About this release
Version 5.9 of DRACOON for Outlook for DRACOON cloud users contains a major new feature: Full encryption for emails via DRACOON.
In addition, a display problem for French-speaking users has been fixed.
Full email encryption
With the new full email encryption, DRACOON for Outlook offers a highly secure method for sending emails that have special security requirements. The term full encryption refers to the fact that both the email message itself and any file attachments are encrypted on the client-side before being delivered to the recipient via DRACOON.
How does full email encryption work?
- If full encryption is activated for a specific email, the email message is automatically converted into a client-side encrypted PDF file on the sender's PC.
- The PDF file is then uploaded to an encrypted data room in DRACOON together with any attachments of the email.
- The actual email message with attachments is not sent via Outlook—instead, the recipient automatically receives a notification email with a password-protected share link where he can securely download the PDF file with the email message and, if necessary, the file attachments from DRACOON. When downloading, they are decrypted by entering the password and can then be opened by the recipient.
Even if the internal processes of full email encryption are complex, it is still easy and convenient to use for both sender and recipient. Compared to regular email, only one additional step is necessary: The sender just has to specify or have a password generated for the email and forward it to the recipient manually (e.g. via chat) so that the recipient can decrypt and open the email using the password. Everything else is done automatically by DRACOON for Outlook.
What are the benefits of full email encryption?
- Content and attachments of an email that were fully encrypted by DRACOON for Outlook are not sent via your regular mail server and therefore cannot be accessed by server administrators.
- Furthermore, they are not stored in the recipient's mailbox, so that no data can be leaked by server administrators, for example, on the recipient side.
- Client-side encryption ensures that content and attachments of the email are already securely encrypted on the sender's PC before they are uploaded to DRACOON—due to the client-side encryption, even DRACOON personnel would not be able to decrypt the email under any circumstances.
- An expiration date can limit the availability of the email so that it cannot be downloaded and opened by the recipient afterward. If necessary, the share of the email can also be terminated at any time by deleting the share link.
- Sender and recipient do not have to exchange certificates, as is required for the mail encryption included in Outlook (via S/MIME). The sender only has to forward the share password to the recipient.
