For supported PDF files, bestCoffer can keep expiry and opening checks connected to the controlled workflow after download. Authorized teams can remotely revoke opening rights; this does not physically delete the copy from the recipient device.
Why controlled PDF access matters
Many confidential workflows try to avoid downloads. When a reviewer needs a supported PDF, the workflow should define who may download it, when opening rights expire, and when access should be revoked.
Control model
| Control | Purpose | Risk reduced |
|---|---|---|
| Opening permission check | Verifies whether a user can still open the file. | Former reviewer keeps access after removal. |
| Expiry | Limits access after a period or project phase. | Old files remain active indefinitely. |
| Watermarking | Links use to a user or project. | Unattributed screenshots or photos. |
| Audit trail | Records relevant activity. | No evidence after download. |
| Revocation | Removes opening rights when needed. | Access continues after the mandate ends. |
Implementation checklist
- Define which file types can be downloaded.
- Apply stricter controls to HR, finance, IP, legal, and customer files.
- Separate original and redacted versions by permission.
- Use watermarks for sensitive exports.
- Review access after each deal phase.
- Close or revoke access when the project ends.
