Data Room

Open When Needed. Sealed The Rest Of The Time.

Cloud data rooms stay open long after deals close. A Firevault Data Room is offline by default. You open it for a defined window, share with named parties, then physically disconnect it again.

Why OSS

Data Room

Your most sensitive data deserves protection that goes beyond software. Firevault provides the only storage that is physically unreachable by design.

Why Cloud Data Rooms Fail

Always-on data rooms are always at risk.

Always-On Exposure

Traditional VDRs sit on the public internet 24/7. Every confidential document is permanently reachable, indexable, and a target.

Third Party Risk

Bidders, advisers and lawyers all download to their own devices. One compromised laptop leaks the entire deal book.

Lingering Access

Sessions, links and exports stay live months after a deal completes. Old data rooms become quiet breaches waiting to happen.

The Reality

This is already happening to deal data.

M&S: DragonForce Ransomware via Compromised Third Party

Attackers gained access to M&S systems through a compromised third-party provider and encrypted core operational data. In a deal context, the entire data room would have been exfiltrated.

Capita: £14M Fine After Client Data of 6 Million People Exposed

Capita manages outsourced deal and client data for hundreds of organisations. The ICO fined the company £14 million after hackers accessed personal data across multiple client engagements.

Harrods: Supplier Breach Exposed 430,000 Customer Records

Hackers stole customer data from Harrods via a compromised supplier, the second cyber attack to hit the retailer in the same year. Third-party data rooms face identical supply chain risk.

BBC News, September 2025

The Scenario

The data room that never closed.

An acquisition completes. Six months later, a junior at a losing bidder still has the share link. Their laptop is compromised. The full data room, financials, customer contracts, IP, is exfiltrated and posted on a leak site. With a Firevault Data Room, that link would have been dead the moment the access window closed and the vault physically disconnected.

"A data room should be a room you can lock, and walk away from."

The OSS Data Room

Open the room. Close the room. Disconnect.

Your Data Room lives inside a physically disconnected vault. Open it for a defined access window, grant named parties identity-locked entry, then re-seal and disconnect when the window closes. Nothing stays exposed by default.

  • Offline by default, physically disconnected from all networks between sessions
  • On-demand access windows scheduled per deal, per phase, per party
  • Full audit trail of every file viewed, by whom, and when
  • Automatic re-seal: when the window closes, the room disconnects again

Take Deal Files Off Cloud VDRs

Step 1 of 3

Deal files, financials, and due diligence documents are taken off cloud VDRs and written to physically disconnected RAID 1 drives inside a Firevault Bunker. No always-on portal. No lingering share links. No attack surface.
