Reference Guide

• Data Loss Prevention (DLP) now focuses on Data Guardian's mobile clients and web portal. In Windows, some workflows have been
reenabled to improve performance. Therefore, the following policies no longer apply for Windows in Data Guardian v2.8 and higher:
• Block Print Screen
• Print Control
• Export Control
• Protected Office Document Process Protection
• Protected Office Clip Board Unauthorized Text
• On Screen Watermark
• No red border displays on protected Office documents or protected emails.
• With Access Groups in an on-prem environment, an administrator can set an additional policy to allow the owner of a file to right-click
an Outlook email that they protected and sent to users in their
access group. The owner of a file can remove an individual's access to
that email.
Mac v2.8
• macOS Mojave 10.14.6 is now supported.
• External users can no longer install Data Guardian or upgrade an earlier version to v2.8. External users can install Data Guardian on an
iOS or Android mobile client or the web portal to view encrypted files.
Mobile v2.8
• iOS 12.3 is now supported.
Web Portal v2.8
• OneDrive for Business has a Save to cloud storage provider option.
Technical Advisories v2.8
All Platforms v2.8
• In an on-prem environment, Data Guardian clients must be able to communicate with the Security Server with the correct protocol,
name of the Dell Server, and port, for example https://server.domain.com:8443. Port 8443 is the default. If an enterprise uses a
customized port, the administrator must inform users. [DDPCE-14562]
Windows v2.8
• If a user removes the Data Guardian plugin from Outlook, the user may need to uninstall and reinstall Data Guardian to enable the
plugins. Administrators should clarify that users should not remove the Data Guardian plugins. [DDPCE-6198]
• If Data Guardian is installed to a non-default location, for example, C:\Data Guardian, the Office plugins are not automatically installed
and a dialog states Publisher cannot be verified. The installer must select Install or Don't Install. [DDPCE-13231]
• Recent updates to Adobe Reader DC have modified its signing signature, which is to verify the application. Data Guardian can no
longer verify the integrity of the updated Adobe Reader DC, so Adobe Reader DC is blocked from launching to protect sensitive data.
Dell is working with Adobe on a permanent resolution. The current workaround is to leverage Adobe Reader 19.10.20098.316574 or
earlier. To find previous releases of Adobe Reader DC, see:
https://supportdownloads.adobe.com/product.jsp?product=10&platform=Windows. [DDPCE-13627]
• Data Guardian has been tested and functions as expected with Windows 10 Defender Exploit Guard, Credential Guard, or with
Hypervisor-protected code integrity (HVCI) enabled. [DDPCE-13701, 13702]
• Currently, if email encryption is enabled and a user selects Share on an open, unprotected PDF and then attaches it to Outlook email
and sends it as unprotected, the recipient may see an error dialog and not be able to open the PDF. Until resolved, users should attach
the unprotected PDF directly in Outlook. [DDPCE-14168]
• For on-prem with Access Groups enabled, when right-clicking an encrypted PDF and selecting Protected File Access, the pre-share
user interface may not display. To work around this issue, place the encrypted PDF in a cloud storage provider and select Protected
File Access. [DDPCE-14253]
• When email encryption is enabled and a user selects a [PROTECTED] email from the Inbox or Sent Items and then selects Actions >
Resend This Message, the sender must then close the Resend window and is prompted to save the changes. If the sender clicks
No, the preview pane of the [PROTECTED] email is unprotected and without the cover page. [DDPCE-14476]
• Data Guardian and Microsoft's Azure Information Protection (AIP) are not mutually compatible. If a user protects an Office document
with AIP and then uses Data Guardian's right-click or Protected Save As to protect the document an error dialog displays and the user
cannot open the protected document. [DDPCE-14491]
