Sealed against breach
Hackers who take the database take ciphertext. There is no master key on any server to find — so there is nothing to unlock, nothing to ransom, nothing to sell.
Zero-Knowledge Business Software
Your data stays yours.
Sealed against breach, leak and insider access.
We build business software on one rule: the people who run the servers can never read what is on them. Not hackers. Not admins. Not even us.
- No master key
- No back door
- No plaintext server-side
- Privately hostable — on your own infrastructure
The claim
Steal our servers, and you have stolen nothing.
Three ways confidential data dies. One architecture that survives all three.
Sealed against leak
Nothing readable exists on the server, so nothing readable can leak — not through a misconfigured bucket, not through a database dump, not through a careless export.
Sealed against insiders
No administrator, no DBA, no vendor — not even Zeromatics — can open your records. Access comes from cryptographic keys you control, not from job titles.
How it works
It locks before it leaves.
1
You enter it.
Your data is readable on your screen — and nowhere else.
2
It locks.
Encrypted on your device before it travels. The key is made from your password — and never leaves you.
3
Only the lock travels.
What the data server stores is already sealed. A breach reveals nothing, because nothing readable is there.
Even we can't open it.
This is zero-knowledge — and every product we make is built on it.
Products
One encrypted core. Five products.
The same zero-knowledge platform — configured for the professions where confidentiality is the job. Run it in the cloud, or have it hosted entirely on your own infrastructure.
Zeromatics Workspace
Teams & enterpriseAn encrypted drive and document workspace — with document workflow, e-signing and digital signatures built in. Access is granted by keys, not by trust in an administrator.
Explore WorkspaceZeroEMR
HealthcareElectronic medical records where the patient's data is sealed at the point of care. Clinics get a modern EMR; patients get real privacy.
Explore ZeroEMRZeromatics EOffice
GovernmentA secure e-office for government. Files, movements and approvals go digital — built for the way government actually works, with nothing readable on the server.
Explore EOfficeZeromatics Legal
Law firmsPractice management for law firms. Matters, parties, hearings, documents and deadlines — encrypted so that not even the vendor can see client work.
Explore LegalZeroMessage
Secure messagingMessaging for organisations where only the sender and the receiver can read a message. End-to-end, inside the same platform your documents live in.

Everything a modern team expects. Nothing a thief can use.
In every product
Private AI, built in
Ask questions across your matters, files and records — and get answers grounded in your own documents (RAG). The models are small language models hosted on your own infrastructure. Your documents never go to a public AI. Nothing leaves your control.
- RAG over your encrypted documents
- Privately hosted SLMs — on-premise or your cloud
- AI agents are grantees — access is given by you, like a colleague
In every product
Task management
Assign, track and complete work across teams — tasks, boards and deadlines come standard in every Zeromatics product.
Zeromatics Workspace
Document workflow & e-signing
Route documents for review and approval, collect e-signatures, and apply cryptographic digital signatures — built into Workspace as standard.
Why it matters
The headlines that shouldn't exist.
April 2026. Two countries, one month, one failure: the data sat readable on a server.
Land, courts & transport
April 2026 · UAE
Dubai's land registry, courts and transport authority breached in one campaign
A hostile group claimed an attack on the Dubai Land Department, Dubai Courts and the Roads and Transport Authority — around 149 terabytes reportedly exfiltrated, with claims of petabytes more destroyed. Property records, case files and citizen movement data: the administrative backbone of a city, taken from its servers.
With Zeromatics: 149 terabytes of exfiltrated ciphertext is 149 terabytes of nothing.

National identity
April 2026 · France
19 million citizens' ID records offered for sale
France's agency for passports, national IDs and driving licences confirmed a breach. Names, dates of birth, addresses and account data of up to a third of the population — up for sale on criminal forums within a day. The flaw behind it was so basic the attacker called it 'really stupid'.
With Zeromatics: the same flaw would have served the attacker 19 million sealed records — and no keys.
