<small>Protects against the following threat(s):</small>

Many **cloud storage providers** require your full trust that they will not look at your files. The alternatives listed below eliminate the need for trust by implementing secure end-to-end encryption.

이러한 대안들이 여러분의 요구에 맞지 않는 경우, 다른 클라우드 제공 업체를 [Cryptomator](encryption.md#cryptomator-cloud) 등의 암호화 소프트웨어와 함께 사용할 것을 권장합니다. **어떤** 클라우드 제공 업체든(본 목록 포함), Cryptomator를 함께 사용함으로써 제공 업체의 기본 클라이언트에서 발생할 수 있는 암호화 결함 위험성을 낮출 수 있습니다.

<summary>Looking for Nextcloud?</summary>

For more technical readers, Nextcloud is [still a recommended tool](self-hosting/file-management.md#nextcloud) for self-hosting a file management suite, however we do not recommend third-party Nextcloud storage providers at the moment, because we do [not recommend](https://discuss.privacyguides.net/t/dont-recommend-nextcloud-e2ee/10352/29) Nextcloud's built-in E2EE functionality for home users.

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
    - 해당 검토에서는 Tresorit 웹 클라이언트, Android/Windows 앱 및 관련 인프라 보안을 평가했습니다.
    - Computest는 취약점을 2개 발견했으며, 이 취약점은 해결되었습니다.
- [2019](https://tresorit.com/blog/ernst-young-review-verifies-tresorits-security-architecture): Penetration Testing by Ernst & Young.
    - 해당 검토에서는 Tresorit의 전체 소스 코드를 분석하여, Tresorit [백서](https://prodfrontendcdn.azureedge.net/202208011608/tresorit-encryption-whitepaper.pdf)에서 설명한 개념과 구현이 일치하는지 검증했습니다.
    - Ernst & Young additionally tested the web, mobile, and desktop clients. They concluded:

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

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

<div class="admonition recommendation" markdown>

![Peergos logo](assets/img/cloud/peergos.svg){ align=right }

</div>

Peergos is built on top of the [InterPlanetary File System (IPFS)](https://ipfs.tech), a peer-to-peer architecture that protects against [:material-close-outline: Censorship](basics/common-threats.md#avoiding-censorship ""){.pg-blue-gray}.

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.
