When Virtru protection is toggled off, users can add up to 150 attachments before toggling Virtru on. Once Virtru is on, additional attachments may be added. The total size of all attachments cannot exceed 150 MB. Please note, this maximum is for the sum of all attachments and not per attachment (ex. two attachments of 100 MB would be too large).
This includes the following products:
Virtru Chrome extension
Virtru for Outlook Desktop
Virtru Secure Reader
Virtru for Mobile
Virtru On Prem Gateway
Virtru Hosted Gateway (outbound)
Virtru for Google Drive supports different maximum file sizes than our email-based products. Visit our File encryption limits for Virtru for Drive article to learn more.

Note:
When Virtru is disabled/off, attachment size varies by email provider. This especially pertains to Exchange accounts where the attachment size can be modified by the administrator.The exception to this is our Virtru Hosted gateway (inbound mode) which currently supports up to 50MB attachment size
