Who Citadel is for
For the information a business cannot afford to expose.
Different industries, one pattern: a small set of files whose loss, theft or exposure would materially change the organisation.
Legal
Matters where a leak is not an IT incident — it is the case.
- Privileged counsel memoranda
- Litigation and settlement files
- Sealed client evidence
Technology
The things that are the company, not just records of it.
- Source-code archives and signing material
- Model weights and training sets
- Unfiled patents and trade secrets
Medical & life sciences
Patient and research data with regulatory weight and decade-long sensitivity.
- Clinical trial datasets
- Research and formulation IP
- Regulated patient archives
Boards & governance
Material information before it becomes public information.
- Board books and minutes
- M&A targets and diligence
- Executive and succession files
Family offices & principals
Private wealth where exposure is personal, not just commercial.
- Trust and estate documents
- Identity and passport records
- Private holdings and valuations
Industrial & critical infrastructure
Designs and operational detail that adversaries actively hunt.
- Plant schematics and control designs
- Supplier and process specifications
- Incident and resilience plans
Digital assets
Keys and recovery material that cannot be reissued if they are lost or seen once.
- Bitcoin and wallet seed phrases
- Treasury multisig recovery material
- Exchange and custody credentials
A special case
Bitcoin keys and recovery phrases.
A seed phrase is the rare piece of data where one glimpse is total loss and one misplaced copy is total loss too. Printing it is fragile. Storing it in a password manager puts it behind a single secret.
In Citadel it is shredded into fragments held across separate environments, retrievable only by your authenticated identity — so there is no single copy to find, and no single copy to lose.
Nothing readable at rest
No location holds a usable fragment.
No key to compel
Protection is structural, not a stored secret.
Survives a lost device
Recovery does not depend on one machine.
Verified on retrieval
You get back exactly what you stored.
Citadel by Secured2
If losing it would change your company, it belongs in Citadel.
Most clients start with fewer than a hundred files. Those are the hundred that matter.
