End to end encryption cloud storage isn't just a fancy tech term—it's your last line of defense against data breaches and privacy violations. While all cloud providers claim to keep your files safe, the truth is far more complex. Not all encrypted storage solutions offer the same level of protection. In fact, only zero-knowledge encryption ensures your files remain truly private from everyone, including the service provider itself. This means that not even the cloud storage company knows what you're storing or has access to your passwords. We've tested dozens of cloud storage platforms to find the most secure options available in 2025. Although most services utilize AES-256 encryption for files at rest and TLS/SSL protection during transfers, the best encrypted cloud storage solutions go beyond that with client-side encryption that puts you in complete control. From our extensive testing, Sync.com stands out with its perfect balance of affordable pricing, robust cloud features, and excellent security protocols. However, other services like pCloud—based in Switzerland with its stringent privacy laws—and Internxt with its cutting-edge post-quantum encryption algorithm also deserve serious consideration for secure data storage. In this guide, we'll walk you through the 7 most secure cloud storage providers that truly protect your sensitive information.

The file request feature lets you send upload links so recipients can securely send documents to your account without requiring shared folder access.
Moreover, the mobile apps offer automatic photo and video uploading capabilities, though currently there's no way to exclude specific folders from this process.
Sync.com encryption and privacy
Security serves as the cornerstone of Sync.com's offering. The service employs end-to-end encryption, meaning your files are encrypted before upload and only you possess the decryption keys. This zero-knowledge approach ensures that not even Sync.com can access your data.
From a technical perspective, Sync.com utilizes AES-256-GCM encryption secured with RSA-2048 private keys. Your password never leaves your device, as it undergoes one-way hashing using Bcrypt and is never stored on Sync.com's servers. PBKDF2 key stretching with high iteration counts helps strengthen weak passwords against brute force attacks.
Despite being based in Canada (a Five Eyes member country), the end-to-end encryption means that even if compelled by law enforcement, Sync.com cannot access your encrypted files. The web portal is open-source and uses modern JavaScript cryptography libraries, though desktop and mobile apps remain closed-source.
For additional protection, Sync.com recommends enabling two-factor authentication and local drive encryption through BitLocker (Windows) or FileVault (Mac).

One distinctive aspect of pCloud is its server location options. New users can choose between European Union or United States data centers, giving you control over where your data physically resides. This feature is particularly valuable for users concerned about regional privacy regulations.
Additionally, pCloud implements a 30-day trash history on paid plans, enabling you to restore previous versions of files or recover accidentally deleted content. For those needing extended protection, an optional Extended File History feature extends this recovery window to 360 days.
pCloud encryption and privacy
pCloud employs a dual-layer approach to security. By default, all files receive TLS/SSL encryption during transfer and are stored with AES-256 encryption on pCloud's servers. Your data is distributed across at least three server locations for redundancy and protection.
What truly distinguishes pCloud is its optional "Crypto" feature that provides genuine end-to-end encryption. With pCloud Crypto, your most sensitive files are encrypted on your device before upload, creating a zero-knowledge environment where not even pCloud can access your data. This client-side encryption uses 4096-bit RSA for private keys and 256-bit AES for per-file and per-folder keys.
Notably, pCloud is the first major provider to offer both encrypted and non-encrypted folders in the same account. This hybrid approach allows you to selectively encrypt sensitive files while maintaining full functionality for standard files. Encrypted files remain inaccessible to anyone without your Crypto Pass—even if your device is stolen.
To demonstrate its security efficacy, pCloud previously challenged hackers worldwide with a $100,000 bounty to break their encryption. After six months, 2,860 participants failed to breach the system.

Tresorit key features
Tresorit's file management system operates through "tresors" (secure encrypted folders) that can be synced across multiple devices. Users can transform any local folder into a tresor without changing their existing folder structure. The platform provides selective sync functionality, allowing you to choose which specific subfolders will sync to your device—a helpful feature for managing storage space.
Accordingly, file sharing comes in two primary forms. You can invite collaborators to access entire tresors, requiring them to create a Tresorit account. Alternatively, you can generate secure links to share specific files or folders, accessible even to those without Tresorit accounts. For business users, granular permission settings enable you to designate collaborators as managers, editors, or viewers, with corresponding access rights.
The mobile applications offer intuitive interfaces with passcode or biometric protection and automatic photo/video upload capabilities. Additionally, business users gain access to e-signature tools through SwissSign for legally valid contracts and a project management tool called Engage Rooms for team collaboration.
Tresorit encryption and privacy
Security serves as Tresorit's cornerstone, employing end-to-end encryption with a zero-knowledge approach. All files and metadata receive protection using randomly generated encryption keys that never travel in unencrypted form. Data is secured with AES-256 encryption, and new keys are generated each time a file changes.
Distinctively, Tresorit applies a Message Authentication Code (MAC) to each file's content, with the code known only to your device and those you've shared with—but not stored by Tresorit itself. This ensures files cannot be modified without your knowledge, even if their system was compromised. Due to this robust security architecture, not even Tresorit staff can access your files.
For businesses requiring maximum compliance, Tresorit offers customizable server locations to meet data residency requirements and maintains certification for compliance with ISO 27001:2022.
Tresorit pricing
Tresorit offers multiple pricing tiers for both individuals and businesses:

Canadian-based Sync.com focuses primarily on delivering a cloud storage experience with robust security features and privacy protections. Since its founding in 2011, the company has positioned itself as a zero-knowledge storage provider that keeps your data genuinely private.
Sync.com key features
Sync.com offers comprehensive file syncing capabilities that work across Windows, macOS, iOS, and Android devices. One of the standout features is the Sync Vault, which enables online-only backup without syncing files across all your devices. This preserves local storage space on your machines yet maintains quick access to your cloud files.
File versioning is another notable capability, allowing you to recover previous versions of files if they become corrupted or infected by ransomware. Free users can retrieve files up to 30 days old, whereas Personal Pro accounts have no time restrictions.
Sharing options are both flexible and secure. You can create password-protected links to share individual files, which can be revoked at any time. Pro users gain additional controls like expiry dates, download limits, document previews, and email notifications for file activity. The file request feature lets you send upload links so recipients can securely send documents to your account without requiring shared folder access.
Moreover, the mobile apps offer automatic photo and video uploading capabilities, though currently there's no way to exclude specific folders from this process.
Sync.com encryption and privacy
Security serves as the cornerstone of Sync.com's offering. The service employs end-to-end encryption, meaning your files are encrypted before upload and only you possess the decryption keys. This zero-knowledge approach ensures that not even Sync.com can access your data.
From a technical perspective, Sync.com utilizes AES-256-GCM encryption secured with RSA-2048 private keys. Your password never leaves your device, as it undergoes one-way hashing using Bcrypt and is never stored on Sync.com's servers. PBKDF2 key stretching with high iteration counts helps strengthen weak passwords against brute force attacks.
Despite being based in Canada (a Five Eyes member country), the end-to-end encryption means that even if compelled by law enforcement, Sync.com cannot access your encrypted files. The web portal is open-source and uses modern JavaScript cryptography libraries, though desktop and mobile apps remain closed-source.
For additional protection, Sync.com recommends enabling two-factor authentication and local drive encryption through BitLocker (Windows) or FileVault (Mac).
Sync.com pricing
Sync.com offers various plans to accommodate different storage needs:

pCloud provides seamless file synchronization across all major platforms, including Windows, macOS, iOS, Android, and even Linux—a rarity among cloud storage providers. The service creates a virtual drive on your computer, allowing you to access cloud files without consuming local storage space.
File sharing capabilities are robust, featuring password-protected links and customizable options. You can personalize shared links with your own title, image, headline, and description. For media enthusiasts, pCloud includes built-in players for streaming photos, videos, and audio directly from storage without downloading.
One distinctive aspect of pCloud is its server location options. New users can choose between European Union or United States data centers, giving you control over where your data physically resides. This feature is particularly valuable for users concerned about regional privacy regulations.
Additionally, pCloud implements a 30-day trash history on paid plans, enabling you to restore previous versions of files or recover accidentally deleted content. For those needing extended protection, an optional Extended File History feature extends this recovery window to 360 days.
pCloud encryption and privacy
pCloud employs a dual-layer approach to security. By default, all files receive TLS/SSL encryption during transfer and are stored with AES-256 encryption on pCloud's servers. Your data is distributed across at least three server locations for redundancy and protection.
What truly distinguishes pCloud is its optional "Crypto" feature that provides genuine end-to-end encryption. With pCloud Crypto, your most sensitive files are encrypted on your device before upload, creating a zero-knowledge environment where not even pCloud can access your data. This client-side encryption uses 4096-bit RSA for private keys and 256-bit AES for per-file and per-folder keys.
Notably, pCloud is the first major provider to offer both encrypted and non-encrypted folders in the same account. This hybrid approach allows you to selectively encrypt sensitive files while maintaining full functionality for standard files. Encrypted files remain inaccessible to anyone without your Crypto Pass—even if your device is stolen.
To demonstrate its security efficacy, pCloud previously challenged hackers worldwide with a $100,000 bounty to break their encryption. After six months, 2,860 participants failed to breach the system.

Founded in 2011, Tresorit delivers cloud storage with a strong focus on security and privacy protections. Based in Switzerland, this provider leverages strict Swiss privacy laws to offer a highly secure storage solution primarily targeted at businesses and privacy-conscious individuals.
Tresorit key features
Tresorit's file management system operates through "tresors" (secure encrypted folders) that can be synced across multiple devices. Users can transform any local folder into a tresor without changing their existing folder structure. The platform provides selective sync functionality, allowing you to choose which specific subfolders will sync to your device—a helpful feature for managing storage space.
Accordingly, file sharing comes in two primary forms. You can invite collaborators to access entire tresors, requiring them to create a Tresorit account. Alternatively, you can generate secure links to share specific files or folders, accessible even to those without Tresorit accounts. For business users, granular permission settings enable you to designate collaborators as managers, editors, or viewers, with corresponding access rights.
The mobile applications offer intuitive interfaces with passcode or biometric protection and automatic photo/video upload capabilities. Additionally, business users gain access to e-signature tools through SwissSign for legally valid contracts and a project management tool called Engage Rooms for team collaboration.
Tresorit encryption and privacy
Security serves as Tresorit's cornerstone, employing end-to-end encryption with a zero-knowledge approach. All files and metadata receive protection using randomly generated encryption keys that never travel in unencrypted form. Data is secured with AES-256 encryption, and new keys are generated each time a file changes.
Distinctively, Tresorit applies a Message Authentication Code (MAC) to each file's content, with the code known only to your device and those you've shared with—but not stored by Tresorit itself. This ensures files cannot be modified without your knowledge, even if their system was compromised. Due to this robust security architecture, not even Tresorit staff can access your files.
For businesses requiring maximum compliance, Tresorit offers customizable server locations to meet data residency requirements and maintains certification for compliance with ISO 27001:2022.
