Fortanix Data Security Manager (DSM) 4.36.2574.2905 release provides an overview of improvements.

This release is superseded by the August 28, 2025, release.

WARNING

• You are REQUIRED to upgrade Fortanix DSM to version 4.31 or 4.34 before upgrading to version 4.36.2574.2905. If you want to upgrade Fortanix DSM to version 4.36.2574.2905 from a version earlier than 4.31, please contact the Fortanix Support team at your earliest to validate the upgrade path.

• Downgrade from 4.36.2574.2905 to any prior version is not supported due to the DCAP migration.

• If you are upgrading to Fortanix DSM version 4.36.2574.2905 with the BMC update, you can only upgrade to version 5.0 patch 3, which supports the latest BMC version. Upgrading to a version lower than 5.0 patch 3 will result in the upgrade getting stuck due to an incompatible (lower) BMC version.

NOTE

• The Fortanix DSM cluster upgrade must be done with Fortanix Support on call. Please reach out to Fortanix support if you are planning an upgrade.

• The customer's BIOS version must be checked by Fortanix Support before the Fortanix DSM software upgrade. If required, the BIOS version should be upgraded to the latest version and verified by Fortanix Support for a smooth upgrade.

• If your Fortanix DSM version is 4.31 or later, then the HSM Gateway version must also be 4.31 or later. Similarly, if the HSM Gateway version is 4.31 or later, then your Fortanix DSM version must be 4.31 or later.
