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”.

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.

Virtru’s encryption complies with FIPS 140-2, but not always by default. Customers should make sure to request Virtru with FIPS mode enabled to ensure FIPS 140-2 compliance across all Virtru platforms.

We use 3rd party AES-256 encryption libraries that have been certified by or for companies such as Google, Apple and Microsoft (more details below). As such, Virtru has not been required to go through a validation directly.

The Certificates for the certified Cryptographic Libraries are all listed here. The certificate numbers in question depend on platform and are listed below:

– # 1329 – Outlook for Desktop – Windows 7
– # 2357 – Outlook for Desktop – Windows 8
– # 2021 – iOS
– # 1747 – Android, Chrome*

*Upon request, we can enable FIPS mode in Virtru’s Chrome extension, but that platform does not use a FIPS module by default today.
