What is your risk?

You are not looking for a "proof infrastructure". You are looking for an answer to a specific constraint.

CIO / CISO

Secure without opening your systems

Refuse the intrusive access of auditors and GRC solutions that widen the attack surface.

  • A discreet appliance, installed on your premises
  • Your data stays on your servers, encrypted
  • Only a fingerprint circulates to prove integrity

02 / Why 0DATA

Three fears. Three proofs.

01
Facing the NIS2 fine

Your compliance is no longer a declaration; it is verifiable proof, continuously traced.

02
Facing the insurer who refuses to pay

In the event of a claim, the sealed chronology documents the facts in a verifiable way.

03
Facing the auditor

Inventory, traceability, history — sealed, timestamped, exportable in one click.

03 / Protocol

How it works

01

We measure, on your site

Your obligations measured continuously — by the on-site Box, or pushed by your systems. Sealing every 15 minutes. No inbound connection.

02

Every measurement is sealed

Chained fingerprint + anchoring on a public registry · built-in qualified eIDAS timestamping. Any tampering is detectable by a third party.

03

The auditor verifies

A third party checks integrity directly on the public registry. You no longer send an Excel file: you send a chain of proof.

04 / Catalogue

18 verticals. One single proof.

Each vertical measures an obligation continuously, seals it and makes it verifiable. When a counterparty demands the proof, it can bear the cost.

Sector pages: Finance & Insurance · Energy & Building · Healthcare & Life Sciences
05 / Physical layer

Proof, from the object itself.

A secure chip, integrated into the object, the batch or the person, seals the proof at the source — offline, even before the network exists.

Access card

  • Passwordless login (FIDO2)
  • Key on chip, non-extractable
  • Hardware wallet (chip)

Anti-counterfeit label

  • Unique challenge per tap
  • Verifiable offline
  • Cap, packaging, textile

Embedded module

  • Machine identity (SMD)
  • Production signature
  • Battery, meter, line

Field tag

  • Offline sealing (IP68)
  • Hash at capture
  • Anchoring on network return

Technical proof element · built-in qualified eIDAS timestamping · sealing from 0,20 €.

06 / Products

The Box, on your site.

A pocket-book-sized appliance, plugged in at your premises, timestamps every measurement and publishes the proof. Silent, low-power, zero maintenance.

08 / FAQ

What people ask us.

Does this replace my auditor?

No. 0DATA produces the technical proof element — your auditor, your counsel or the regulator makes the judgment.

Do my data leave my site?

In Box mode (on-prem), no: only the fingerprint is sealed and anchored, never the data.

What if 0DATA disappears?

The chain remains verifiable on public registries. The proof outlives you.

Is it admissible?

It is technical proof of integrity and prior existence. Your counsel will make the judgment.
