Google Drive, Dropbox, and WeTransfer store your files permanently on their servers and retain metadata about who uploaded, downloaded, and shared content. This creates long-term privacy exposure that most users never consider.

Cloud storage platforms are optimized for collaboration and persistence, not confidentiality. If your goal is to send files securely online without leaving a permanent trail, you need a fundamentally different architecture.

Google Drive encrypts files at rest, but Google holds the keys and can access your content. VaultBridge uses browser-side AES-256-GCM encryption where decryption keys never leave your device. Even we cannot read your files.

With VaultBridge, there is no login, no account, no tracking cookies, and no analytics. Every file is encrypted before upload, stored as temporary encrypted blobs, and auto-destructed after expiration or first download.

WeTransfer keeps files available for 7 days on the free plan with no end-to-end encryption. VaultBridge gives you configurable expiry timers, download count limits, and burn-after-read — all with AES-256 client-side encryption.

For sending confidential files online — contracts, medical records, API keys, or business documents — VaultBridge provides the security controls that WeTransfer and Dropbox simply do not offer.

Use VaultBridge for one-time delivery of sensitive files: secure document sharing for business, sharing API keys securely, private file transfer for companies, or anonymous file sharing without login.

Use traditional cloud storage for long-term collaboration where persistence and co-editing are more important than confidentiality. For everything else, encrypted temporary vaults are the safest way to share files online.
