Why Privacy Matters in Cloud Storage
Cloud storage is convenient, but without proper security measures, sensitive data can be vulnerable to cyber threats, data breaches, and government surveillance. Choosing a privacy-focused cloud provider ensures your files remain protected from unauthorized access.
Key Features to Look for in a Private Cloud Storage Service
- End-to-End Encryption (E2EE) – Ensures only you have access to your files.
- Zero-Knowledge Architecture – The provider cannot access or read your data.
- Open-Source Code – Allows independent security audits.
- Strong Data Ownership Policies – Prevents data harvesting and tracking.
- Cross-Platform Accessibility – Syncs securely across multiple devices.
