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 products. Two vaults. One verifiable identity.
One engine proves a product is genuine, stores that proof, and lets you control exactly who can see, transfer or inherit it — from the workshop, through every owner, to the very end.

Verifiable proof is only useful if you can keep it, recover it, and decide who reaches it. That is the .app layer — the vault and access control beneath everything asserro proves.
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 asservāre — 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 corporate marque — part of asserro.com, and the corporate sister of noklock, our personal vault.
