What's new in Agent 5.3.0
Posted on July 07, 2026
Forcepoint Data Classification (FDC) 5.3.0 introduces a long-awaited feature for enterprise administrators: fully customizable messages for end-user policy dialogs, giving organizations control over how data classification policies are conveyed to their users. The release also broadens Microsoft Purview (MIP) integration, enabling encryption and rights management policies to be enforced directly on endpoint files. In addition to these enhancements, 5.3.0 ships a substantial round of bug fixes that strengthen classification reliability across Outlook, Excel, Word, PowerPoint, and macOS - resolving both internally discovered issues and open customer escalations.
New Features and Enhancements
Custom Agent Messages (DEL-2052)
Custom Agent Messages is one of the most impactful admin-facing features in FDC 5.3.0, giving administrators complete control over the messaging end users encounter whenever a data classification policy is triggered. Until now, every dialog message - whether a block notification, justification prompt, print warning, or recipient limit alert- was hardcoded, leaving organizations no way to tailor them to their own context.
Administrators can now view, edit, and manage the entire library of agent messages straight from the FDC dashboard under . Updates apply without reinstalling the agent or restarting the system, the platform reverts to built-in defaults whenever no override is defined, and configurations from earlier versions are migrated automatically.

Microsoft Purview (MIP) Policy Integration (DEL-2049)
FDC Agent 5.3.0 builds on existing Microsoft Purview sensitivity label support to enforce Purview policies - including encryption and RMS-based protection- directly on endpoint files. Administrators set up MIP credentials and label mappings through the Endpoint module in the FDC dashboard, and any previously applied MIP label is properly removed when switching to a tag that has no mapping.

Mail Merge Support with Microsoft Word (DEL-2578)
FDC Agent 5.3.0 adds improved compatibility with Microsoft Word's Mail Merge feature, ensuring bulk email campaigns sent via Outlook are delivered reliably while the FDC Agent is active. This extends consistent classification behaviour to one more common enterprise workflow.

Signed PDF Classification Handling (DEL-2596)
FDC now correctly excludes digitally signed PDFs from classification. Attempting to classify a signed PDF now surfaces a popup informing the user that classification isn't available for that file, consistent with the existing experience for empty or protected files, preventing signature invalidation.
