Frequently asked questions about secure e-mail delivery
Is there a size limit for FTAPI SecuMails analogous to normal e-mail delivery?
No, with FTAPI SecuMails even very large data can be send as an e-mail attachment without any problems. The size restrictions of your mail server are not exceeded by storing the attached file(s) encrypted on the high-security FTAPI server when sending with FTAPI SecuMails and then adding a download link in the attachment.
Do the sender and the recipient need an FTAPI licence to send encrypted e-mails?
No, only one of the two sides (sender or recipient) requires an FTAPI licence for encrypted e-mail communication.
Does an external user necessarily need an FTAPI account to send data?
No, the recipient can provide a secure upload link, the so-called Submit-Box, which external persons can then use to submit encrypted data to the recipient. 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.
What is encrypted when sending with FTAPI SecuMails?
By default, the attachment of the message is encrypted when sending with FTAPI SecuMails. In addition, in security level 4 not only the attachment but also the plain text of the e-mail is encrypted end-to-end.
When is it worthwhile to send e-mails encrypted?
Always. The specifications and recommendations for digital communication of organizations are constantly becoming more stringent. The guidelines are in the self-interest of companies and authorities, as risks can thus be minimized, such as the loss of business-critical data or intellectual property data. It is important to ensure secure e-mail communication, internally and across organizational boundaries.
In addition, an EU-wide legal regulation has applied to personal data since 2018 with the GDPR. Personal data may only be exchanged or made available in encrypted form on the Internet. Many business departments work with data of this type, such as in administration, finances, human resources and even sales and marketing. Personal content is often contained in contracts, personal documents, general customer communication, orders and invoices. If you have any questions about the GDPR, FTAPI will be happy to advise you!
With which mail clients does FTAPI SecuMails work?
FTAPI SecuMails can be conveniently used with Microsoft Outlook from the application by installing the FTAPI Outlook add-in. The FTAPI WebUI is available for all other mail clients, whereby the encrypted message is sent via the browser.
