Chain of custody,
built in.

For law firms and legal teams who need leak-traceable, timestamped, and revocable control over NDAs, evidence, and privileged case files.

The problem with emailing privileged documents

No chain of custody

You email an NDA. The recipient forwards it. You have no record of who accessed it or when.

Untraceable leaks

If a case file leaks, there’s no watermark to trace it back to the source. No recourse.

No time-boxed access

Disclosure obligations have windows. Email gives you no way to automatically expire access.

Permanent copies

Privileged material lands on the recipient’s device. You can’t revoke it. You can’t prove they read it.

How FileLink solves it

Leak-traceable watermarking

Every page stamped with the counterparty’s name, email, IP, and timestamp. If a privileged document leaks, you trace it to the exact viewer.

Litigation-ready access logs

Full timestamped record of every access — who opened it, when, from where, on what device. Exportable as evidence.

Expiring links for time-boxed disclosure

Set disclosure windows that automatically expire. Access closes the moment the obligation period ends.

Download-blocking for privileged material

View-only mode prevents downloads, prints, and copies. Privileged material stays in the browser — never on disk.

OTP-verified access

Every viewer must verify identity with a 6-digit OTP. No anonymous access to sensitive case files.

Chain of custody, built in

From creation to access to expiry — every step is logged. A defensible record of who saw what, and when.

We don't send copies. We stream control.

FileLink streams privileged documents to the viewer's browser — no copy ever lands on their device. When the disclosure window closes, you revoke access instantly. Zero forensic footprint. Full chain of custody.
