Email encryption with Outlook

Convenient email encryption in Outlook – efficient and reliable with FTAPI software.

End-to-end email encryption without detours with the Outlook add-in.

Do you want to encrypt your emails without leaving your usual Outlook mailbox or even switching to another software solution? Outlook is probably one of the most used applications in the corporate environment. However, when you need to send large files securely, the email program quickly reaches its limits. It is not possible to either send data in encrypted form or securely receive large and/or sensitive files without an additional plugin in Outlook.

Data protection guidelines in Germany and Europe are becoming increasingly stringent. At the same time, many companies still do not send their emails and sensitive file attachments in encrypted form. FTAPI offers an efficient and secure solution for this: send sensitive file attachments of any size easily with the FTAPI SecuMails Outlook add-in. The Outlook add-in is based on highly secure encryption technology – coded & hosted in Germany.
