When using Virtru Pro, you can fully control all aspects of any secure email — both before and after you send it. This ranges from message encryption, to setting expiration dates for secure messages you’re sending (or have already sent) with Virtru.

The expiration date feature can be accessed via the Virtru protection bar when you’re composing your secure email. Once set, it will revoke access for all recipients to your email once the selected time has elapsed. Expiration can be updated or disabled at any time.

1. Start by clicking “Compose” to start writing your new email message, then make sure Virtru Protection is togged to “ON”.

Updating Your Expiration Settings From Your Sent Mail Box

Expiration (or any other protection features) can be updated or disabled at any time. You can do this simply by finding the secure email in your Sent Mail Box, opening the sent secure email and updating the time frame in your Virtru Protection Bar.

Virtru’s PDF Watermarking feature adds each recipient’s email address as a watermark to any encrypted PDFs that you attach to a particular Virtru email. When PDF Watermarking is enabled, recipients will be prompted to view all PDF attachments from Virtru’s Secure Reader, and they will not have the option to download the file. Currently, Virtru users cannot enable PDF Watermarking without also disabling downloading of the attachments they send.

When you turn on ‘Disable Forwarding’ to a Virtru email that you’ve already sent out, any future recipients that have that email forwarded to them will be unable to read the contents. However, recipients who had the email forwarded to them before ‘Disable Forwarding’ was turned on will still be able to read the email contents. It is important to note that ‘Disable Forwarding’ only applies to emails forwarded after this policy was selected for a particular email.

If you’ve logged into the Secure Reader previously with a different email address, your browser may have defaulted to that address’s credentials instead of the address that received the current email.  Check which account is currently logged in via the menu in the top right corner of the Secure Reader.  If that’s not the address to which the email was sent, simply click that menu and select the proper address.  If you’re not granted access immediately, just refresh the page.

You won’t be able to send encrypted or unencrypted email, and won’t be able to decrypt encrypted emails.  Any email being viewed in the Secure Reader will be closed.  

Yes. An active internet connection is required to both send and read encrypted emails with Virtru.  If you compose an email while offline and attempt to then encrypt that email you will be presented with the below error message.  Once your internet connection is restored you will then be able to securely send the email and read already encrypted messages.

For most recipients, issues opening your secure emails can be resolved by making a few small changes to their browser settings. For recipients in Chrome, Firefox, or Safari, they’ll just need to make sure they’re not using Private browsing and that cookies are enabled. Here’s how to enable cookies in each of those browsers:

Chrome: https://support.google.com/accounts/answer/61416?hl=en
Firefox: https://support.mozilla.org/en-US/kb/enable-and-disable-cookies-website-preferences
Safari: https://support.apple.com/kb/PH21411?locale=en_US

For users in Internet Explorer, there are a few more settings that can get in the way. Here are the settings that we recommend:

>> Internet Options > Privacy > Advanced: Accept cookies from both first- and third-party sites.
>> Internet Options > Security > Set to “Medium-High” or lower.
>> Compatibility View settings > Ensure Virtru is not on this list, and the box next to “Use Microsoft compatibility lists” is unchecked.
>> Internet Options > Security > Trusted Sites > Sites > Add https://*.virtru.com
