What is quantum-secure storage?
Storage designed so that advances in computing — including quantum computing — do not make previously protected data readable.
Quantum-Secure® storage
Quantum-Secure® storage for data with a long life.
If your data still matters in ten years, it has to survive ten years of better computers. Citadel is built for that horizon.
Is quantum-resistant the same thing?
Quantum-resistant usually describes new mathematics intended to withstand quantum attack. Citadel takes a different route: remove the coherent data an attacker would need in the first place.
Why act now?
Because data is being collected today and opened later. Protection applied after the theft is too late.
The problem is time, not the algorithm.
Every encryption standard has a shelf life. The question is never whether it will be replaced, only whether the replacement arrives before your data is opened.
Board papers, patent filings, M&A material, medical records and private keys are all sensitive far beyond a typical algorithm's comfortable lifetime.
Quantum-secure® authentication too.
Protecting the data is only half the job. Access to Citadel is proven with a private code bound to your identity, so a stolen password alone can never open the vault.
Set-up takes a minute with any standard authenticator app, and the instructions are in the product.
Questions people ask
- Does this require special hardware?
- No. Citadel runs in the browser and works with ordinary authenticator apps.
- Is Quantum-Secure® a Secured2 trademark?
- Yes. Quantum-Secure® is Secured2's registered mark for its physics-based protection technology.
- What if quantum computing arrives sooner than expected?
- The protection model does not change. Fragments distributed across environments carry no independent meaning regardless of available computing power.
