What is secure file storage?
It is storage designed so that confidential files stay confidential: restricted access, verified integrity, controlled locations and a reliable path to retrieve the original.
Secure file storage without the clutter.
Store, organise, archive and retrieve confidential files in a private vault designed for importance rather than volume.
What does Citadel store?
Anything you would not want copied: contracts, financial records, valuations, case files, designs, credentials, private keys, board packs and personal records.
How do files get in?
Drag them onto any screen in Citadel. Folders keep their structure, progress is shown while you keep working, and every file is verified once stored.
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.
Built for the files that matter, not all of them.
Most file storage is sized for everyday work: thousands of documents moving between many people every day. Citadel is sized for importance. A small number of files, protected far more carefully than the rest.
That focus is what allows the interface to stay quiet. No permissions matrix, no shared-with-me, no link settings to get wrong.
Desktop habits, vault discipline.
Select with a click, open with a double-click, right-click for everything else: rename, move, copy, favourite, archive, download or delete. Folders can be dragged. Search finds what you need immediately.
Deleted files go to Trash rather than disappearing, and archived files stay protected but out of the way.
Questions people ask
- Can I organise files in folders?
- Yes, with nested folders, favourites and an archive. Uploaded folder structures are preserved exactly.
- Can I download a whole folder?
- Yes. Folders are assembled and streamed back to you as a single download.
- Is there sharing?
- No. Citadel is a vault, not a collaboration platform. Files leave only when you retrieve them.
