Automatic, real-time file synchronization across every device. End-to-end encrypted. Zero-knowledge architecture. Trusted by 12,000+ organizations worldwide.
Install the desktop agent, choose your folders, and forget about it. CloudSync keeps everything up to date in the background — automatically, securely, continuously.
Download the CloudSync agent for Windows, macOS, or Linux. Sign in once — the agent runs silently in the background, syncing files as they change.
Changes are detected instantly via filesystem watchers. Modified files are encrypted, deduplicated, and uploaded within seconds. No manual action needed.
Files are encrypted on your device before leaving it. We never see your data — zero-knowledge architecture means only you hold the keys.
The CloudSync daemon continuously monitors your selected folders and syncs changes in real time. It uses minimal CPU and bandwidth thanks to delta-sync technology — only changed blocks are transferred.
Native agents for every major platform. Web access when you need it. Mobile apps for on-the-go access.
Windows 10/11. Silent background service. Explorer integration. System tray controls.
macOS 12+. Finder integration. Menu bar agent. Apple Silicon native.
Ubuntu, Debian, Fedora, Arch. Headless CLI mode for servers. Systemd service.
Browser access from anywhere. iOS and Android apps with selective sync.
Every file is encrypted before it leaves your device. Our zero-knowledge architecture means we physically cannot access your data — even under court order.
Military-grade encryption with authenticated encryption. Keys derived client-side via HKDF-SHA256. We never see your plaintext.
Your encryption keys never leave your device. We store only ciphertext. Even our engineers cannot read your files.
SOC 2 Type II audited. GDPR, HIPAA, and CCPA compliant. ISO 27001 certified infrastructure. Detailed audit logs.
From solo developers to Fortune 500 enterprises. CloudSync scales with your needs.
Sync build artifacts, shared libraries, and configuration across dev environments. Git-friendly — respects .gitignore patterns. Integrates with CI/CD pipelines.
HIPAA-compliant file sharing for patient records, imaging data, and research datasets. Granular access controls and full audit trails.
Secure document management with client-matter organization. Ethical wall support. Automated retention policies. eDiscovery-ready exports.
We evaluated Dropbox Business, Box, and SharePoint. CloudSync was the only solution that gave us true zero-knowledge encryption without sacrificing the seamless sync experience our team needed. The background agent just works — our engineers don't even think about it anymore.
