Document security
Undersign provides controls to help protect documents and signing requests throughout the signing process, from upload through completion and download.
Access and signing controls
Access to documents is controlled through the Undersign account and the signing request itself.
| Area | How it works |
|---|---|
| Account access | Documents and signing requests in your workspace are available to authorised account users. |
| Signing links | Remote signers access their signing request through the secure link provided to them. |
| Field visibility | When multiple signers are involved, field visibility can be configured to control whether signers can see values entered by other signers. |
| Signing order | Sequential signing can be enabled when signers need to complete the request in a specific order. |
| In-person signing | In-person requests allow the designated signer to complete the signing process directly from the signing interface. |
Completed documents
When a signing request is completed, Undersign provides the signed documents together with a Completion Certificate containing the signing and document information recorded during the process.
The certificate includes details such as signer information, timestamps, signing activity, IP addresses where recorded, audit trail events, and a SHA-256 hash for each document. This provides a convenient record for reviewing and verifying the completed signing request.
See Completion Certificates for details.
Download options
Completed signing requests provide three download options:
- All Signed Documents: download the completed signed documents.
- Certificate Only: download the Completion Certificate separately.
- Docs with Certificate: download the signed documents together with the certificate.
This allows you to retain the signed documents and their completion records in the format appropriate for your workflow.
Document lifecycle
Documents can be managed through the available document statuses: Sent, Completed, and Declined. Completed signing requests can be viewed from Completed Docs, where signed documents and their associated completion information are available.
Avoid claiming encryption, cryptographic hash chains, tamper-proof sealing, configurable retention, or permanent-deletion behavior unless those capabilities are explicitly documented and verified for your Undersign deployment.
