VPNInfobaseProton VPN is run by a Swiss company whose primary shareholder is a non-profit foundation, has had five annual no-logs audits from the same firm, and says every app is open source. The one thing we could not read is its price: the pricing page is built in the browser.
Ownership and jurisdiction
Proton’s about page says its services are operated by Proton AG, “a Swiss corporation whose primary shareholder is the non-profit Proton Foundation based in Geneva”, and that it has no venture capital investors. That is a vendor statement, not a filing, and “primary shareholder” does not tell you the size of the holding. Proton’s terms say Swiss law governs for users outside the US. The ownership table shows the alternatives: Kape-owned, founder-owned, or a merger with unstated terms.
Two kinds of audit, kept apart
Proton’s no-logs audit page says Securitum has audited Proton VPN for five consecutive years (2022 to 2026, latest reported June 2026), publishes the full reports, and that the 2026 report found no evidence in the examined infrastructure of logged browsing activity, DNS queries, destinations, traffic contents or user-identifiable connection metadata. Those are the no-logs audits. The register did not capture the report links, so open them from Proton’s page.
App security is a separate matter. Proton’s open-source post, updated 1 December 2025, links audits of its client apps by an independent security researcher it contracted. A no-logs audit does not test apps, and an app test does not test logging: the audit tracker sorts every provider this way.
Open source, as stated
The same post says the Android, iOS and iPadOS, macOS, Windows and browser-extension apps are open source, and “all Proton apps that are out of beta” are. That is a stronger statement than the register holds for most providers (the register records four providers stating it: Proton VPN, PIA, IVPN and Windscribe). Open code lets outsiders read the client; it says nothing about the servers.
Price: not read
Proton’s pricing page loads its prices after the page opens, so a static read shows only placeholders. The register therefore holds no Proton price, and we do not quote one. The support and plan pages we opened carry no VPN price either; press articles quote figures, which we do not repeat because we could not read them on a Proton page. It does list a free tier. Refund terms in Proton’s terms are 30 days from first purchase, once per user, on direct purchases only. Compare the providers we could read on the renewal price table.
Who it fits, going by the register fields
- Pick it if you want an owner that is not a VPN group or an individual, audits with public reports, open-source apps and a free tier to try first.
- Look at others if you need a price you can check in advance (this page cannot give one), or a flat, anonymous-payment model, which Mullvad states.
