Indemnification Warranty
Backed by Lloyd's of London.

What makes Citadel different?
Encryption protects data with mathematics and keys. Citadel adds a physics-based protection layer, reducing and separating your data so no single storage location holds a whole, readable file.
What is Citadel designed to protect?
Crown-jewel data: financial records, intellectual property, board documents, legal files, contracts, AI models, source code, strategic plans, customer information, private keys and family records.
Drag. Drop. Store. Retrieve.
Simple storage. Protected by physics.
Drag files into your vault and they are protected the moment they arrive. Organise them in folders, archive what you no longer touch, search the whole vault in a second and retrieve the original whenever you need it.
There is nothing to configure and nothing to learn. The more important the information, the simpler the experience should be.
Encryption is not the only answer.
Encryption protects data with mathematics and keys. Citadel adds a physics-based protection layer designed around a different security model: your data is reduced, separated into fragments that carry no independent meaning and distributed across the storage environments you allow.
Encryption compared with physics-based protectionStolen today, opened later
Encrypted data taken now is being stored until better computing can open it. Your most sensitive files are still sensitive in ten years.
The breach is always internal first
Most crown-jewel exposure comes through an account that was allowed in — not a wall that was broken down.
One copy, one lock, one mistake
A workplace drive keeps a whole, readable file behind a single credential. That is a single point of total loss.
What goes inside
Protect your crown jewels.
Financial records. Intellectual property. Board documents. Legal files and contracts. AI models and source code. Strategic plans. Customer information. Family records. And digital assets — bitcoin keys and recovery phrases, where a single glimpse is a total loss.

Built by Secured2
Quantum-Secure® storage.
Citadel is powered by Secured2's Quantum-Secure® storage architecture and its physical security layer. Files are reduced, separated and distributed, so there is no single copy to steal and no master key to compel — and reassembly requires proof of who you are.

How physics-based protection works Deployed and managed
Your vault. Your storage. Your data.
Citadel runs in the cloud, across a hybrid arrangement, or entirely within infrastructure you control — and every client is set up and looked after by a named person, not a ticket queue.
Cloud
Protect information within your cloud strategy without changing how leaders reach Citadel.
Hybrid
Bring cloud and private infrastructure together in one deliberate storage approach.
Local
Keep protected information within infrastructure your organisation directly controls.
A different class of storage
Not another company drive.
Dropbox is where you keep your files. Citadel is where you keep the files you cannot afford to lose. No sharing, no guests, no links — because every one of those is a way out.
