# Regions

Your organization belongs to a region — **EU** or **US** — shown in the header on the
Overview screen.

## What it determines

Which Gateway your developers' tools talk to, and where your audit data, findings and any
captured prompt content are stored.

The Endpoint Suite resolves the right Gateway automatically when a device registers. There
is a compiled-in fallback, but it is only used if the backend did not supply one — you do
not need to configure regional hostnames per machine.

## Where the boundary is not

Two honest caveats.

**AI providers are outside it.** When a request leaves the Gateway for Anthropic or
OpenAI, it goes wherever that provider processes it. Sentilai governs and records the
request in your region; it cannot make a US provider process data in the EU.

**Azure OpenAI keys carry their own region**, which you set yourself. If it does not match
your organization's region, the console shows a warning badge on the key — it warns rather
than blocks, because it is sometimes deliberate, but it should never be accidental.

## Choosing

Regions are set when your organization is created. Moving between them is not
self-service — open a ticket and we will talk through what is involved.
