Post-quantum encrypted cloud storage with a 25GB free start
DragBin is a cloud storage and file-sharing service betting on encryption as its identity: client-side and end-to-end encryption, zero-knowledge architecture, and post-quantum protection built on ML-KEM alongside AES-256. Feature set covers storage, sync across devices, password-protected and expiring share links, access controls, analytics, virtual data rooms, global edge acceleration and cross-cloud integrations — free to start with 25GB.
The post-quantum angle is forward-looking rather than marketing fluff: "harvest now, decrypt later" is a real concern for files with long sensitivity lifetimes, and few consumer services have shipped ML-KEM support.
Who it's for: creators and small businesses whose files include client material, contracts or anything that should stay private for years, and privacy-conscious users who want the storage provider structurally unable to read their content. The usual caveat for zero-knowledge services applies: lose your password, lose your files — that's the trade you're choosing. Compare the paid tiers against the incumbents on price-per-GB, but for sensitive material the encryption architecture is the feature.
