepted. Regulatory standards have
increasingly required the adoption of TLS 1.2 and the subsequent deprecation of TLS 1.0 and 1.1
due to known security risks.
Any subscription customer on product versions using TLS 1.0 and 1.1 will require an upgrade to
their Sage 100 and Sage 300 software to prevent a disruption in the use of their software.
If a customer does not upgrade their software by September 2023, they will begin receiving
warning messages when accessing Sage 100 and Sage 300 due to the inability to communicate
with Sage servers. The software will revert to read-only mode and restrict access.
We encourage all customers to remain on current software versions to ensure that you realize the
full benefits from enhancements and updates, as well as to help prevent disruptions that may
result from mandatory security updates.
