How do I put files in?
Drag them onto any screen in Citadel, or browse for them. Folder structures are preserved and large uploads resume if interrupted.
Drag. Drop. Store. Retrieve.
Citadel is deliberately simple to use, and deliberately uncompromising underneath.
What happens to a file?
It is reduced, separated into fragments with no independent meaning, and distributed across the storage environments you allow.
How do I get it back?
Download it. Fragments are reassembled for your authenticated account and verified against the checksum recorded when you stored it.
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.
Everything you can do.
Organise files into nested folders. Switch between list and grid. Select, open, rename, move, copy, favourite, archive, download or delete. Search across the vault. Review your private activity history.
Storage shows what you have used, what remains and where your data is held, in plain numbers.
What you will not find.
No sharing, no links, no guests, no comments, no collaboration features and no social surface. Every one of those is a way for data to leave, and Citadel exists to keep it in.
That restraint is the product, not a missing feature.
Questions people ask
- Do I need to install anything?
- No. Citadel runs in the browser.
- Is there a second authentication step?
- Yes, a private code you set up with any standard authenticator app. We strongly recommend enabling it.
- Can I scale usage later?
- Yes. Add people or raise your usage level as your organisation grows.
