End-to-end, properly
Keys live on the sender's and receiver's devices — nowhere else. The server relays sealed envelopes it cannot open.
Secure messaging
ZeroMessage
Messages only two people can read.
End-to-end encrypted messaging for organisations — sovereign, governable, and living inside the same platform your documents do.
Like every Zeromatics product:
Sealed against breach
Sealed against leak
Sealed against insider access
Privately hostable
What's inside
Signal-grade. Organisation-shaped.
Built for organisations
Directories, groups, roles and onboarding — organisational control without organisational access to content.
Documents, in the flow
Share encrypted files from Workspace straight into a conversation — access granted by key, never by copy.
Sovereign hosting
Run it on your own infrastructure or your national cloud. The cryptography does not care who hosts it — and neither does your privacy.
Nothing to mine
We cannot read messages, so we cannot mine them, profile them, or hand them over. There is nothing to hand over.
Desktop & mobile
Native apps where your people work — with the same sealed envelope on every platform.
From the platform
And everything the platform gives every product.
Task management
Assign, track and complete work across teams — tasks, boards and deadlines come standard.
Private AI (RAG)
Answers grounded in your own documents, generated by small language models hosted on your infrastructure. Nothing leaves your control.
Give your organisation a channel nobody taps.
Watch your own data turn to ciphertext before it leaves the browser. The demo takes two minutes.
