No hand-waving.
Just the data path.
Exactly where the model lives, how data moves, and who holds the keys — all inside a perimeter you control. No black boxes.
Four stages, one sealed path.
ENCRYPT
Sealed before it leaves.
The instant a document leaves your device, it is encrypted into cipher blocks. Nothing readable ever travels the wire.
IN TRANSIT
Behind your own TLS.
Traffic to your isolated workspace runs behind TLS 1.3 termination you control. Intercept the stream and you get noise — the keys never leave your boundary.
AT REST
Docked, isolated, encrypted.
Data lands in a workspace dedicated to you — encrypted at rest with a key you supply, no shared tenancy, in a region you control.
ROUND TRIP
Returned, never retained.
Results travel back the same sealed path. Diana keeps nothing it does not need, and never trains on what it sees.
Specialist parts, one system.
Retrieval layer
Reads your sources and grounds every answer in the exact file and page — no hallucinated citations.
Reasoning layer
Specialist models plan, draft and check the work — each an expert in its domain, orchestrated as one.
Sovereign layer
Everything runs in infrastructure you control — on-prem or a dedicated sovereign cloud. Your perimeter, your rules.
It comes back. Nothing stays behind.
Results return on the same encrypted path they left on. Diana retains only what your workspace keeps — and never uses any of it to train a model.
Architecture you
can audit.
No black boxes. Every stage of the path is documented, logged and open to your security team.
