| The Best Private and Secure Cloud Storage Providers - Privacy Guides | Felhőtárhely | material/file-cloud | Many cloud storage providers require your trust that they will not look at your files. These are private alternatives! | cloud.webp |
Protects against the following threat(s):
- :material-bug-outline: Passive Attacks{.pg-orange}
- :material-server-network: Service Providers{.pg-teal}
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 E2EE.
If these alternatives do not fit your needs, we suggest you look into using encryption software like Cryptomator with another cloud provider. Using Cryptomator in conjunction with any cloud provider (including these) may be a good idea to reduce the risk of encryption flaws in a provider's native clients.
Looking for Nextcloud?
Nextcloud is still a recommended tool 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 Nextcloud's built-in E2EE functionality for home users.
Proton Drive

The Proton Drive web application has been independently audited by Securitum in 2021.
Proton Drive's brand new mobile clients have not yet been publicly audited by a third party.

Tresorit has received a number of independent security audits:
- 2022: ISO/IEC 27001:20131 Compliance Certification by TÜV Rheinland InterCert Kft
- 2021: 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: 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.
- Ernst & Young additionally tested the web, mobile, and desktop clients: "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 which requires passing 35 criteria related to security, privacy, and reliability.
Peergos
{ align=right }
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 end-to-end encryption and ensures all data about your files remains private.
:octicons-home-16: Homepage{ .md-button .md-button--primary } :octicons-eye-16:{ .card-link title="Privacy Policy" } :octicons-info-16:{ .card-link title="Documentation" } :octicons-code-16:{ .card-link title="Source Code" } :octicons-heart-16:{ .card-link title="Contribute" }
Peergos is built on top of the InterPlanetary File System (IPFS), a peer-to-peer architecture that protects against :material-close-outline: 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) 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 in November 2024 by Radically Open Security and all issues were fixed. They were previously audited by Cure53 in June 2019, and all found issues were subsequently fixed.
