Proton Drive is a highly secure, privacy-focused cloud storage solution developed by the team behind the renowned ProtonMail. Based in Switzerland, the platform is designed from the ground up to protect user data with strict end-to-end encryption. Unlike mainstream providers that can scan your files for advertising or compliance purposes, Proton Drive utilizes zero-knowledge architecture, meaning only you possess the cryptographic keys required to decrypt and view your documents, photos, and folders. The interface is intentionally clean and minimalist, prioritizing security over flashy integrations. It offers robust file sharing capabilities, allowing users to generate encrypted, password-protected links with precise expiration dates to share sensitive documents with external parties safely. Because the company is headquartered in Switzerland, all user data is protected by some of the world's strictest privacy laws, placing it entirely outside the jurisdiction of US and EU surveillance networks. **Pricing:** Proton Drive offers a Free plan providing up to 5GB of encrypted storage. The Drive Plus plan costs $4.99/month (billed annually at $47.88) and provides 200GB of storage. Users can also subscribe to Proton Unlimited for $12.99/month ($119.88/yr), which includes 500GB of storage plus premium access to ProtonMail, VPN, and Calendar.
