Is secure cloud storage the same as encrypted cloud storage?

Not quite. Encrypted cloud storage describes one protection method. Secure cloud storage is the broader category, covering how data is protected, who can reach it, how integrity is proven and how it is recovered.

Can Citadel store very large files?

Yes. Uploads are chunked and resumable, so large archives, datasets and media transfer reliably and can continue after an interruption.

What happens if a storage provider has an outage?

Because data is distributed rather than parked in one place, the loss of a single location does not mean the loss of your file.

Secure cloud storage

Secure cloud storage for the files you cannot afford to lose.

Citadel by Secured2 is premium secure cloud storage built around one job: keeping your most important data safe, available and entirely yours.

What is secure cloud storage?

Secure cloud storage keeps files on managed infrastructure while limiting who can reach them, proving they have not been altered, and keeping them recoverable. Most services deliver this with encryption keys and access controls.

How is Citadel different?

Citadel adds Secured2's physics-based Quantum-Secure® protection to the data itself. Files are reduced and separated before they are distributed, so no single storage location holds a whole, readable file.

Who is it for?

Organisations and individuals protecting crown-jewel data: board papers, financial records, intellectual property, legal matters, source code, AI models and private keys.

Simple storage. Protected by physics.

Conventional cloud storage protects data with mathematics: a key is generated, the file is scrambled, and everything depends on that key staying secret and that algorithm staying unbroken.

Citadel does not ask you to bet on either. Files are compressed, stripped of recoverable structure, separated into fragments that carry no independent meaning, and distributed across the storage environments you allow. A fragment obtained by an attacker is not a weakened copy of your file. It is nothing.

A vault, not a workspace.

Citadel is deliberately not a collaboration tool. There is no sharing, no guest access, no comment threads and no public links, because every one of those is a route out of the vault.

What remains is fast and familiar: drag files in, organise them in folders, search, favourite, archive, retrieve. The experience people expect from modern cloud storage, with the restraint that critical data deserves.
