Analysis
OVERVIEW
Vault items and vault metadata are end-to-end encrypted. The apps are open source, Cure53 has audited them, and the product combines passwords, passkeys, aliases, and sharing.
LIMITS
A Proton account still creates account and activity metadata. Alias addresses must remain readable for mail forwarding, and paid plans add a payment trail.
USEFUL FOR
Password and passkey storage with built-in email aliases across browser, desktop, and mobile apps.

Ownership chain
Who owns the operator, read from the public register. Each step says what kind of evidence it rests on: a registry record can be checked, a company statement cannot.
- OPERATORProton AGCHE-354.686.492 · Switzerland
- PRINCIPAL SHAREHOLDERFondation ProtonCHE-418.863.304 · SwitzerlandCOMPANY STATEMENT
As Proton's primary shareholder, the foundation exercises its control to ensure that Proton does not deviate from our mission. No change of control of Proton can occur without the consent of the Foundation.
Both entities are registry-confirmed, but the shareholding between them is not. Swiss law does not require a company to publish its shareholders, so this edge rests on Proton's own account of its governance and cannot be checked against Zefix.
Proton Foundation governance page ↗
The chain stops here because the register stops, not because the top was reached. Swiss and Swedish companies do not publish their shareholders, and a Czech joint-stock company does not list its own. Nothing above the last step should be assumed either way.
SAME OPERATOR
Proton AG also runs 3 other services shown here. Comparing them compares products, not independent companies.
WHAT IT USED TO BE
- Proton Technologies AGrenamed 2021-09-30REGISTRY RECORD
Renamed by the same legal person, not a new company. The Swiss Official Gazette entry of 18.10.2021 reads 'Nouvelle raison sociale: Proton AG', with the statutes modified on 30.09.2021. The UID is unchanged either side of the rename, which is what proves it is one entity.
- ProtonVPN AGabsorbed 2020-06-30REGISTRY RECORD
Recorded on both sides of the register: Proton AG lists ProtonVPN AG under companies taken over, and the ProtonVPN AG record names Proton AG as the entity that took it over. The VPN product has had no separate company since.
