What is offline secure storage?

Offline secure storage (OSS) is a data protection method where data is physically disconnected from the internet when not in use. Unlike cloud storage, data stored offline has zero remote attack surface — it cannot be hacked, ransomed or accessed remotely because it is not connected to any network. Firevault provides this through hardware-encrypted vaults that are physically isolated.

How does Firevault protect against ransomware?

Firevault protects against ransomware by physically disconnecting your data from the internet. Ransomware can only encrypt data it can reach over a network. When your data is stored offline in a Firevault, ransomware attacks cannot reach it. Even if your entire network is compromised, your offline vault remains untouched and intact.

How much does Firevault cost?

Firevault Vault starts from £75 per month (inc VAT) for individuals. Business Storage starts from £360 per month (inc VAT). Enterprise Platform pricing is available on request. All plans include hardware encryption, identity verification, and physical disconnection by default.

Who is Firevault designed for?

Firevault is designed for individuals protecting passports, wills and crypto keys; professionals such as solicitors, accountants and consultants protecting client data; SMEs and businesses protecting crown jewel data; and regulated industries including healthcare, financial services and legal sectors requiring offline backup for compliance with GDPR, NIS2, DORA and FCA regulations.

Is Firevault GDPR compliant?

Yes. Firevault is designed to support GDPR compliance by keeping sensitive personal data physically isolated and offline. Physical disconnection ensures data is not exposed to network-based attacks, supports data minimisation principles, and provides an audit trail of access. Firevault is also designed to support NIS2, DORA, FCA and SRA compliance requirements.

What is a physical air gap?

A physical air gap is a security measure where a computer or storage device is completely isolated from the internet and all unsecured networks. Unlike a logical or software air gap, a physical air gap cannot be bridged remotely. Firevault uses a Layer 1 physical air gap — your data is stored on hardware that is physically disconnected from any network when not in active use.

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.

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.

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.
