SNS Notice: Legacy Software Removal from Download Sites December 30, 2022
As part of the Skyhigh Security rebranding journey, we would like to advise all customers that after December 30, 2022, products that do not carry the Skyhigh Security name or brand generally will no longer be available for download through the Product Download Site, Service Portal, ePO Software catalog, and repositories.
Skyhigh Security recommends all customers download any legacy software required for their environment before December 30, 2022.
If you have specific needs after December 30th that aren’t available, contact Technical Support for additional information and assistance.
Try to create a support ticket, maybe they can provide the ISO for you.
