    How To Encrypt Email Attachments

    There are a few different ways to encrypt emails, starting from the broad network-level protection called TLS . Most major email providers have TLS encryption baked in, which protects your emails in transit or within the providers servers. However, TLS doesnt provide complete security: emails outside the server or individual attachments arent protected.

    The next level of protection is end-to-end encryption. This security protects your emails from point-to-point, so no matter where those emails end up, theyre still secure. When you send an attachment that is encrypted end-to-end, the file is converted into a format that is unreadable without a digital key. When the recipient clicks on the attachment, the encryption server checks to make sure youve given that person permission to access it. The intended recipient can then save and open the fileprovided they can decrypt it. Anyone trying to intercept the file along the way, however, will be stuck with the unreadable data, instead of a photo or other sensitive document.

    One of the most effective ways to enable end-to-end protection is with the Trusted Data Format , created by Virtru CTO Will Ackerly. TDF is a powerful way to protect and control access to highly-sensitive intelligence information, because it can safely encrypt any type of file.
