E-mail security
Send secure and recognized e-mails

Anchor Navigation

Ordinary e-mails are poorly protected. They are as easy to read as a postcard. For this reason, companies need a reliable solution for exchanging sensitive information via e-mail. IncaMail meets rigorous requirements and is officially recognized by the Swiss Confederation as a secure electronic delivery platform.

What are the risks?

E-mails often contain sensitive and confidential data. This could include contracts, customer data or strategy papers. What happens if they fall into the wrong hands? You may be liable to prosecution. You could face serious fines, and your image could be damaged. All personal data relating to an identified or identifiable person must be protected, including their first and last names. This is stipulated in the Federal Act on Data Protection (FADP) and the European General Data Protection Regulation (GDPR).
