Ranges and replicas that you can rebuild exactly, on networks you control.
Coldlight builds each environment from a defined architecture or specification. It runs contained, with instrumentation for repeatable and auditable assessment. Rebuild it exactly, as often as you need.
Environments move with the work: from hosted, to jurisdiction-controlled infrastructure, to networks with no outside connection.
Customer-selected software, security products, models and agents can be included. Autarchy does not assume a standing inventory of proprietary software.
What you can test
- 01Run the same scenario against different tools, teams or agents, and compare the results.
- 02Rehearse an operation against a replica of the target environment.
- 03Validate in-house or supplier agents against controlled cyber scenarios.
- 04Introduce customer-selected proprietary or commercial software for a scenario.
- 05Rehearse the defence and recovery of base and platform OT.

What the twin can represent
01
Enterprise
Networks, identity and services, built from your architecture.

03
Base infrastructure
Industrial control systems for power, water and buildings.

Fidelity
Level 1
Containers
Cost-efficient representations of hosts, services and networks.
Level 2
Virtual machines
The real operating systems and software that your systems run.
Level 3
Appliances
Real or virtual appliances, where the test depends on them.
Synthetic users, scripted or live adversary activity, and defensive tools or agents can run in the same environment.
Third-party software can run under licences you already hold, or we can arrange it as a cost of the engagement.
Every environment
Contained by default
What runs inside an environment stays inside it unless you decide otherwise.
Rebuilt exactly
Environments are defined as code. Reset one, change one thing and run the test again.
A record of every run
Every run leaves a record you can review. Compare results across runs and configurations.
The fidelity each test needs
Use lightweight representations where they are enough, and real software and appliances where the test needs them.
Technology-neutral
Open-source, commercial, proprietary and customer-built technology can all be included.
Open formats
Environment definitions use an open, portable specification, so your work is not locked to us.
Where it runs
Hosted
Coldlight as a service. Hosted environments can run in Canada and other jurisdictions.
On-premises
Coldlight inside your own boundary, on infrastructure you control.
Air-gapped
Coldlight on networks with no outside connection.
We can also operate Coldlight for you, and help design environments, deliver exercises and support evaluations.
