Frequently asked questions about email encryption.
Most email programs send messages – including important attachments – unencrypted. This means that the contents are openly visible to unauthorised individuals, much like a postcard. When sending emails with FTAPI, transmission encryption using HTTPS via SSL/TLS is always applied.
Additionally, FTAPI’s encryption technology enables fully end-to-end encrypted data transmission, ensuring that only the sender and recipient can read the data.
S/MIME and PGP are both secure email encryption methods, but they have not proven to be practical for everyday use. Their high administrative complexity and complicated onboarding make them unsuitable for dynamic business environments where contacts frequently change.
FTAPI has addressed these challenges with FTAPI SecuMails, a product designed to meet the needs of administrators and users alike. With FTAPI SecuMails, messages are instantly and securely encrypted – either directly within the email client after a simple installation of the Outlook add-in or via a browser using the FTAPI web interface. No technical expertise is required for use.
Yes, encrypted emails – including encrypted attachments – can be sent to multiple recipients, functional, and group mailboxes.
No, only one party (either the sender or recipient) needs an FTAPI licence to facilitate secure email communication.
