Sentinel EMR, in clinical practice

I. What we make

SentinelIntelligence, kept in‑house.

An AI appliance that runs language models and document search on your own premises. Your team reaches it through your network; what connects to the outside world is a decision you make with us, not a default.

II. How we work

Privacy is where
we start.

Custodia began in data privacy and AI governance. Sentinel is what that work taught us to build.

i.

Keep sensitive work close.

Client files, records and internal knowledge stay on hardware you own, inside your own walls.

ii.

Run the AI entirely on site.

Sentinel’s models run on the appliance itself, not a cloud AI service. Prompts and documents never reach an AI provider, and it keeps working offline once set up.

iii.

Build for the people doing the work.

Our first application came from a working clinical practice. We start from real workflows, not from a model looking for a use.

III. About

A small company
with a narrow focus.

Custodia Privacy Consulting SAGL is based in Switzerland. We design, configure and support Sentinel appliances, and work directly with each organisation that runs one.
