Free. No account required.

Connection map

See every connection. Drawn for you.

As you add your assets and how they connect, the builder draws the map. Connections that cross your security perimeter show in red, so you can see straight away where the risk comes in.

Questions

Before you start.

Is it really free?

Yes. Lite costs nothing, now or later. There is no trial period and no card details are asked for.

Do I need an account?

No account required. We ask for your email address before you start, and that's it.

What happens to my answers?

Your answers stay on your device. We keep only the details you give us at the start: your email address, and your name, role and company if you add them. See our Privacy Policy.

Is it ready to submit?

It's a draft for you and your reviewer to work from. The full Artefact Builder goes on to the risk assessment, architecture and plan, and exports submission-ready Word documents.

Can I move to the full builder later?

Yes. Get in touch and we will show you the full builder on your own programme.
