document rights management
Send the document. Keep the control.
Vaultline replaces attachments with policy-bound links. The PDF stays encrypted on your server; recipients get a watermarked, view-only window that you can expire, limit to specific devices, or revoke at any moment.

Encrypted at rest
Every file is sealed with its own AES-256 key. The original bytes never leave the server.
View only
Pages are delivered one at a time. No download, no print, no copy, no text layer to scrape.
Dynamic watermark
Recipient email, timestamp and IP are burned into every page as it is served.
Device limits
Each recipient is bound to a fixed number of registered devices.
Expiry
Set a date and the link stops working, wherever it has been forwarded.
Instant revoke
One click ends access on the very next page request.
Audit trail
Opens, page views, denials, IP, browser, device and timestamp.
REST API
Upload, grant, revoke and export logs programmatically with scoped keys.
Honest limit: no browser viewer can stop a camera pointed at the screen. Watermarking and the audit trail make a leak traceable to one recipient, one device and one moment.
