The name “INCA” is based on the four security features of IncaMail:
Integrity (change protection)
Swiss Post ensures that your e-mails remain complete and unchanged while being sent via the Internet.
Non-repudiability
IncaMail detects the sending and receipt of your e-mails. For the “Registered” dispatch type, you will receive as proof a digitally signed receipt with a time stamp.
Confidentiality (access protection)
IncaMail encrypts your e-mails according to a patented process. The process guarantees that third parties will not be able to view or falsify your data during sending.
Authentication (protection against falsification)
IncaMail checks senders and recipients of encrypted e-mails and assigns them a trust level of up to three stars. As a minimum, the e-mail address must be verified.
