Popular cloud storage services protect your data through policies and procedures, not cryptography. Learn why this matters and what true zero-knowledge security looks like.

Why Dropbox and Box Aren't Zero-Knowledge: Understanding the Security Gap

Many professionals trust services like Dropbox, Box, and Google Drive with their most sensitive files, assuming these platforms provide adequate security. However, there's a crucial distinction between policy-based security and cryptographic security that every organization should understand.

How Traditional Cloud Storage Works

When you upload files to Dropbox or Box:

Files are transmitted (usually encrypted in transit)
Stored on their servers with server-side encryption
The service provider holds the encryption keys
Employees with proper access can potentially view your files

Policy-Based Security: The Human Factor

These services protect your data through:

Employee background checks and training
Access controls and monitoring systems
Compliance certifications and audits
Legal agreements and privacy policies

While these measures are valuable, they introduce human and procedural risks that cryptography eliminates entirely.

Zero-Knowledge: Cryptographic Certainty

True zero-knowledge systems like EncryptedZip work differently:

Files are encrypted on your device before upload
Only you possess the decryption keys
The service provider cannot access your data, even if compelled
Security relies on mathematics, not policies

Experience true zero-knowledge security with EncryptedZip - where your data privacy is mathematically guaranteed, not just promised.
