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.

We Think This Is Hard to Ignore

Allen and Overy disclosed that ransomware attackers accessed confidential client matter files stored on always-connected firm systems. At Firevault, privileged legal records live on hardware that physically disconnects between sessions, because legal privilege ends where network exposure begins.

Industry Risks

Why law firms are prime targets.

Client Privilege

Privileged communications and case files are high-value targets for cyber criminals.

SRA Compliance

The SRA mandates appropriate measures to protect client confidentiality.

Opposing Party Access

In litigation, compromised data can be exploited by opposing parties.

The Reality

This is already happening in legal services.

How Firevault Stops This

Remove privileged files from every system attackers can reach.

Client files, case documents, and privileged communications are taken off firm networks and written to dedicated RAID 1 drives inside a Firevault Bunker. Those drives have no internet connection. No IP address. No API. When authorised counsel need access, a physical connection is created after identity verification. When the session ends, the drives disconnect.

Client files removed from firm networks and placed on hardware with no network connection. Privilege cannot be waived if the data was never reachable
Matter-specific access controls with identity verification. Stolen credentials cannot unlock physically disconnected hardware
Full audit trail satisfying SRA and ICO requirements. Every file access is logged with chain-of-custody integrity
Supports GDPR Article 32 appropriate technical measures through the strongest measure available — physical disconnection

Take Privileged Files Off Firm Systems

Step 1 of 3

Privileged communications, case files, and client documents are taken off firm networks and written to physically disconnected RAID 1 drives inside a Firevault Bunker. No cloud. No shared portal. No attack surface.
