Data Mask Managed Package End of Support

Original Publication Date: January 22, 2026
Updated: May 19, 2026

Salesforce will end support for the existing Data Mask managed package on December 31, 2026, as a new version of Data Mask & Seed becomes available with the Summer ‘26 release (available to all customers by July 1).

A Beta version will be available on April 9, 2026 for customers based in AMER (not on GovCloud) to begin using.

This new version, available as a Core application that requires no installation and we strongly encourage customers to transition to the new Data Mask & Seed upon its release and availability.

Salesforce is prioritizing the development of a modern user interface, extensible, low-code automation solution. This architectural shift addresses current limitations in complexity, error visibility, and scalability, while maintaining security and compliance. It also integrates the Own Accelerate and Seed functionality with Salesforce’s Data Mask into one product and interface. 

What does this change mean for me? 

The new Data Mask & Seed offers a significantly improved, user-friendly experience with a redesigned UI, and several new key enhancements and benefits:

• No Installation Required: It is a Core app, eliminating the need for a managed package.

• Proactive PII Detection - Automatically identifies policy object fields containing Personally Identifiable Information (PII) and suggests a suitable "Mask with" option for them. This provides a significant head start, dramatically reducing the manual effort required for configuration.

• Enhanced Performance: Features improved scalability and performance.

• Informative Error Messages - Error messages are informative and precise, providing details such as problematic record IDs and offending fields. Additionally, including a link to explanations for common errors would significantly speed up self-service troubleshooting.

• Data Integrity: Preserves the sandbox's existing distribution of field values across object records for each field type. Ensuring applications and reports that depend on data distribution patterns will continue to work correctly with the masked data.

• Seeding: New seeding functionality will be integrated into this new UI for a more seamless experience, including Data Cloud seeding and AI seeding (seeding fake data).

• Innovation: New functionality, such as the enhancements mentioned above, will only be available through this new version.

What action can I take? 

No action is currently required until the new version becomes GA with the Summer ‘26 release.

To use the new version once available, you will simply need to create new masking policies in the new Core app to replace your existing masking configurations as there will be some new functionality. Custom Libraries do not require migration or recreation, as they are unified between both the managed package and the Core application. We will provide detailed documentation and a video with guidance in March.

Once policies have been transitioned, you can uninstall the managed package by referring to the Uninstall a First-Generation Managed Package instructions.

On April 9, 2026, customers based in AMER (aside from GovCloud) can begin using the new Data Mask & Seed Beta version. Note: during the Beta phase, the following features will not be available:

• Automation Management: The application will not automatically bypass Salesforce automations (Workflows, Triggers, Validation Rules). Users must manually disable these automations before running a masking job and manually re-enable them after the job is complete.

• Object Filters: Users will not have the ability to use filters to select a subset of records for masking.

• GovCloud Availability: Only the General Availability (GA) version will be offered in GovCloud and will have FedRAMP High certification.

Starting with the Summer ‘26 release by July 1, this version will be GA for all customers in all regions to transition to.
