Cosign vs SharePoint: start with your workflow.
Would a separate room make external access, diligence questions, and document activity easier to manage?
Use these checkpoints to assess both products with your own documents. This is a workflow guide, not a claim that every feature or service is equivalent.
| Workflow | Cosign early access | Check with SharePoint |
|---|---|---|
| Document organisation | Room documents, folders, and versions | Test your folder structure, file types, and volume. |
| Recipient access | Private links, document permissions, passwords, and expiry | Confirm recipient roles, authentication, and access revocation. |
| Review protection | Download controls and watermarks | Validate your required controls with actual recipients. |
| Diligence coordination | Document requests, tasks, and Q&A | Check assignment, reporting, and review responsibilities. |
| Activity records | Room audit events and engagement tracking | Confirm required retention and export formats. |
Watermarks and browser controls discourage copying; they cannot prevent screenshots or cameras.

2. Check recipient access
Set permissions, open a test recipient link, and verify the visible documents and download rules.
3. Follow the review
Ask a question, request a document, and check the activity record before inviting your deal team.
Questions about switching
Can I use Cosign as a SharePoint alternative?
Create a dedicated review workflow with recipient links, document permissions, and room activity. Cosign is in early access. Validate the complete workflow with representative documents and recipients before using it for a live transaction.
How do I move from SharePoint?
Export the files you are authorised to move, create a room, upload and organise the documents, then recreate recipient permissions. Test access before sending new links. Existing links, audit history, and permissions are not automatically imported.
What should I check before choosing a data room?
Confirm your required security certifications, data residency, support commitments, file limits, and compliance requirements directly. Do not assume feature or contractual parity.
How much does Cosign cost?
