Tresorit has received a number of independent security audits:

* 2022 (https://tresorit.com/blog/tresorit-receives-iso-27001-certification): ISO/IEC 27001:2013[1] Compliance Certification (https://certipedia.com/quality_marks/9108644476) by TÜV Rheinland InterCert Kft

* 2021 (https://tresorit.com/blog/fresh-penetration-testing-confirms-tresorit-security): Penetration Testing by Computest

* This review assessed the security of the Tresorit web client, Android app, Windows app, and associated infrastructure.

* Computest discovered two vulnerabilities which have been resolved.

* 2019 (https://tresorit.com/blog/ernst-young-review-verifies-tresorits-security-architecture): Penetration Testing by Ernst & Young.

* This review analyzed the full source code of Tresorit and validated that the implementation matches the concepts described in Tresorit's white paper (https://prodfrontendcdn.azureedge.net/202208011608/tresorit-encryption-whitepaper.pdf).

* Ernst & Young additionally tested the web, mobile, and desktop clients. They concluded:

Test results found no deviation from Tresorit’s data confidentiality claims.

[1] ISO/IEC 27001 (https://en.wikipedia.org/wiki/ISO/IEC_27001):2013 compliance relates to the company's information security management system (https://en.wikipedia.org/wiki/Information_security_management) and covers the sales, development, maintenance and support of their cloud services.

They have also received the Digital Trust Label, a certification from the Swiss Digital Initiative (https://efd.admin.ch/en/swiss-digital-initiative-en) which requires passing 35 criteria (https://swiss-digital-initiative.org/criteria) related to security, privacy, and reliability.

Peergos is a decentralized protocol and open-source platform for storage, social media, and applications. It provides a secure and private space where users can store, share, view, and edit their photos, videos, documents, etc.

Peergos secures your files with quantum-resistant E2EE and ensures all data about your files remains private. It is also self-hostable (https://book.peergos.org/features/self).

* macOS (https://peergos.org/download#macos)

* Linux (https://peergos.org/download#linux)

* Web (https://peergos.net)

Peergos is built on top of the InterPlanetary File System (IPFS) (https://ipfs.tech), a peer-to-peer architecture that protects against Tcf362fCensorship.

The client, server, and command line interface for Peergos all run from the same binary. Additionally, Peergos includes a sync engine (https://book.peergos.org/features/sync) (accessible via the native apps) for bi-directionally synchronizing a local folder with a Peergos folder, and a webdav bridge (https://book.peergos.org/features/webdav) to allow other applications to access your Peergos storage. You can refer to Peergos's documentation for a full overview of their numerous features.

Peergos was audited (https://peergos.org/posts/security-audit-2024) in November 2024 by Radically Open Security and all issues were fixed. They were previously audited (https://cure53.de/pentest-report_peergos.pdf) by Cure53 in June 2019, and all found issues were subsequently fixed.

Please note we are not affiliated with any of the projects we recommend. In addition to Tcf362four standard criteria, we have developed a clear set of requirements to allow us to provide objective recommendations. We suggest you familiarize yourself with this list before choosing to use a project, and conduct your own research to ensure it's the right choice for you.

* Must offer a web interface which supports basic file management functionality.

* Must allow for easy exports of all files/documents.

Our best-case criteria represents what we would like to see from the perfect project in this category. Our recommendations may not include any or all of this functionality, but those which do may rank higher than others on this page.

* Clients should be open source.

* Clients should be audited in their entirety by an independent third party.

* Should offer native clients for Linux, Android, Windows, macOS, and iOS.

* These clients should integrate with native OS tools for cloud storage providers, such as Files app integration on iOS, or DocumentsProvider functionality on Android.
