4/5

Overall Safety Score

★ ★ ★ ★ ★

Verdict: Google Drive is technically very secure with world-class infrastructure. The trade-off is that Google can and does access your files for various purposes including AI training and policy enforcement. For sensitive data, use client-side encryption.

Google Drive is one of the most widely used cloud storage platforms with over 1 billion users. It benefits from Google's massive security infrastructure but is not zero-knowledge encrypted, and files are accessible to Google.
