Security shouldn’t be complicated, so we’ve simplified it


We take security seriously

Two-factor authentication ensures that only intended recipients can access messages you send them. Several options are available when initiating a message for added flexibility. 

Transport Layer Security (TLS) secures the connection between you and the recipient. We use it so that one else can intercept your communications.

DMU - Security - Asymmetric

Asymmetric zero-knowledge encryption

Ensures that no unauthorized people can access your message. 

All your messages and/or attachments are stored asymmetrically encrypted in such a way (zero-knowledge encryption) that even Zivver cannot decrypt the information.

Your confidential communications remain truly confidential.


Safeguarding communications entails much more than security
