Full Review
Overview
Sync.com is a Canadian cloud storage provider that makes zero-knowledge encryption the default, not an add-on. Every file is encrypted on your device before upload, and Sync.com never has access to your encryption keys. This makes it one of the most privacy-focused mainstream cloud storage services.
Storage and Pricing
Sync.com offers 5GB of free storage. The Solo Basic plan provides 2TB for $8/month (billed annually). The Solo Professional plan offers 6TB for $20/month. For teams, the Teams+ Unlimited plan provides unlimited storage at $15/user/month. The Personal plan at $5/month offers 200GB.
Key Features
Sync.com stands out with zero-knowledge encryption as a standard feature on all plans, including the free tier. File versioning goes back 180 days on paid plans — far more than most competitors. Secure sharing with password protection and expiry dates gives you control over shared files. The Vault feature provides long-term archival storage.
Security
Sync.com uses AES-256 encryption with zero-knowledge architecture by default. Files are encrypted client-side before upload. Two-factor authentication, remote wipe, and granular sharing permissions add layers of protection. Sync.com is compliant with PIPEDA, GDPR, and HIPAA regulations. Data is stored exclusively in Canadian data centers.
Who Should Use Sync.com
Sync.com is the best choice for privacy-conscious users who want zero-knowledge encryption without paying extra or configuring complex settings. It is also excellent for businesses needing HIPAA compliance and teams requiring secure file sharing with external partners.
