Secure products, built by Devsultants
Our products come from the same work as our services: secure systems for organisations whose data cannot leave the building. Each one runs entirely on hardware you control and is designed against UK National Cyber Security Centre guidance. Our AI products run from a compact desk-side system to a data-centre server with no connection to the internet, and Cold Harbour controls how third-party software reaches networks like those.

Cold Harbour
One controlled path for open-source and third-party components. Cold Harbour verifies, scans and quarantines everything it fetches, and publishes only what a named reviewer approves, with a full audit trail.

Our products grew out of client work. If they are close to what you need but not quite, we can help you design and build secure, air-gapped AI tooling of your own.
