Managing files with clients is a security vulnerability for many businesses. Sending sensitive files via email or public links exposes you to data leakage risks. The solution is a dedicated document portal that provides an isolated environment for every client.
Account Isolation and Data Security
The fundamental principle is isolation. A client must only see their own files. Avoid using permanent public links; instead, use temporary links that automatically expire after a set time. This minimizes the risk of unauthorized access.
Upload Constraints and Version Control
Files uploaded by clients must be subject to strict constraints regarding size and type. Furthermore, the system should support versioning. If a client uploads a new file, the old version should remain available for review until the new one is formally approved.
Review and Approval Workflow
The system should include an 'Approval' function. It is not enough for a client to just upload a file; the responsible employee must review the file and change its status to 'Approved', preventing confusion regarding which version is the final one.
Observable Acceptance Criteria
- A permission system that prevents Client X from accessing Client Y's files.
- An activity log showing who uploaded or downloaded any file.
- Download links that automatically expire.
Practical FAQs
Q: Can I allow multiple people to access the same file? A: Yes, you can set up shared permissions, but these must be limited and strictly monitored. Q: Is the portal a substitute for public cloud storage? A: A portal is a workflow and access interface that may use cloud storage underneath. Compare existing tools with custom development against isolation, approval and integration needs; the portal does not remove storage and recovery requirements.

A practical acceptance example
Imagine a client uploading a document for their project. Verify another client's user cannot download it even with the URL or record ID. Revoke access, repeat the test and review download-link expiry. Membership, versions, approvals and file sizes determine the scope beyond a single upload screen.
