Tresorit
The compliance-grade encrypted drive: Swiss zero-knowledge storage with SOC 2 and ISO 27001, for regulated teams.
About
Tresorit is the cloud drive you pick when auditors are watching. Founded in 2011 and Swiss-based, it puts AES-256 client-side encryption on every plan, with SOC 2 Type II, ISO 27001, ISO 27018, and FIPS 140-2 certifications, GDPR/HIPAA/CCPA/TISAX compliance, and data residency across 12 regions. The 2026 lineup: a 3 GB free Basic plan, Professional for solo users at about $27.49/month on annual billing, Business at $19/user/month annual (3-user minimum), and Business Pro at $24/user/month annual (5-user minimum). Business tiers include eSignatures (SES and eIDAS QES) and granular per-file permissions, Outlook/Teams integration, and secure file-request links for outsiders.
Honest limits: it is the priciest option per terabyte in the encrypted category, and unlike Dropbox there is no block-level sync — editing a large file re-uploads it whole, which hurts on slow connections. The free tier is a 3 GB trial-sized allowance. No published performance benchmarks found; sync-speed claims are provider-claimed.

Trust score — 8/10
Scored 8/10 (VERIFIED tier, metrics-v1). Evidence: 2026 plan restructure and pricing from ifeeltech's six-month hands-on review; certifications (SOC 2, ISO 27001, E&Y NIS2 audit) cross-confirmed by tech-insider and securityonline. Strengths: the strongest audited compliance posture in consumer-accessible encrypted storage, granular admin controls, Swiss jurisdiction. Docked for: (1) premium pricing — priciest per TB in the encrypted set; (2) no block-level sync, so large-file edits re-upload whole files. License: proprietary SaaS.
