Virtru for Outlook 365 Add-in has several additional configuration options that your organization can leverage. These options give you more control around where Virtru Rules scan and where encryption is actually performed. They also can help improve send performance for both encrypted and unencrypted emails.
Disable Rule Scanning in the O365 Add-in
Virtru offers the ability to disable all client-side Rule scanning in the O365 add-in for your entire organization. This tends to speed up performance of the O365 add-in for unencrypted sends. However, it does mean no Virtru Rules will run or be acted upon in the O365-add-in.
If you have a Virtru Gateway, you can still perform scanning at the Gateway level. If you do not have a Gateway, your emails will not be scanned.
Disable Client-side Encryption in the O365 Add-in
Virtru also offers the ability to disable client-side encryption in the O365 Add-in for your entire organization. This setting pushes the actual email and file encryption to the Virtru Gateway. As a result, a functional Virtru Gateway is a required prerequisite to this configuration.
This configuration usually improves the send time for encrypted emails.
Feature Enablement
Both of the features above have to be enabled by Virtru. To request enablement, please have an account administrator for your organization contact Virtru Support.
