The problem

Traditional VDRs force you to duplicate, migrate and pay for storage twice.

Every transaction kicks off the same painful cycle: re-upload thousands of files, re-permission them, retrain users, and reconcile changes between systems. Meanwhile your source of truth keeps moving in SharePoint.

  • Weeks of setup before the deal can even start
  • Document drift between the VDR and your live repository
  • Additional storage and licensing costs per deal
  • Sensitive files copied to a third-party environment

  • Zero document migration — files stay in place
  • Granular permissions layered over native folder structure
  • Stand up a workspace in hours, not weeks
  • Revoke access globally with one click
