As of 1 Nov 2026, the panel rates Dropbox 3/5 and Tresorit 3.5/5 in Cloud Storage & File Sharing. Weighted by what each judge cares about, 1 of the 6 judges picks Dropbox and 5 pick Tresorit. Dropbox scores higher on 2 of 7 criteria (Export, API & self-hosting and Sync, clients & file access). Tresorit scores higher on 4 of 7 criteria (European sovereignty, Sharing & external collaboration, Pricing transparency, plus 1 more). Provenance — Dropbox: Rest of world; Tresorit: UK / wider Europe. Ratings are the AI panel’s opinion, formed from public evidence: how scores are made.
Dropbox and Tresorit split this panel along clear lines. Dropbox is ahead on portability and integrations (6.0 to 4.8, six judges leaning Dropbox) and on sync and access (6.3 to 5.7, two leans, four ties). Tresorit is ahead on sovereignty (7.0 to 2.3, six leans), sharing and collaboration (8.8 to 6.7, six leans) and pricing transparency (5.8 to 5.2, four leans, two ties). Encryption and security sits close at 7.8 to 7.5 — one Dropbox lean, three Tresorit leans, two ties — and administration and governance is 7.0 apiece, six ties. Dropbox's verdict cites 256-bit AES at rest, SSL/TLS in transit, Rewind ransomware recovery and listed SOC and ISO certifications; Tresorit's cites primary storage in the EEA or Switzerland with customer-selectable residency, beside terms disclosing sub-processing in the United States and other countries. Five of six weighted totals favor Tresorit; the architecture practice partner's favors Dropbox, 6.3 to 6.1.
Choose Dropbox if
You need clear paths to move files in and out — portability and integrations is Dropbox's strongest lean, 6.0 to 4.8 with six judges leaning Dropbox, and the captured Tresorit pages show no public information on migration tools, bulk export or a self-hosted edition.
Your team syncs multi-gigabyte BIM files — the architecture practice partner scored Tresorit's sync and access at 4 for want of public information on delta sync and previews for such files, while Dropbox's mean on sync and access is 6.3 to 5.7, with two judges leaning Dropbox and four tying.
You weight the architecture practice partner's judgment highest — that judge's total favors Dropbox, 6.3 to 6.1, the one weighted total of the six that Dropbox takes.
You need ransomware recovery tooling in the verdict record — Dropbox's encryption and security verdict cites Rewind ransomware recovery alongside 256-bit AES at rest and SSL/TLS in transit, with one judge leaning Dropbox and two tying at a 7.5 mean.
Choose Tresorit if
You must keep primary storage in the EEA or Switzerland and choose residency per customer — sovereignty is Tresorit's largest gap, 7.0 to Dropbox's 2.3 with six judges leaning Tresorit, against Dropbox's privacy policy stating data may be stored, processed and transmitted in the United States and locations around the world.
You exchange sensitive files with people outside your organization — sharing and collaboration is 8.8 to 6.7 with six judges leaning Tresorit, on encrypted links with password, expiry, open limits, disabled download and print, watermarks, file requests and zero-knowledge office editing.
You require end-to-end encrypted sync and sharing — encryption and security means run 7.8 to 7.5, with three judges leaning Tresorit, one leaning Dropbox and two tying.
You want a published euro entry price — €12 per user per month from 3 users is published, and pricing transparency is 5.8 to 5.2 with four judges leaning Tresorit and two tying, though the pages give different figures for Business storage and leave extra storage and eSign unpriced.
You follow the panel's overall weighting — five of six weighted totals favor Tresorit, 6.7, 7.2, 7.1, 6.9 and 6.7 against Dropbox's 6.3, 6, 5.7, 6.1 and 5.4.
Read this comparison as one judge. Each weighs the same scores by what they care about.
The Agency Producer
Producer at a 30-person video and design agency in Cologne that sends cuts, layouts and raw footage to customers every day and collects their feedback. Wants review links that play in the browser, comments on the file, transfers of 100 GB that do not stall, freelancers added for one project and removed after it, connections to Slack and the project tool, and a storage bill that does not jump when one shoot fills a terabyte.

Criterion by criterion
Sync, clients & file access
Dropbox
The captured pages show desktop apps for Windows and Mac with online-only files visible in the file explorer, offline folders on desktop and mobile, automatic sync, full-text and image search, previews, and file sizes up to the storage quota starting at 2 GB, backed by a 2023 commissioned study claiming Dropbox outperformed competitors in 86% of sync comparisons. For the rest of the top level — Linux clients, block-level sync, and access via WebDAV, SFTP or S3 — we found no public information.
Tresorit
Clients cover Windows, Mac and Linux plus iOS and Android with automatic camera upload, offline access and cloud files sitting in the local file manager, and per-file limits are published at 15 GB on Business and 20 GB on Business Pro. An S3-compatible API is documented for automated transfers with content staying end-to-end encrypted. We found no public information on delta sync for large files, full-text search, or WebDAV and SFTP access — and those per-file caps matter when I hand over 100 GB of raw footage.
Sharing & external collaboration
Dropbox
Almost everything my studio sends out daily is documented: share links with password, expiry and disabled downloads, watermarking and file locking, file requests for clients without an account, Dropbox Transfer up to 100 GB with download tracking, and Replay with live review, versions and video commenting, plus admin-enforced passwords and expiry on external links and Microsoft Teams named among connected tools. Guest accounts with their own permissions and an add-in that swaps Outlook or Teams attachments for links are things we found no public information on.
Tresorit
Encrypted links with password, expiry, open limits, disabled download and print, dynamic watermarks, allowed viewers and require-email-to-view, plus link activity reports and detailed access logs, give me a customer review link that behaves like a small data room. File requests collect uploads from customers without an account, Outlook, Teams and Gmail add-ins are free, and co-editing is documented on named Collabora Online code with the zero-knowledge model kept intact when sharing. We found no public information on file locking or on revocation reaching copies a client already opened.
Encryption, key custody & recovery
Dropbox
AES-256 at rest, SSL/TLS in transit, two-factor and single sign-on, up to ten years of version history, Rewind of a whole account or folder after ransomware with documented recovery steps, a security whitepaper, and a list of SOC and ISO certifications are all stated. The advanced encryption option — team keys generated by AWS KMS, rotated every 12 months, revocable permanently only by three team admins — sits on Advanced and above, and we found no public information on customer-held keys or the scope of the certifications.
Tresorit
Zero-knowledge end-to-end encryption with AES-256 client-side, RSA-4096 key exchange, non-convergent cryptography and HMAC or AEAD integrity checks is documented in a published whitepaper, two-factor and single sign-on exist, ISO 27001:2022 is stated, and a designated Recovery Administrator can regain users' content with their consent. Version restore and deleted-file recovery are described but without a stated history length, and we found no public information on point-in-time restore of a folder or account, ransomware detection, or a named external audit with its report published.
Administration, audit & governance
Dropbox
The admin console evidence is deep: groups and roles with tiered admins, a filterable activity log exportable as CSV plus an Events API endpoint, retention policies and silent legal holds, remote wipe and device approvals, data classification with real-time DLP alerts, domain verification with account capture, and instant deactivation or transfer of departing users — exactly how I would run freelance crews per project. We found no public information on provisioning through a directory or SCIM, or on SIEM streaming.
Tresorit
A central admin console with exportable audit logs of who accessed, shared or modified files, Azure AD SSO and SCIM provisioning, Active Directory integration, policy profiles with IP filtering, approved devices and timeout rules, blocking of lost devices, admin password reset and Microsoft Sentinel SIEM integration are all documented. We found no public information on retention policies, legal hold, quotas, or data loss prevention — the pieces that turn an admin console into governance I could sign off for client NDAs.
Export, API & self-hosting
Dropbox
API v2 is documented with SDKs in six languages, webhooks, and team plus audit-log endpoints, and there is a migration add-on powered by Movebot, sold through the sales team, that moves files and permissions from on-premise file servers and existing cloud storage into a team account. Machine-readable export and deletion of personal information 30 days after account deletion are stated; we found no public information on open protocols such as WebDAV, S3 or SFTP, or on a self-hosted edition.
Tresorit
An S3-compatible API is documented for automated transfers with content staying end-to-end encrypted, Microsoft 365, Outlook, Teams and Gmail integrations are named, Bring Your Own Azure Storage can place encrypted content in the customer's own Azure account, and deletion of a removed folder's encrypted content within 90 days is stated. We found no public information on bulk export with the folder structure, migration tools from named providers, webhooks, or a self-hosted or on-premise edition.
European sovereignty
Dropbox
Customers outside North America contract with Dropbox International Unlimited Company in Dublin, but the privacy policy only says data may be stored and processed in the United States and locations around the world, with EU-to-US transfers carried by Standard Contractual Clauses and the Data Privacy Framework under FTC oversight, and California law with San Francisco courts governing the terms. We found no public information on an EU hosting option, a subprocessor list, or a data processing agreement.
Tresorit
Tresorit AG is a Swiss company in Zurich, part of Swiss Post, with offices in Germany and Hungary and an EU representative in Budapest; storage is primarily in the EEA or Switzerland with EU, Swiss and other residency regions selectable per user, a subprocessor list is published, a data processing addendum exists and ISO 27001:2022 is stated. The privacy policy acknowledges that personal data may also be transferred to countries outside of the EU or Switzerland, the terms name sub-processors in the United States, and we found no named data centres behind the residency options — European at its core, but the chain is not closed.
Pricing transparency
Dropbox
Standard at €12 per user per month starting at 3,000 GB for the team and Advanced at €18 per user per month starting at 15 TB are public, with minimum users stated, restore windows of 180 days and one year, and transfer limits of 100 GB per tier. Enterprise is "Contact sales for pricing", the migration and data governance add-ons are sold through sales, some admin reports vary by plan, and we found no public information on the cost of storage beyond the starting pools or on VAT treatment.
Tresorit
FileSharing Business is €12 / user / month starting from 3 users with 1 TB encrypted storage per user, Business Pro is €20 / user / month starting from 5 users with from 15 TB encrypted storage, a yearly 20% discount is published, and VAT-exclusive pricing plus the auto-renewal, no-refund and trial-conversion terms are public. Enterprise is Custom pricing, and we found no public prices for extra storage or add-ons such as eSign, so I cannot compute a full year's bill for thirty people with terabyte-heavy shoots from the pages alone.
