Why secure e-mail?

Prevent a data breach

According to research from the EU data protection authority, most data leaks occur by sending personal data to the wrong recipient. Before you know it, privacy-sensitive data of your organization and / or clients are out there, available for everybody to see. You can easily prevent this by protecting your email environment.

More about safe mailing

Comply with laws and regulations under the general regulation of personal data (GDPR)

The European Privacy Act, the GDPR, obliges all countries within the EU to secure personal data in the same secure manner. For companies, this means that files can only be send securely if the e-mail environment is modified accordingly.
