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.

Offline Secure Storage (OSS) for Business

Hold Gold Copies Away from Ransomware

Ransomware encrypts everything it can reach. Your gold copies — the last line of defence — should be physically unreachable. Offline Secure Storage (OSS) makes that possible.

Why OSS

We Think This Is Hard to Ignore

Ransomware attacks have risen 105%, and the average attack costs a UK business £210,128. At Firevault, your gold copies live on hardware that physically disconnects after every sync, because the only backup ransomware cannot encrypt is one it cannot reach.

What's Going Wrong

Your backups are not safe if they're connected.

Backup Targeting

Modern ransomware specifically hunts for and encrypts backup systems first.

Cloud Backups at Risk

Cloud-connected backups are reachable — and therefore encryptable.

NAS Vulnerabilities

Network-attached storage is on the same network as the threat.

The Reality

Backups are already being encrypted.

The Scenario

It's 6am on a Monday.

Your CISO calls. Ransomware has encrypted every server, every backup, every NAS. The attackers want £2M in Bitcoin. Your insurer won't pay because your backups were network-connected. But your gold copies? They were in a Firevault vault. Physically disconnected. Untouched.

"The only backup that survived was the one they couldn't reach."

How Firevault Stops This

Write the gold copy. End the network path. Recover clean.

Your gold copies are written to dedicated RAID 1 drives inside a Firevault Bunker during an identity-verified sync window. Once the write is complete, the drives physically disconnect. No network cable. No Wi-Fi. No API. No path for ransomware to follow. When ransomware encrypts everything it can reach, your gold copy is not among them — because it is not connected to anything. When you need to recover, a physical connection is re-established, and the gold copy is intact, unencrypted, and ready.

Ransomware targets backups first — but your gold copy is on hardware that physically disconnects after every sync. There is no network path to follow
Not a cloud backup — no API to compromise, no credentials to steal, no always-on connection for ransomware to traverse
Not a NAS — your gold copies are not on the same network as the threat. They sit in a sealed Firevault Bunker with no network interface
Recovery is immediate — when ransomware encrypts everything it can reach, a physical connection to your untouched gold copy is created on your authority

Write the Clean Copy to Offline Storage

Step 1 of 3

During an identity-verified sync window, your gold copies are written to dedicated RAID 1 drives inside a Firevault Bunker. The data is committed to hardware that exists outside your network perimeter. For Storage and Enterprise tiers, automated sync runs via API or SFTP within scheduled windows.
