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.
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.
A mathematical defence weakens as computing improves. A location that contains no meaningful data does not weaken.
It is Secured2's core technology, already established in its Quantum-Secure® storage architecture, and Citadel brings it into a simple storage experience.
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.
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.
