Proof,
not promises.
In a world where anything can be faked, cryptographically prove what's real, from a single image to an entire organisation's conduct. We give you back the keys to your data, so nobody, not even mintBlue, can touch what's yours.

One way to
make it provable.
Four parts of one infrastructure, each turning trust into something you check.
Signed where it's born.
Every change is written as a signed event the moment it happens, so a later edit breaks the proof. Field-level encryption seals it, and you reveal one fact without exposing the rest.
Rules that enforce themselves.
Hand an organisation your data and verify, cryptographically, that they followed the rules. Compliance you can verify, not compliance you're promised.
Prove the claim, not the data.
eIDAS-aligned identity proves a statement is true without revealing what's behind it. Know who you are dealing with, and what they are entitled to, before any data moves.
An audit log that can't be rewritten.
A continuous, tamper-evident record of every action, replayable from the first event. No central database anyone has to trust. An audit trail that still holds years later.
Where the proof already runs.
Trusted by governments, enterprises and non-profits to make data verifiable without giving up ownership.
Where proof matters most.
For data that has to cross organisational borders, and stay trusted there.
Built in Europe, for Europe
Most of the Western world's data sits on American infrastructure, exposed to CLOUD Act subpoenas and foreign acquisition risk. Trading an American cloud for a European one only moves that dependency. mintBlue removes it: sovereign infrastructure where you control every deployment decision and every encryption key.
Built on Open Standards

Start with proof
Check it for yourself.
A 30-minute assessment: we map your stakeholders and the bottlenecks between them, and show where proof replaces a promise.
