Mergers and acquisitions generate the most commercially sensitive documents in business. Due diligence packs pass through advisors, lawyers, and consultants, each a leakage point. Cloud-based deal rooms remain network-connected and therefore reachable by attackers. A single breach can collapse a deal, trigger regulatory investigation, and expose both parties to legal liability. 02 How it plays out ## The scenario, and what physical disconnection changes. One realistic sequence of events, then the controls that break it. Scenario During a £200M acquisition, a law firm's email system is compromised. The attacker gains access to the full due diligence pack, financial models, valuation analyses, IP assessments, and draft contracts. The leaked valuations are used to undermine the buyer's negotiating position. The deal collapses, and both parties face securities investigations. Protection - Deal room documents stored on physically isolated, air-gapped media, no network path to reach them - Party-specific access controls with session logging for every document interaction - Full audit trail supporting regulatory compliance and post-completion retention - Secure handover and archival post-completion 03 The outcome ## Deal document integrity maintained 100% By storing deal-critical documents offline with Firevault OSS, both parties eliminate the risk of network-based theft during the transaction lifecycle. The deal record is preserved with provable integrity, satisfying regulatory and archival obligations. Hardware The data sits on Firevault hardware, not a shared cloud tenancy. Disconnect Offline by default. No standing network path in or out. Command Access opens on your instruction, identity checked and logged. Location Held in a Firevault Bunker. Firevault provisions the location unless you request one in writing. 04 Keep exploring ## More ways organisations use #OSS. Every use case follows the same four physical principles, applied to different data.
