Find out how your defences fail before an attacker does

A cyber test range is a high-fidelity replica of your real environment. A place to attack, train, and prove your defences under genuine pressure, with zero operational risk. We design, build, and operate them for the organisations that cannot afford to find their gaps the hard way

cyber test ranges

More than just a digital twin

Our Cyber Test Range (CTR) is a high-fidelity digital twin of your real environment, enriched with the data, users, tools, and monitoring that make it behave like the genuine thing.

When something goes wrong, you rewind the clock and run it again, with no operational risk.

A range shows you three things no plan ever can:

How your tools react to an event

How your people react

How your process holds up under pressure

how it works

How we design, build and operate your custom range

We design, build, and operate bespoke ranges for training, live testing, product validation, and red team operations. Your team can rehearse against real threats in a place that is safe to break

We scope what matters

We work out which parts of your estate actually drive your risk, your training need, or your validation goal. You build only what counts.

We build your range on Stratum8

Using our own product set, we provision a high-fidelity replica of those systems, at whatever scale you need.

We train, test, and validate

Your people exercise against real threats. When something breaks, we rewind the clock and run it again, until you are ready for the real thing.

Why IT MATTERS

What CTR can do for your team

You would never train a heart surgeon on a healthy heart. A range lets you rehearse the bad day, find the gaps, and fix them, long before they cost you anything

Exercise & rehearse

So your people are ready before an incident, not during a real one

Validate products

Prove the technologies you've bought actually deliver what they claim

Train continuously

Persistent environments that stay live around the clock, so your team build skills safely

Sustain your estate

Test patches and changes before they ever reach production

Prove resilience

Validate that your systems hold up under conditions you can't simulate any other way

Trust physical & OT

Plug Operational Technology systems straight into the range alongside red team operations
