Description
Imagine mailing your important documents to a storage locker, but the letter is sealed inside a lockbox that only you hold the key to — not even the postal service can peek inside. That is the basic idea behind DragBin: it's an online storage service, like the cloud drives you already use for photos and files, except the company running it says it genuinely cannot open your folders, read your videos, or scan your documents, because everything is locked up before it ever leaves your computer or phone.
Under the hood, DragBin encrypts files client-side before upload, combining AES-256 and ChaCha20-Poly1305 for the actual data encryption with ML-KEM, a post-quantum key-encapsulation algorithm, layered on top for key exchange. It ships as native apps for macOS, Windows, Linux, iOS, and Android plus a web client, and covers the usual cloud-storage feature set: unlimited bandwidth, file sharing, and media synchronization. Plans range from a 5 GB free tier through Personal, Professional, Creator, and Business tiers, with the top end adding team workspaces for up to 2,000 users, SSO, and per-team access controls aimed at legal practices and content-heavy organizations.
💬 Our review
The short version: DragBin is a solid, genuinely private cloud storage option if you want E2E encryption without paying Tresorit-level prices, but "post-quantum" is mostly a marketing hook rather than something you need today.
Compared to Proton Drive (roughly $9.99/month for 200 GB via the Proton Unlimited bundle), Tresorit (from around $10.42/month for 1 TB), and Sync.com ($8/month for 2 TB on the Solo Basic plan), DragBin's Personal tier — 500 GB for $3/month — is hard to beat on raw price-per-GB, since none of the big three encrypted-storage names offer that much space that cheap. But it isn't uniformly the cheapest: Sync.com's 2 TB Solo plan at $8/month actually undercuts DragBin's Professional tier (2 TB for $10/month). The client-side AES-256 + ChaCha20-Poly1305 encryption is a real, meaningful security property — DragBin genuinely can't read your files. The ML-KEM post-quantum layer, on the other hand, is defending against an attack (a working cryptographically-relevant quantum computer) that doesn't exist yet — useful as future-proofing, not a reason to pick DragBin over competitors today. The real value proposition here is price-per-GB with solid encryption, not the quantum angle.
