Key differences

Tresorit is encrypted storage. DeadVault is encrypted delivery. The distinction matters.

Tresorit is zero-knowledge. DeadVault is not.

This is the most important difference. Tresorit encrypts files on your device before they reach the server, Tresorit cannot read your data even if compelled to. DeadVault encrypts files server-side with AES-256-GCM and per-file keys, but the system holds the master key. If your top priority is preventing even the platform itself from accessing files, Tresorit's model is genuinely stronger.

Tresorit stores files. DeadVault destroys them.

Tresorit is fundamentally a cloud storage and sync tool, files live there indefinitely until you delete them. DeadVault is ephemeral by design: files exist until a deadline you set, then encryption keys are destroyed, making the data mathematically unrecoverable. For professionals who need to deliver files and prove they're gone, storage is the wrong model.

Tresorit is per-user. DeadVault is per-practice.

Tresorit charges per user at ~$14/user/month. A five-person accounting firm pays ~$70/month for encrypted storage. DeadVault is $19/month flat. Your whole team uses one account, and clients never need accounts at all. For small practices, the cost difference is significant.

Tresorit requires accounts for full access. DeadVault doesn't.

Tresorit can share files via link, but recipients get limited functionality without a Tresorit account. Full collaboration requires everyone to be on Tresorit. DeadVault gives clients a single secure link: click, upload, download, done. No accounts, no apps, no onboarding friction.

Where Tresorit is the better choice

Tresorit is an excellent product. Here's where it genuinely outperforms DeadVault.

✓True zero-knowledge encryption: the platform cannot access your files

✓End-to-end encryption where files are encrypted before leaving your device

✓Swiss jurisdiction with strong privacy protections

✓GDPR, HIPAA, and CCPA compliance certifications

✓Excellent for long-term encrypted cloud storage and file sync

✓Mature desktop and mobile apps with seamless sync

Common questions

In one specific way, yes. Tresorit uses true zero-knowledge, end-to-end encryption, files are encrypted on your device before upload, and Tresorit never has access to your encryption keys. DeadVault uses AES-256-GCM with per-file keys, but encryption happens server-side and the system holds the master key. Tresorit's model protects against the platform itself being compromised or compelled. DeadVault's model protects against external breaches and ensures files are cryptographically erased at deadline. Different threat models, different strengths.

Because encryption strength isn't the only consideration. If you're a CPA delivering tax returns, you need files to self-destruct at a deadline, payment gates to collect fees, a branded client portal, bidirectional file exchange, and zero friction for clients. Tresorit gives you excellent encrypted storage, but storage is the wrong model for ephemeral delivery. You'd be giving clients access to a folder they need to remember to check, rather than a single-purpose link that handles itself.

Tresorit does not have built-in automatic file destruction or cryptographic erasure. You can manually delete files and folders, but there's no deadline-based destruction and no proof that encryption keys were destroyed. For professionals who need to demonstrate that client data was erased after a retention period, this is a meaningful gap.

For basic link-based file sharing, no, Tresorit can generate shareable links. But recipients get limited functionality without an account. Full collaboration, folder access, and file uploads typically require a Tresorit account. DeadVault never requires client accounts, the secure link is the entire experience.

Yes. Tresorit offers HIPAA compliance and will sign Business Associate Agreements. This is one of Tresorit's genuine strengths. DeadVault also offers BAAs on Enterprise plans, but Tresorit's zero-knowledge architecture provides a stronger technical foundation for HIPAA compliance.

Absolutely, and some firms do. Use Tresorit for long-term encrypted storage of internal documents and firm files. Use DeadVault for client-facing file delivery: sending tax returns, collecting signed engagement letters, gating document access behind payments. They solve different problems and complement each other well.

Delivery that destroys itself

Tresorit keeps your files safe forever. DeadVault delivers them securely and makes them disappear on schedule. Pick the right tool for the job.
