Sage’s Response

When asked how Sage will ensure their customers are applying the patch, VP Product, Rob Sinfield, responded by saying, “We have made best efforts to contact relevant Sage X3 on-premises customers (direct, or via our VAR partners) and advised them of this potential vulnerability and the advised fix, as well as proactively provided the patch through all customer-facing support channels.”

They also offer quarterly updates of relevant security patches. Their own software, as well as 3rd party components, are used to identify these needs. The Sage Representative also expressed that their customers also get regular recommendations for security best practices that they are encouraged to keep up with.
