Legal entity from the vendor's own terms. LEI, registered country and parent company from the Global LEI Index (GLEIF); ownership is left empty where GLEIF names no parent. The CLOUD Act row is arithmetic over those countries, not an assessment of risk.

The count outside the EEA is arithmetic over the country column, not a judgement about lawfulness. A transfer outside the EEA can be perfectly lawful; whether this one is depends on your use, not on the vendor.

Processing terms

From the vendor's data processing agreement · read 2026-10-09 · proton.me

TermWhat the agreement says
Transfer mechanismSCC (module not stated)
Transfer mechanismSwiss FADP clauses
Transfer mechanismother
Notice of new subprocessorsSubprocessor list in Privacy Policy may be updated; customer informed via the Privacy Policy notification process (no period stated)
Breach notificationwithout delay
AuditInformation on request; audits/inspections by Company or its mandated auditor, max once per calendar year (except after a breach or regulator instruction), 60 days' prior written notice, during business hours, scope agreed in advance, NDA may be required

Terms as the agreement states them. Where it is silent on a term, there is no row; that is not a statement that the vendor does not offer it.

SOC 2 Type II · SOC2T2Claimed—proton.me2026-10-08

Claimed means the vendor asserts the scheme on its own page and offers nothing further. Available on request means the report or certificate exists but sits behind a request, a login or an NDA. Neither is a certificate we have seen. That is a distinction an auditor makes, so we make it too.

Official registers

Global LEI Index (GLEIF)Proton AG · Proton AGISSUEDCH2027-01-072026-10-09

What the authority publishes, not what the vendor claims. An entry covers the offering it names and nothing else: a FedRAMP authorisation for a government edition says nothing about the commercial service. No entry is not a finding about security - most vendors never apply - and an entry filed under a name not listed above would not have been found.
