A platform, not a tenant
Your UltimaOS platform is fully separated from every other — members, data, brand, apps, admin roles.
UltimaOS gives your organization an isolated, private platform — messaging, mail, storage, documents, boards, calendar — where the most sensitive data is end-to-end encrypted with NIST-standardized post-quantum cryptography.
Your UltimaOS platform is fully separated from every other — members, data, brand, apps, admin roles.
No open registration. Every account is created via an invitation and remains tied to its inviter.
Internal messaging, mail, file storage, notes and tasks are end-to-end encrypted with NIST-standardized post-quantum algorithms.
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. |
| Jurisdiction | Built and operated in the European Union. GDPR compliant by architecture. |
Free during the early access phase; transparent pricing for commercial platforms afterwards.
