How it works

The data stays in. The research gets done.

Researchers bring their tools to the data, each project in its own isolated workspace. Data goes in and out only when approved by an authorised person.

1. Workspace

Each project gets its own secure workspace.

2. Import

Data enters only once access is approved.

3. Analysis

Work with your usual tools. The data never leaves the workspace.

4. Export

Results leave only once they’re reviewed and approved.
