When your business needs to store sensitive files in the cloud, the choice isn’t really about storage capacity, it’s about how much you trust the platform with your data. Both Tresorit and Sync.com are built on zero-knowledge encryption, which means even their own servers can’t read your files. But that’s roughly where the similarity ends.
Tresorit is built for regulated industries and enterprise teams that need more than just encryption. Think HIPAA compliance, GDPR-ready data processing agreements, ISO 27001 certification, and granular digital rights management (DRM) controls that let admins restrict what users can do with shared files. It’s a serious business tool with a price tag to match.
Sync.com targets a different audience: small businesses, freelancers, and privacy-conscious individuals who want zero-knowledge cloud storage without paying enterprise rates. It offers a generous free tier and affordable paid plans, and the security fundamentals are solid, just without the compliance infrastructure that regulated industries demand.
This comparison breaks down the real differences in security architecture, pricing, collaboration tools, and who each platform is actually built for, so you can make the right call for your situation.
⚡ Quick Verdict
- →Pick Tresorit if you work in a regulated industry (healthcare, legal, finance) and need enterprise compliance certifications, DRM controls, and granular user permissions.
- →Pick Sync.com if you’re a small business or freelancer who wants solid zero-knowledge storage at a lower price point, including a usable free tier.

Tresorit Overview
Tresorit is a Swiss-based encrypted cloud storage platform founded in 2011 with one mission: make business file storage genuinely private. It uses end-to-end encryption with AES-256 keys that never leave your device in plaintext, not even Tresorit’s servers can access your files. That zero-knowledge architecture is backed by formal compliance certifications: HIPAA, GDPR, ISO 27001, and SOC 2.
What sets Tresorit apart from other zero-knowledge providers is the business layer on top of encryption. Admins get granular DRM controls, you can share a file and prevent the recipient from downloading, printing, or forwarding it. You get full audit logs, remote wipe, user management, and data residency controls (EU or US). It integrates with Microsoft 365, Outlook, and Azure AD, making it a natural fit for enterprise IT environments.
For teams in healthcare, legal, or finance where data handling is subject to regulatory scrutiny, Tresorit is one of the few cloud storage platforms that can check every compliance box. Explore Tresorit’s business plans to see which tier fits your team size. If your organization already has roundup posts on best secure cloud storage for business, Tresorit consistently ranks at the top for regulated industries.
Sync.com Overview
Sync.com is a Canadian cloud storage service that has been offering zero-knowledge encrypted storage since 2011. Like Tresorit, files are encrypted client-side before upload, Sync.com cannot read your data. It’s PIPEDA-compliant and operates under Canadian privacy law, which many consider more protective than US law (no PATRIOT Act exposure).
What Sync.com trades in enterprise features, it makes up for in affordability and accessibility. The free tier offers 5GB of zero-knowledge storage, rare in this space. Paid plans start around $8/month and scale to team plans with shared folders, user management, and admin controls. The interface is clean and accessible for non-technical users, with solid mobile apps for iOS and Android.
Sync.com doesn’t offer the same DRM controls, compliance certifications, or enterprise integrations as Tresorit, but for small businesses and freelancers who need private cloud storage without the enterprise price tag, it delivers the fundamentals well. Sync.com’s website has a transparent feature comparison by plan.
Pricing Compared
Pricing is one of the sharpest differences between these two platforms, and it reflects their very different target markets.
Tresorit starts at approximately $15/user/month (Business Standard, billed annually) for teams. Enterprise plans with advanced compliance and DRM features run higher, and pricing is typically discussed with a sales team for larger deployments. There’s no free tier for business use, only a short trial. For individuals, there’s a Tresorit Solo plan around $10-12/month, but the business-grade features require the team plans.
Sync.com is significantly more accessible. The free plan gives 5GB of zero-knowledge storage with no credit card required. Paid Solo plans start around $8/month (2TB storage), and team plans with collaboration features start around $10-20/month depending on user count and storage. Lifetime plans are occasionally offered during promotions.
The pricing gap is real: Tresorit costs roughly double what Sync.com charges for a comparable number of users. The premium buys you formal compliance certifications and enterprise controls, worth every dollar if your industry requires them, but overkill if you’re a freelancer storing client files privately.
Security & Encryption Features
Both platforms use AES-256 end-to-end encryption with zero-knowledge architecture, the encryption keys are generated on your device and never transmitted to their servers in plaintext. This means even if their servers were breached, your data would be unreadable ciphertext.
Tresorit goes further with its compliance stack. It holds ISO 27001 certification, HIPAA-compliant BAAs (Business Associate Agreements), SOC 2 Type II, and GDPR-ready DPAs (Data Processing Agreements). Data residency options let you choose EU or US server locations. The DRM layer adds another security dimension: admins can share files with controls that prevent download, screenshot, printing, or forwarding, rare in any cloud storage product.
Sync.com offers solid baseline security: AES-256 E2E encryption, TLS in transit, and compliance with Canadian PIPEDA regulations. It doesn’t hold the formal enterprise certifications (HIPAA BAA, ISO 27001, SOC 2) that Tresorit does, so it’s not the right choice for a HIPAA-covered entity without independent legal review.
Collaboration & Business Tools
Tresorit is built for teams with real collaboration needs. Shared encrypted workspaces (called Tresors) let multiple users access files with role-based permissions. Admins can set per-user access levels, revoke access remotely, and track who accessed what via audit logs. Integration with Microsoft 365, Outlook add-in for secure email attachments, and Azure Active Directory sync make it enterprise IT-friendly.
Sync.com’s collaboration features are more basic but functional. Shared folders allow team collaboration with permission controls, and the business plans include team admin dashboards and user management. There’s no deep integration with Microsoft 365 or enterprise identity providers. For small teams with straightforward sharing needs, this is fine, but it won’t satisfy IT security teams at larger organizations.
If your team already uses tools listed in our roundup of best encrypted file sharing tools for remote teams, Tresorit’s collaboration controls make it the stronger integration point for business workflows.
Ease of Use & Platform Support
Sync.com has the edge on ease of use for non-technical users. The web interface is clean and intuitive, the desktop sync clients work reliably on Windows and Mac, and the mobile apps (iOS and Android) are polished. Setup takes minutes, and the free tier means you can evaluate the full experience before committing.
Tresorit’s interface is clean but skews toward business users comfortable with admin dashboards. Desktop clients are available for Windows, Mac, and Linux. Mobile apps cover iOS and Android. The Microsoft Outlook plugin adds friction-free encrypted email attachments for enterprise workflows. Onboarding is smoother with an IT team to assist, solo users may find the permission and policy configuration more complex than needed.
Both platforms offer web access without installing software, and both support offline access to synced files. For pure consumer-friendliness, Sync.com wins. For enterprise deployment at scale, Tresorit’s admin tools are more mature.
