01 Why organizations choose UltimaOS

Three properties you will not find together anywhere else.

Isolation

A platform, not a tenant

Your UltimaOS platform is fully separated from every other — members, data, brand, apps, admin roles.

Accountability

Invitation-based membership

No open registration. Every account is created via an invitation and remains tied to its inviter.

Cryptography

Post-quantum by default

Internal messaging, mail, file storage, notes and tasks are end-to-end encrypted with NIST-standardized post-quantum algorithms.

02 Compliance

The points to bring to your CISO.

Every claim below is verifiable in the system's behavior and data model.

Asymmetric cryptography 100% post-quantum. ML-DSA-65 (FIPS 204) for signatures, ML-KEM-768 (FIPS 203) for key encapsulation. Zero RSA. Zero elliptic-curve.
Symmetric encryption XChaCha20-Poly1305 (RFC 8439) with HKDF-SHA256 key derivation.
End-to-end encrypted Chat, attachments, mail, files (names included), notes, tasks, documents, spreadsheets, presentations, boards.
Credentials No password database. Keys derived in the browser, server stores public keys only.
Sessions & tracking Zero cookies. Browser storage is wiped on every page load.
