Frequently asked questions about secure emailing.

No, with FTAPI SecuMails even very large data can be sent as e-mail attachments without any problems. The size restrictions of your mail server are not exceeded by storing the attached file(s) encrypted on the highly secure FTAPI server when sending them with FTAPI SecuMails and then adding a download link in the attachment.

No, only one of the two sides (sender or recipient) requires an FTAPI licence for encrypted email communication.

No, the recipient can provide a secure upload link, the so-called submit box, via which external persons can then submit data to the recipient in encrypted form. The link to the submit box can be integrated at various touchpoints, e.g. in the contact area on the website or in the email signature.

By default, when sending with FTAPI SecuMails, the attachment of the message is encrypted. In addition, security level 4 encrypts not only the attachment but also the email plain text end-to-end.

Always. The guidelines and recommendations for digital communication of organisations are constantly becoming stricter. The guidelines are in the self-interest of companies and authorities, as they can minimise risks such as the loss of business-critical data or intellectual property data. Secure e-mail communication must be guaranteed, both internally and across organisational boundaries.

Furthermore, since May 2018, personal data has been subject to an EU-wide legal regulation in the form of the GDPR. Personal data may only be exchanged or made available on the internet in encrypted form. Many company departments work with data of this kind, such as in administration, in the finance department, in the human resources department and even in sales and marketing. Personal content is often included in contracts, personnel documents, general customer communication, orders or invoices. If you have any questions about the GDPR, FTAPI will be happy to advise you!

FTAPI SecuMails can be used conveniently with Microsoft Outlook from within the application by installing the FTAPI Outlook Add-In. The FTAPI WebUI is available for all other mail clients, allowing encrypted messages to be sent via the browser.
