Bewertungsnotizen

Tresorit AG (Zurich, Pfingstweidstrasse 60b; CHE-349.825.210) is the enterprise-grade zero-knowledge end-to-end-encrypted cloud-storage product founded in 2011 by István Lám and Szilveszter Szebeni in Hungary and majority-acquired by Swiss Post (the Swiss state-owned postal operator) in 2021; Swiss Post remains the majority shareholder, and the about page describes Tresorit as part of Swiss Post's digital business services, so the company sits under Swiss state-anchored ownership (a stronger reading that Swiss Post is now the sole shareholder is not confirmable from a primary source, and 2021 coverage has the founders retaining a minority); ISO/IEC 27001:2022 certified by TÜV Rheinland, GDPR + HIPAA + ITAR + FINRA + CCPA + CJIS + DORA + NIS2 + TISAX coverage, customer-selectable Swiss or EU data residency, contracts under Swiss law / Swiss Federal Act on Data Protection. The verified sub-processor list (2026-06) shows Tresorit's primary hosting is Microsoft Azure (a US-owned hyperscaler), which raises CLOUD Act exposure to material on a structural reading; in practice the zero-knowledge end-to-end encryption means Azure stores only ciphertext and Tresorit holds no keys, so compelled disclosure yields no readable content. State-anchored Swiss (Swiss Post) ownership, ISO/IEC 27001:2022 certified by TÜV Rheinland; since the May 2026 audit the Data Processing Addendum is published at a public, login-free URL linked from tresorit.com/legal, closing the documentation gap that previously capped this listing.

Über Tresorit

Tresorit is the enterprise zero-knowledge end-to-end-encrypted cloud-storage product operated by Tresorit AG at Pfingstweidstrasse 60b, 8005 Zurich, Switzerland (CHE-349.825.210), with offices also in Budapest, Hungary and Munich, Germany. Founded in 2011 by Hungarian engineers István Lám and Szilveszter Szebeni, the company built its reputation around mathematically-provable client-side encryption: every file, file name, and metadata is encrypted on the user device before upload, so neither Tresorit nor any data-centre operator can access plaintext customer content. The company serves 11,000+ organisations with 4.9 / 4.5 G2 / Capterra ratings.

For an EU-sovereignty audit Tresorit's ownership story is unusually strong. In July 2021 Swiss Post (the Swiss state-owned postal and digital-services operator) acquired a majority stake, and the about page now describes Tresorit as part of Swiss Post's digital business services under the Swiss Post Digital name. Majority ownership is confirmed; a stronger claim that Swiss Post is now the sole shareholder could not be confirmed against a primary source, and 2021 coverage has the founders retaining a minority. This pushes the directory's other (Switzerland) classification into the highest end of that tier: Swiss jurisdiction with state-owned parent is structurally as close to "sovereign" as a vendor can credibly claim. The compliance footprint matches: ISO/IEC 27001:2022 certified by TÜV Rheinland (covering sales, development, maintenance, and support of E2E-encrypted cloud services), plus alignment with GDPR, HIPAA, ITAR, FINRA, CCPA, CJIS, DORA, NIS2, and TISAX, an unusually broad regulated-industry coverage including US healthcare (HIPAA), US defence-export controls (ITAR), US financial markets (FINRA), and US criminal-justice systems (CJIS) for the rare global customers who need that combination on top of a Swiss-jurisdiction base. Customer-selectable Swiss or EU data residency, contracts under Swiss law and the Swiss Federal Act on Data Protection.

Pricing in EUR: the personal ladder was renamed during 2026 and is now Personal Lite (50 GB), Personal Essential (1 TB) and Personal Pro (4 TB), with a monthly or yearly toggle advertising 20 percent off annual billing. The older Personal Plus tier no longer exists, and the amounts now render client-side, so the pricing page is the figure to budget against. Business plans start in the €14-30/user/month range across SecureCloud and Engage tiers; Enterprise is negotiated. Best fit: regulated enterprises (legal, financial-services, healthcare, defence), Swiss public-sector buyers, journalists and NGOs, and any organisation needing a Dropbox / Box / OneDrive replacement with mathematically-provable zero-knowledge encryption from a state-anchored Swiss vendor. Together with Proton Drive, Tresorit forms the directory's Swiss-encrypted file-sharing dual-pick; Proton wins on consumer / freemium and ecosystem breadth (Mail/VPN/Pass/Calendar/Docs), Tresorit wins on enterprise compliance breadth and the unique Swiss-Post state-owned governance.
