Virtru

U-M faculty, staff, and students can add an extra layer of security to their already secure U-M Gmail email messages by using Virtru. Virtru includes a number of security features and options to encrypt your email and help you control access to the email that you send when using the tool.

Virtru allows you to send end-to-end encrypted email. You choose whether to turn encryption on for each email that you send. With Virtru you can see whether the recipient has opened the email, prevent a forwarded email from being read, set an expiry date beyond which the email cannot be read, revoke the ability to read an email after it has been sent, and more.

Michigan Medicine Outlook/Exchange users can instead use Michigan Medicine's Outlook - Email Encryption (U-M login required) to encrypt email attachments.

For best results, use the Chrome browser extension. Other options are also available.
