<small>防護下列威脅：</small>

- [:material-bug-outline: 被動攻擊](basics/common-threats.md#security-and-privacy ""){.pg-orange}
- [:material-server-network: 服務提供商](basics/common-threats.md#privacy-from-service-providers ""){.pg-teal}

**許多雲端儲存提供商** 要求您完全信任他們不會查看您的檔案。 The alternatives listed below eliminate the need for trust by implementing secure end-to-end encryption.

如果這些替代方案不符合您的需求，建議您考慮使用其他雲端提供商的加密軟體，例如 [Cryptomator](encryption.md#cryptomator-cloud) 。 把 Cryptomator 結合在 **任一種** 雲服務商(包含這裡推薦的) 也是好方法，可減低某服務商原生客戶端加密漏洞之風險。

<summary>尋找 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
    - 該檢查評估了Tresorit 網頁用戶端、Android 應用程式、Windows 應用程式和相關基礎設施的安全性。
    - Computest 發現了兩個已解決的漏洞。
- [2019](https://tresorit.com/blog/ernst-young-review-verifies-tresorits-security-architecture): Penetration Testing by Ernst & Young.
    - 該檢測分析了 Tresorit 完整源代碼，並驗證了落實 Tresorit [白皮書](https://prodfrontendcdn.azureedge.net/202208011608/tresorit-encryption-whitepaper.pdf)中描述的概念。
    - 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 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.
