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.
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.
**Proton Drive** is an encrypted cloud storage provider from the popular encrypted email provider [Proton Mail](email.md#proton-mail).
The initial free storage is limited to 2GB, but with the completion of [certain steps](https://proton.me/support/more-free-storage-existing-users), additional storage can be obtained up to 5GB.
The Proton Drive web application has been independently audited by Securitum in [2021](https://proton.me/community/open-source), but the brand new mobile clients have not yet been publicly audited by a third party.
- 해당 검토에서는 Tresorit의 전체 소스 코드를 분석하여, Tresorit [백서](https://prodfrontendcdn.azureedge.net/202208011608/tresorit-encryption-whitepaper.pdf)에서 설명한 개념과 구현이 일치하는지 검증했습니다.
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, and view their photos, videos, documents, etc. Peergos secures your files with quantum-resistant E2EE and ensures all data about your files remains private.
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}.
Peergos is primarily a web app, but you can self-host the server either as a local cache for your remote Peergos account, or as a standalone storage server which negates the need to register for a remote account and subscription. The Peergos server is a `.jar` file, which means the Java 17+ Runtime Environment ([OpenJDK download](https://azul.com/downloads)) should be installed on your machine to get it working.
Running a local version of Peergos alongside a registered account on their paid, hosted service allows you to access your Peergos storage without any reliance on DNS or TLS certificate authorities, and keep a copy of your data backed up to their cloud. The user experience should be the same whether you run their desktop server or just use their hosted web interface.
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.
