The standard of proof for the things you make.
asserro gives every product a tamper-proof identity — proven, stored, and yours to control. Starting with the one Europe is mandating first: the battery passport.
Three passports. Two vaults. Self-custody, maximum verifiability.
The passports run on one verification engine — proving a product is genuine across its whole life, from the workshop through every owner to the very end. The vaults are a separate layer: self-custody storage and access control, so the proof, keys and credentials stay yours to keep, recover and grant — held by you, never by us.

Two things sit beside the passports: the consoles where you actually run them — enrol, verify, export — and the vaults that store and control the proof, keys and credentials.
One identity, from cradle to cradle.
Created once and carried for life. Every stage adds a tamper-evident record; the final stages adapt to the product, and the loop closes when what remains returns to the beginning.
No longer optional.
Europe has made the product passport law, and the battery passport is the first hard deadline. The houses that move early own the standard — and turn a compliance cost into a mark of distinction. Beyond the EU, India, New Jersey and others are moving the same way.
The name
From the Latin asservō — to guard, to keep safe, to preserve. Each product joins a domain to that root.
The house
asserro began in 2021 as a single idea — protect what is genuine. As Europe turned that idea into law, it became a family: one verification engine, three products, and the vaults that hold them.
asserro is the marque for verifiable trust — one verification engine, three passports, and the vaults that keep them.
Or make it your own.
Run asserro under your own brand — as a product you sell to your customers on a revenue share, or as your group's own internal system. Same verification engine; your name on it.
