Dropbox vs Alternative Europee: Confronto Completo delle Funzionalità

Tresorit is the security benchmark against which every other cloud storage provider in this comparison is measured. Its zero-knowledge architecture means files are encrypted with AES-256 on your device before they leave it, and the RSA-4096 key exchange ensures that even Tresorit employees cannot access your data. This is not a marketing claim — it has been independently verified by TÜV Rheinland (ISO 27001) and Ernst & Young.

Where Tresorit falls short is accessibility and price. There is no free plan, and the cheapest tier costs $5.99/month for just 50 GB. The Personal Essential plan at $11.99/month for 1 TB is comparable to Dropbox Plus in price but without the ecosystem integrations. Real-time document co-editing is absent — you get shared folders and link sharing, but no Google Docs-style collaboration. The desktop app interface is clean, but multiple users report slower sync speeds compared to Dropbox.

For businesses in regulated industries — legal firms, healthcare providers, financial services — Tresorit's HIPAA compliance, granular access controls, and zero-knowledge architecture justify the premium. For personal use with casual file sharing needs, the cost may be harder to justify.

Proton Drive's strongest asset is not any single feature but the ecosystem behind it. As part of the Proton suite — alongside Proton Mail, Proton VPN, and Proton Calendar — it offers a unified, end-to-end encrypted workspace where your email, files, and calendar are all protected under Swiss privacy law. The encryption uses ECC Curve25519 with OpenPGP, and all client applications are open source and audited by Securitum.

The honest trade-off is performance. In Cloudwards' 2026 benchmarks, Proton Drive ranked last among major providers for upload and download speed — MEGA and pCloud were roughly nine times faster. Users on Privacy Guides forums report multi-day sync times for collections over 200 GB. There is no Linux desktop client yet, no block-level sync, and the Proton Docs editor trails Google Docs significantly in capabilities.

Proton Drive makes sense if you already use Proton Mail and want everything under one encrypted roof. The 5 GB free tier shared across all Proton services is generous enough to evaluate. But if raw sync speed or advanced collaboration features are priorities, Proton Drive is not there yet.

pCloud's defining feature is its lifetime plans: pay €199 once for 500 GB, €399 for 2 TB, or €1,190 for 10 TB, and the storage is yours permanently. For users tired of recurring subscriptions, this is genuinely appealing — the 2 TB plan breaks even against Dropbox Plus in under three years. The desktop client uses a virtual drive approach that mounts cloud storage as a local disk, and pCloud's built-in media player handles 4K video streaming directly from the cloud.

The critical caveat is encryption. Unlike Tresorit or Filen, pCloud does not include end-to-end encryption by default. The pCloud Crypto add-on costs an additional $49/year (or $125 lifetime) and only encrypts files placed in a dedicated Crypto folder. Without it, pCloud holds your encryption keys and can technically access your files. This is a recurring criticism in privacy-focused communities and a meaningful distinction from competitors that encrypt everything by default.

There are also trust concerns: multiple users report accounts being deleted over copyright claims with limited recourse, and one detailed review documents losing 32 days of production files after a reinstall. pCloud works well as affordable, general-purpose cloud storage with EU data residency in Luxembourg. But if zero-knowledge encryption is a requirement, factor in the Crypto add-on cost or look elsewhere.

Filen offers the best combination of free storage and zero-knowledge encryption in this comparison. The free tier includes 10 GB with full client-side AES-256-GCM encryption enabled by default — no add-on, no upsell. Paid plans start at just €1.99/month for 200 GB, making it the cheapest zero-knowledge option available. The entire codebase is open source on GitHub, and data is stored exclusively in German data centers.

The trade-off is maturity. Filen is built by a small team, and it shows in stability reports: users on Trustpilot and testing blogs document sync loop bugs, occasional file deletion issues, and download speeds throttled to 500 KB/s even on premium plans. Filen acknowledged these issues and planned a Rust-based sync engine rewrite for late 2025. There are no dedicated business plans, no real-time document collaboration (only an encrypted notes editor), and no media streaming.

Filen is a strong choice as a secondary encrypted backup or for privacy-conscious users on a tight budget. For a primary cloud drive replacing Dropbox for daily work, the sync reliability concerns are hard to ignore. Give it time — the fundamentals (encryption, pricing, openness) are right, and the team is actively addressing the weak points.

Internxt offers the lowest per-terabyte pricing of any zero-knowledge encrypted provider in this comparison: 1 TB for €24/year (roughly €2/month) and lifetime plans from €299 for 2 TB. The company is based in Valencia, Spain, with data centers across France, Germany, and the Netherlands. It is open source, audited by Securitum, and holds both ISO 27001 and SOC 2 certifications — an impressive compliance portfolio for a younger company.

The problems are operational. In Cloudwards' speed tests across 23 providers, Internxt ranked near the bottom, with uploads taking over an hour for test folders that competitors processed in under 10 minutes. Community reports on GitHub document upload failures between 96-98% completion that leave files missing. Customer support is widely described as non-responsive — one Trustpilot reviewer reported contacting Internxt eight times through different channels without resolution. In late 2025, the company temporarily restricted WebDAV and rclone access for existing users, breaking a feature that was a selling point for technical users.

Internxt's pricing and privacy credentials are compelling on paper. But until upload reliability and customer support improve materially, it is difficult to recommend for anything beyond archival storage of files you can afford to re-upload.

Nextcloud is fundamentally different from every other provider in this comparison: it is free, open-source software (AGPL-3.0) that you install on your own server. You control the hardware, the encryption keys, the jurisdiction, and the data. There is no subscription, no storage limit beyond your own hardware, and no third party with access to your files. France's public sector runs six-figure Nextcloud deployments, and the German federal government uses it internally.

The Nextcloud ecosystem extends well beyond file storage. With Collabora Online or OnlyOffice integration, you get real-time document editing comparable to Google Workspace. Nextcloud Talk provides video conferencing. Nextcloud Mail, Calendar, and Contacts round out the productivity suite. The app store includes hundreds of extensions.

The honest downside is complexity. Self-hosting requires system administration skills — installation, updates, backups, SSL certificates, and troubleshooting are your responsibility. Users on forums consistently report setup difficulties, sync conflicts, and performance issues especially with the Mail app. File deletion bugs appear in multiple review sources. If you have a sysadmin on staff or are comfortable with Linux servers, Nextcloud gives you sovereignty no managed service can match. If you want something that works out of the box, look at the managed options above.

Infomaniak kDrive is the closest thing to a European Google Workspace in this comparison. It combines 2 TB of Swiss-hosted cloud storage with a full OnlyOffice integration for real-time collaborative editing of documents, spreadsheets, and presentations. The 15 GB free tier is the most generous among the Swiss providers, and the Solo plan at CHF 5.54/month for 2 TB undercuts Dropbox Plus while including an office suite.

Infomaniak operates its own data centers in Geneva and Winterthur, is ISO 27001 certified, and powers over a million Swiss businesses. The company positions itself as a comprehensive alternative to Google and Microsoft, also offering email (Infomaniak Mail), video conferencing (Infomaniak Meet), and website hosting.

The limitation is encryption: kDrive does not offer end-to-end or zero-knowledge encryption. Files are encrypted server-side with AES-256, but Infomaniak holds the keys. For team collaboration where real-time document editing matters more than client-side encryption, this is an acceptable trade-off. For users who need zero-knowledge guarantees, Tresorit or Proton Drive are better fits. kDrive is the pick when you want the Dropbox-plus-Google-Docs experience hosted entirely in Switzerland.

Koofr occupies a unique niche: it is a cloud storage aggregator that can connect to your existing Google Drive, Dropbox, and OneDrive accounts, letting you manage files across multiple providers from a single interface. Its own storage starts at just €0.50/month for 25 GB, making it the cheapest entry point in this comparison. The 10 GB free tier is competitive, and data is stored in ISO 27001-certified data centers in Germany.

Security is Koofr's weak point in this lineup. The base service uses server-side AES-256 encryption but is not zero-knowledge — Koofr can access your files to provide previews and search. The free Koofr Vault add-on enables client-side encryption for selected folders, but this is opt-in and folder-specific rather than system-wide. The desktop client lacks selective sync, and there is no real-time document collaboration.

Koofr makes sense as a multi-cloud management hub for users who want to consolidate access to multiple storage providers under one EU-based interface. It also works well as affordable backup storage. But for users prioritizing end-to-end encryption or collaboration features, other providers in this comparison are stronger choices.

Jottacloud is a Norwegian cloud storage provider that has been operating since 2008, making it one of the most established European alternatives in this comparison. Its standout feature is the Pro Unlimited plan at €11.90/month, which offers unlimited storage — a proposition no other provider here matches. The service excels at photo backup with AI-powered search that understands natural language queries, and the mobile apps are well-regarded for automatic camera roll sync.

The “unlimited” label requires qualification. Jottacloud throttles upload speeds significantly after 5 TB of storage, reducing transfers to approximately 1 Mbit/s. Multiple users report accounts being closed for exceeding what Jottacloud considers reasonable use under their terms of service. This effectively makes “unlimited” more like “large but capped by speed” — fine for gradual photo backup accumulation, problematic for bulk data migration.

Jottacloud does not offer end-to-end or zero-knowledge encryption. Files are encrypted server-side with AES-256 and TLS 1.3 in transit, but Jottacloud holds the keys. Data is stored exclusively in Norway, which is in the EEA and subject to GDPR. The service works well for families and photographers who want simple, large-capacity backup under European jurisdiction without needing zero-knowledge encryption.
