This comparison pits two giants of zero-knowledge privacy against each other. Proton Drive leverages its comprehensive ecosystem and generosity with a 5 GB free plan. Tresorit focuses keenly on robust organizational compliance and specialized security features like eSign. Both suffer from reported customer service and performance issues, making the choice about feature priority.
Unmatched Security, Needs Operational Polish
We find Proton Drive's foundation, built on end-to-end encryption and Swiss privacy law, to be industry-leading and structurally sound. However, external feedback detailing poor performance, unhelpful support, and confusing billing management raise serious questions about operational reliability and user experience. Overall, this is the premier choice for zero-knowledge security, provided you tolerate potential customer service hurdles.
Ultra-Secure Platform with Usability Hurdles
Tresorit provides industry-leading zero-knowledge encryption, effectively securing sensitive data for compliance-heavy organizations. We recognize its complex structure targets users who prioritize full control over interface simplicity, but we found consistent reports of slow sync speeds, migration difficulties, and unresponsive customer support. Overall, Tresorit is a specialized tool best suited for organizations where absolute security outweighs functional refinement.
Proton Drive is a cloud storage service designed with privacy as its primary focus. It comes from the creators of Proton Mail and Proton VPN, systems trusted by millions to protect their data. Unlike conventional cloud systems, Proton commits to privacy by default. ✨

Trusted by over 11,000 organizations, Tresorit offers a proven way to work securely, internally and externally.
We highlight the main differences and pick a winner for each feature.
Both offer top-tier E2EE security, but Proton Drive offers open-source transparency.
Proton Drive uses end-to-end encryption; files and metadata are encrypted locally on your device. This protection is backed by strict Swiss privacy laws, offering robust legal defense. Tresorit utilizes zero-knowledge E2E encryption, ensuring Tresorit cannot access or view your content. It appeals strongly to organizations needing absolute data control. While both secure your data profoundly, Proton Drive offers open-source transparency which Tresorit does not explicitly mention. The security commitment in both platforms means maximum protection against data breaches and corporate surveillance efforts.
Proton Drive offers a permanent free tier; Tresorit requires customized quotes after a trial.
Proton Drive provides a generous, permanent Free plan that includes 5 GB of secure storage. This allows testing everything risk-free for life. Tresorit offers a 14-day free trial to explore its full capabilities before requiring a purchasing commitment. You must request a custom quote afterwards. Proton Drive offers clear tiered plans allowing easy upgrades, whereas Tresorit's pricing is opaque and customized by specialized products. If budget and accessing free, secure storage are critical, Proton Drive is the clear and immediate choice for individuals.
Tresorit allows choosing physical data storage location, crucial for regulatory mandates.
Proton Drive is based solely in Switzerland, relying on strong Swiss law to protect all user data. This is great for privacy but lacks residency options. Tresorit offers custom data residency options, allowing users to select Swiss, GDPR-compliant, or other overseas locations. For large organizations needing to meet complex international compliance standards, Tresorit’s flexibility is a huge advantage. This feature is often mandatory for businesses that must physically keep data within specific geographic borders for legal reasons.
Tresorit offers specialized data rooms and eSign; Proton Drive provides basic document editing.
Proton Drive provides a basic online document editor for real-time writing and sharing within the secure platform. File syncing is also available primarily for Windows users. Tresorit offers specialized products like Engage, which establishes confidential, branded data rooms for client collaboration. Tresorit further enhances collaboration with an integrated eSign feature for managing document approvals efficiently in one place. Tresorit is designed structurally as a secure collaboration suite, while Proton Drive is primarily secure storage with basic teamwork functions.
Proton Drive bundles its entire security suite; Tresorit connects with productivity apps.
Proton Drive integrates deeply with the entire Proton product suite (Mail, VPN, Password Manager). The Unlimited plan gives you access to everything. Tresorit integrates with external productivity tools like Google and Outlook for streamlined workflow management. Choosing Proton Drive means buying into a holistic, interconnected security platform maintained by one excellent vendor. Tresorit users benefit from tools like the Email Encryption add-on to secure emails sent through traditional providers like Outlook.
Both services are heavily criticized by users for frustratingly slow upload and synchronization speeds.
Proton Drive reviews frequently cite very slow upload speeds and general operational reliability issues. Data recreation from old backups has unfortunately been necessary for some users. Tresorit users also report consistently slow synchronization and upload speeds compared to standard cloud providers. Glitches can cause files to vanish temporarily on occasions. The latency issue likely relates to the intense, mandatory client-side zero-knowledge encryption process used by both providers. Neither platform wins on raw speed, indicating that maximum privacy requires a patience trade-off in both cases.
Neither platform performs well here; both face severe complaints about unresponsiveness.
Proton Drive support is widely criticized as painfully slow, unhelpful, and providing only generic replies to complex issues. Billing complaints and slow resolution times are common. Tresorit support is frequently deemed unresponsive, ignoring critical technical issues for months, even for paying business clients. Users report feeling "ghosted" by both companies when major technical problems or billing disagreements arise. If reliable, timely customer support is a necessity for your business, neither Proton Drive nor Tresorit currently appears trustworthy.
Tresorit offers more granular control over external file sharing via watermarks and limits.
Proton Drive lets you secure shared links using passwords, auto-set expiration dates, and offers instant access revocation. Tresorit adds powerful controls like file watermarks, limits on how many times a file can be opened, and enforced passwords. Tresorit is clearly superior when sharing highly sensitive final documents externally where leakage prevention is critical. For basic secure sharing, Proton Drive works well, but Tresorit provides the full suite of leakage prevention safeguards.
Ultimately, the choice between Proton Drive and Tresorit hinges on your specific security needs. Proton Drive is the stronger choice for individuals and small teams seeking holistic digital privacy. Tresorit is better suited for corporate environments demanding specialized regulatory control and compliance features. Proton Drive’s superpower is its unified security ecosystem, offering 5 GB free storage plus integrated access to Proton Mail and VPN. It operates completely on open-source code and secures user data under strict Swiss privacy laws. If comprehensive, transparent privacy is your goal, Proton Drive delivers excellent value. Tresorit's superpower is deep organizational control and specialization, evident in tools like integrated eSignatures and secure data rooms (Engage). Furthermore, Tresorit offers custom data residency, a non-negotiable feature for highly regulated businesses worldwide. Your budget and regulatory obligation are the deciding factors. If complex legal compliance or digital signing is necessary, Tresorit is the superior platform. If you want maximum security bundled with other essential privacy tools, Proton Drive is the clear winner for value. Be warned, customer support reviews are abysmal for both Proton Drive and Tresorit.
Proton Drive is generally better for individuals due to its generous, permanent 5 GB free plan. Tresorit focuses more on custom organizational solutions and requires specialized quotes. Proton Drive also integrates seamlessly with the full Proton security ecosystem.
Tresorit is worth the cost if you need advanced features like integrated document eSignatures or custom data residency options. If you only need secure storage and sharing, Proton Drive offers better immediate value and features transparency. Pricing for Tresorit is opaque and requires a quote.
