FileLink vs. Dropbox
Dropbox is a general-purpose file storage and sync tool. It is excellent for collaboration on working files — and a poor fit for sharing documents where a leak means a breached NDA, a leaked board pack, or a compromised M&A process. Dropbox summarizes your files with AI, allows downloads by default, and does not verify recipient identity. FileLink was built for the files you cannot afford to have leak.

Why this matters
Dropbox is a capable tool for what it does. But if you are sharing files where a leak means a breached NDA, a leaked board pack, or a compromised due diligence process, the gaps below are the difference between control and exposure.
FileLink was built on a different principle: no AI model, no LLM, and no third-party plugin ever touches your files. Identity-verified access, custom NDAs, a secure in-browser viewer with download and print controls, and a full audit trail — all without installing anything.
