This release introduces new features or improves existing features:

Setting the confidence threshold in manually registered documents - Trellix Data Loss Prevention allows you to configure the number of fingerprints that must be matched in a manually fingerprinted document to trigger a violation. This helps in increasing the detection confidence as it minimizes false positives by triggering more accurate detections and reduces the analysis time.

An incident is triggered when the number of matches is equal to or higher than the set confidence threshold. You can set the Confidence Threshold percentage between 10 to 100 percentage. For example, if a fingerprinted document generates 100 signatures, and if you select 10%, then 10 signatures are matched at random in the scanned document.

To set the threshold percentage go to, Classification → Register Documents → Manual Registration → Confidence Threshold.

Adding visual labels to Microsoft Office documents- Visual labeling is a document labeling solution for Microsoft Office documents (Word, Excel, and PowerPoint) that forces users to manually select the classification before saving a document. You can use this method to display visual labels in the header, footer, and watermark of the document as supported by Microsoft Office applications to identify its sensitivity and label the document without the use of third-party tools. For more information on visual labeling, see the Classifying files manually topic in the Product Guide.

Enhanced screen capture protection - Screen capture actions performed using Universal Windows Platform apps, such as Snip & Sketch are now protected by Trellix DLP Endpoint.

Block Gen AI URLs - Web Application Control feature in Trellix DLP Endpoint now allows you to block access to generative AI websites. To block a new generative AI website go to, DLP Policy Manager → Definitions → URL List → Action → New.

Monitor text upload to Gen AI prompts - In the web protection page, you can now add web URL tags in order to monitor text uploads to the generative AI website. As a result, corporate devices can be monitored in order to avoid sensitive data leak. For additional information on finding tags for other websites, see KB96881.

Support for Island Browser - This beta release feature for Island browser supports the Web protection rules, Printer protection rules, Clipboard protection rules, and screen capture protection rules that monitor or protect the activities in Island browser. For additional information on the Island browser support, see KB96904.

Drag and drop - This release provides you with an option to optionally disable drag and drop of attachments from Microsoft Outlook into supported Chromium browsers.
