IncaMail Encrypt confidential emails
Why should I use IncaMail? How secure communication works
With IncaMail, you can securely send confidential emails in compliance with DSG and GDPR.
Every day, more businesses and individuals are exchanging contracts, invoices, and payslips via email. While it's quick and efficient, it also comes with risks. If your data isn’t encrypted, cybercriminals can easily intercept and manipulate it. Standard emails offer little protection against data loss, tampering, or fraud, putting both your privacy and compliance at risk. In fact, unencrypted emails don't meet the strict security standards of the Swiss Federal Data Protection Act (DSG) and the European General Data Protection Regulation (GDPR). Worse yet, failing to comply could result in hefty penalties for senders.
