What is physics-based security?
An approach that protects information by controlling what physically exists in any one place, rather than relying only on the difficulty of a mathematical problem.
Physics-based data protection.
Mathematics can be outpaced. Citadel is built on what is physically present in a location — and what is not.
Why does that matter?
A mathematical defence weakens as computing improves. A location that contains no meaningful data does not weaken.
Is this proven technology?
It is Secured2's core technology, already established in its Quantum-Secure® storage architecture, and Citadel brings it into a simple storage experience.
Every Citadel subscription protects more than storage.
Citadel is priced for the people who use it and the work they do. The service connects identity, networking, transport, protected data, recovery and business continuity in one architecture.
Identity
Quantum-Secure® authentication designed to reduce dependence on traditional key-based access.
Network
Quantum-Secure® private networking extends protection beyond the storage environment.
Transport
ParticleMesh™ protects data as it moves between people, applications, clouds and infrastructure.
Data
Secured2 protection is applied to the data itself, beyond conventional encryption at rest.
Resilience
Multi-location redundancy, recovery and business continuity reduce dependence on any single system.
Risk
Eligible deployments can include contractual cyber-risk indemnification backed by a Lloyd's of London insurance policy.*
* Insurance, indemnification, coverage limits, exclusions, eligibility and availability are subject to the applicable policy and contractual terms.
Reduce, shred, distribute.
A file is first reduced: compressed and stripped of recoverable structure. It is then separated into fragments that carry no independent meaning — not weakened copies, not partial views.
Those fragments are distributed across separate storage environments. Compromising one yields nothing, and losing one does not lose the file.
What an attacker actually finds.
Breaching any single location does not produce a document, an image, a dataset or a key. It produces material that cannot be reassembled into anything without the rest of the mesh and an authenticated identity.
That is the difference between a defence that must hold and an outcome that does not depend on holding.
Questions people ask
- Does this slow uploads down?
- No. Protection happens as part of the transfer, with progress shown while you carry on working.
- Is the original ever reconstructed in storage?
- Reassembly happens only for your authenticated retrieval, and the result is checksum-verified against what you stored.
- Where can fragments be stored?
- Across the cloud, hybrid or local environments you approve as part of your configuration.
