The Trellix Drive Encryption - SaaS 8.1.2604 release includes new features and resolved issues.

Every update release is cumulative and includes all features and fixes from the previous release.

Important

Before installing the Trellix Drive Encryption 8.1.1 client package, administrators must update the Secure Boot database with "Microsoft UEFI CA 2023" and "Microsoft Option ROM UEFI CA 2023" on all Windows 10 and above systems. If the UEFI secure boot database is not updated with CA 2023 certificates, the upgrade to Drive Encryption 8.1.1 will abort. For more information, see article 000015304.

For customers also using Trellix Native Drive Encryption, prior to initiating any Secure Boot certificate updates, we strongly recommend that you verify that recovery keys are accessible in every system. Customers may be impacted by a known issue when a cloud native identity management system is in use on the endpoint, such as Entra ID (Azure AD). Endpoints with only Active Directory users are not affected. Key availability can be verified in ePO. For more details, see article 000015395.
