Secure Data Rooms. Zero Data Room Tax.
M&A, legal proceedings, board materials - all within your Microsoft 365 tenant. No per-user fees. Full sovereignty.
Traditional VDRs Are Broken
Per-user pricing that explodes with deal complexity. Data extracted to third-party servers. Separate logins that frustrate guests. Limited governance once the deal closes. Govern 365 Vault is different.
How It Works
Create the room
Backed by SharePoint libraries you already manage. Add folders, apply sensitivity labels.
Invite guests
Send invite links — no O365 license required. OTP authenticates at first access.
Guests browse securely
View documents with watermarking. Download only where permitted. Every action logged.
Audit and archive
Export logs, heatmaps, evidence. Archive when the deal closes — tamper-evident packages.
Manage Data Rooms in SharePoint
Configure rooms, set permissions, and invite guests — all from within your existing SharePoint site. No separate admin portal. Native Microsoft 365 experience.
