to email encryption
via a simple Outlook Add-In
Automatically convert email attachments of any size into download shares
and send them encrypted as well as GDPR-compliant
“I’ll e-mail you the contract.” – Everyone has probably heard this sentence before.
Because email is still the most popular way to exchange information and files.
But hardly anyone is aware that all information is sent in plain text.
This is particularly devastating in the business environment, as emails and email attachments can be intercepted with relatively little effort.
Classical email encryption programs are very complicated
Many companies are therefore looking for a solution to send sensitive files securely and GDPR-compliant by email.
The two most common forms of classic email encryption are the asymmetric encryption methods S/MIME (Secure/Multipurpose Internet Mail Extensions) and PGP (Pretty Good Privacy).
These forms of email encryption use asymmetric encryption, in which two keys are used that must match. To encrypt a mail, a public key is used; the recipient of the mail needs the corresponding private key to decrypt it. This procedure has the advantage that not only the mail content itself is encrypted, but it is also guaranteed that the sender is authenticated as the one he claims to be.
If you want to use these procedures in practice to send an encrypted email to contacts, you must therefore install a security certificate on your computer and give your contacts a so-called “public key”. At the same time, however, the recipient must also have an appropriate certificate installed and send you the public key so that you can receive emails again.
In May 2018, security experts published a vulnerability in email encryption (Efail) with OpenPGP and S/MIME. Encrypted emails were vulnerable to attacks in the email programs Microsoft Outlook, Apple Mail or Thunderbird. It cannot therefore be ruled out that security vulnerabilities will occur again in the future.
Classic email encryption programs that use these encryption forms and encrypt the entire email are therefore rather complicated to use, since the emails often have to be retrieved via an extra portal.
However, it is often not even necessary to encrypt the entire mail, since the sensitive information (such as the contract mentioned at the beginning) is in the attachment of the mail. It must therefore be ensured that the attachment in particular is delivered in encrypted form.
Simple solution for email encryption with DRACOON for Outlook
DRACOON has developed a modern Outlook Add-In for email encryption that makes everyday communication simple and secure:
The file attachments are stored on a platform for secure information exchange. There they are protected by comprehensive measures such as end-to-end encryption and password protection. The mail attachments are sent as encrypted download links.
In contrast to pure transport encryption, end-to-end encryption does not encrypt the individual sections in the dispatch channel, but each individual release link itself. In order to download the content of the release link, the corresponding password must be entered. This can, for example, be transmitted directly from DRACOON via SMS.
Therefore, only the sender and recipient can view the download release. Neither DRACOON as the software provider can decrypt the release link, nor do potential attackers have the possibility to manipulate the emails on the way. Thus only this technology fulfils the three goals of the GDPR: Confidentiality, authenticity, integrity.

This allows you to communicate easily and securely by email – and at the same time have full control over your files.
