The cheapest
hardware,
no hardware
Scalable Cyber builds hardware-accurate digital twin emulations (DTEs) of complex embedded products: incorporating processors, peripherals, sensors, RF, and physics inputs. We let your team and your AI agents integrate, validate, develop, and rehearse against true device behavior before anything touches hardware. Letting you move fast, without breaking things.
The Problem
AI made embedded code cheap.
It did not make testing it cheap.
AI agents excel at writing software projects, not so much for hardware. The slower the test and iteration loop, the more accuracy drops and the worse the performance, and product quality gets. Accurate embedded firmware is hard to validate, the thing you validate against is still a physical unit: something that is scarce, shared across teams, and often something that becomes the bottleneck between a build that works and a build you can ship.
The tools you already trust don't close the gap. Multi-physics simulation tells you the environment behaves. Digital-twin and state-machine validation tells you the logic is sound. Unit tests tell you the code runs. None of them tells you the software behaves correctly on the real hardware, and nothing grounds all three against a single model of the device.
Scalable Cyber
From model to validated build,
in one loop.
The Scalable Cyber platform makes the software believe it's running on the actual hardware, in a real environment. Except you control time, the processor, and every sensor on board. Physics, radio, remote hardware, and remote controllers wire directly into the loop.
You won't need to build the emulators by hand. You bring your production code and product context; our platform generates the emulation, tests its own behavior, and asks you only where it needs a decision. The result is a digital environment your whole team (and agents!) can develop and validate against. You simply tell the system when to run the DTEs, and how to communicate with them.

Emulation building blocks already exist - QEMU, Styx, Renode, and others - and our own team has spent years contributing to projects like them. We need a new approach: one that bottom-up composes a hardware-accurate model of your product and keeps your AI agents grounded in its real behavior as they write, not just after.
That's our Digital Twin Emulators.
How It Works
You bring the system.
Scalable Cyber builds the emulation and hands you the steering wheel.
- 1
Bring your system in
Your objectives, plus what you already have: source code, compiled binaries, firmware images, documentation. Not a modeling project you have to staff.
- 2
Get a working emulation immediately
Stand up a Digital Twin Emulator fast, so you can start analyzing and understanding real behavior right away instead of waiting for a "finished" model.
- 3
Close the fidelity gap, measurably
The system automatically determines where emulation diverges from your system, corrects one discrepancy at a time, and checks each fix for side effects. The process repeats until your objectives are met.
- 4
Get an emulation you can trust
You end with a running system emulation and a fidelity report: precise, documented guarantees about performance and accuracy. Providing transparency and provenance to the modeling and validation stack, not a black box that technically passes.

Composability
One device.
Then a system.
Then the whole fleet.
Your product never ships alone
It runs inside larger systems, alongside hardware built by teams you'll never meet. Scalable Cyber composes individual emulations into connected environments where those systems communicate exactly as they would in the field which lets you test the interactions, not just the parts.
Emulate a product's subsystem
Take individual components of a system (drones, smartphones, aircrafts etc.) and compose them into a single unit. Place that unit into a shared environment with the other systems it has to work with. Then exercise the whole thing. And because every component is a hardware-accurate DTE thats been generated and measured, the system you're testing against is a reliable digital model of your product, ready for the field.
For teams operating critical systems
The same composition supports cross-system risk and exploit assessment across connected technologies without exposing physical infrastructure to potential damage and production downtime.
Who our tools are for
Built for the teams closest to the hardware.
Scalable's DTEs gives OEM engineering teams a way to build, debug, test and validate against physical device behavior from day one to create repeatable operational workflows that directly translate to field tests. Operators of critical systems and assurance partners use the same emulations to assess risk and resilience across the technologies they depend on.

Built by people who have spent their careers on this problem.
Our team has contributed to most of the significant emulation projects in the field: Unicorn Engine, QEMU, Styx Emulator, the Penguin Rehosting framework, and AVATAR2. The team also regularly contributes to research published at venues including USENIX, PLDI and NDSS. That work is the reason we solve the problem across several verticals at once, rather than one.

Every emulation ships with its accuracy documented.
Scalable Cyber produces a fidelity report with precise guarantees on performance and accuracy to support the transparency software assurance requirements customers need. Currently supporting select commercial partners and US government agencies on multiple awards and task orders.
