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.

OSS for Industry

Offline Secure Storage for Government

Government and public bodies handle some of the most sensitive data in existence. Offline Secure Storage (OSS) provides physical disconnection for classified and citizen data.

We Think This Is Hard to Ignore

The MOD disclosed 500,000 service personnel records exposed through a compromised payroll provider in 2024. At Firevault, sovereign data lives on hardware with no network connection, because national security cannot depend on third-party infrastructure.

How Firevault Stops This

Remove sovereign data from every system attackers can reach.

Classified records, citizen data, and critical government files are taken off connected infrastructure and written to dedicated RAID 1 drives inside a Firevault Bunker. Those drives have no internet connection. No IP address. No API. When SC/DV-cleared personnel need access, a physical connection is created after identity verification. When the session ends, the drives disconnect.
