Technical Advisories v2.5
Windows v2.5
• Currently, if the administrator enables or disables the File Icon Overlay policy, users must manually refresh any opened File Explorer to
view the correct file overlay behavior. If enabled and the overlay icon does not display for users, the administrator can navigate to the
Microsoft Registry,
HKLM\Software\Microsoft\Windows\CurrentVersion\Explorer\ShellIconOverlayIdentifiers. Rename
the Data Guardian OverlayIconExt key to move it within the top ten registry keys for that folder, for example, by adding spaces to
the beginning. [DDPCE-11931, DDPCE-12648]
• Rarely, if you manually activated against a SaaS server, sometime later your computer may not create or open protected documents.
The workaround is to right-click the
Data Guardian icon in the notification area, press Ctrl-Shift and select Details, then click
Deactivate. To reactivate with SaaS credentials, click the Data Guardian icon in the notification area and click User Activation.
[DDPCE-12752]
Mac v2.5
• For Mac Data Guardian, to avoid security issues with XML eXternal Entity (XXE) Injection attacks, be sure your Mac operating system
has libxml2 2.9.4 or higher installed. Typically, this is automatically installed with macOS Sierra 10.12.6 and higher. [DDPCE-12629]
• Mac Data Guardian has security measures, but if the cloud storage provider's login page is compromised, it could cause a redirect to
an insecure site where data loss could occur. [DDPCE-12659]
• Be aware that, in some places, the cloud storage providers API involves HTTP Get instead of HTTP Post. [DDPCE-12660]

New Features and Functionality v2.4
Windows v2.4
• For Workspace ONE and MSI installations, Visual Studio C++ 2017 Redistributable Package is required.

data in audit events and embargo files are not supported. Web beacon is supported with additional configuration.
• A red outline border displays for protected Office documents and emails.
• For protected Office documents, the right-click option has changed from Grant Protected File Access to Protected File Access.
• Currently, Data Guardian's Cloud Encryption protection has been disabled on Windows to prevent compatibility issues with newer

Data Guardian's Mobile app, web
portal, or Data Guardian with Mac.
