When selecting a file syncing solution for personal or enterprise use, security should be a top priority. Below are the key areas you should evaluate before committing to a service:

  1. Encryption at Rest & in Transit – Ensure the provider uses AES‑256 encryption for stored data and TLS 1.3 for data in motion.
  2. Zero‑Knowledge Architecture – The service should not have access to your encryption keys.
  3. Compliance Certifications – Look for SOC 2, ISO 27001, GDPR, or HIPAA compliance, depending on your industry.
  4. Access Controls & MFA – Ability to enforce multi‑factor authentication and granular permission levels.
  5. Versioning & Ransomware Protection – The service should retain file versions and provide quick recovery options.
  6. Endpoint Security – Compatibility with antivirus, endpoint detection, and device management solutions.
