FileLink vs. DocSend
DocSend and FileLink are closer on core security mechanics than they first appear — DocSend's Advanced plan includes NDA gating and dynamic watermarking too. The real differences are verification method, plan-level access to those features, and what each product is built for. FileLink includes NDA gating and watermarking on every plan. DocSend gates them behind Advanced.

Why this matters
DocSend 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.
