Where Everabyte wins

What you get that Proton Drive doesn't offer.

Post-quantum encryption

Proton uses classical X25519 + AES-256. Everabyte uses hybrid X25519 + ML-KEM-768 (NIST FIPS 203) — your files stay safe when quantum computers become mainstream.

Built-in access contracts

NDA, geo-restrict, time windows, watermarks. Proton Drive has none of these — you'd need an external e-signature tool.

HPKE-encrypted recovery keys

Proton's strict zero-access = lose your password, lose your files. Everabyte offers HPKE-encrypted recovery keys as an opt-in safety net.

Multi-region by default

Everabyte offers 12 storage regions across three continents. Proton is Swiss + EU only.
