Who is this document for?
- Administrator: Configure the document sharing via link feature for the entire workspace.
- Approver: Review sharing requests and manage document access permissions.
Feature Setup (Administrator)
This operation only needs to be performed once before deploying to employees.Step 1: Block unmanaged file transfers
To ensure data is only shared via the system link, Administrators need to enable the file transfer blocking feature. Go to: Device Management → Data Protection → File Transfer Blocking → Toggle onBlock file transfer.

Step 2: Configure Sharing Management Mode
Administrators choose one of two control mechanisms:- Free Mode: Employees actively create links. Administrators perform post-audit via Logs (tracking identity, time, and number of visits).
- Approval Mode: Links only become effective after the employee’s request is approved by an Approver.
Request Review (Approver)
Applicable when the Administrator has enabled Approval Mode.
Step 1: Create a Security Key (first-time setup)
The Security Key is a unique password for each account, used to decrypt document content when Previewing or downloading files directly from the system. Only the key owner can view the content - no other account in the same workspace can view it on their behalf.The Security Key is linked to the user account and does not change across Workspaces.

Step 2: Receive notifications and view pending requests
When an employee creates a sharing request, the Approver will receive an Email notification.Step 3: Preview the document before approving
Before granting permission, Approvers should preview the document content to ensure no sensitive information is being shared externally.The Security Key only needs to be entered once per session. After that, you can Preview other files without re-entering the key.
