01 / The systemIn development
Security shouldn’t
stop at the surface.
A firewall separates networks. Its software still has to do exactly what it’s supposed to do.
We’re building the proof into the stack, from the kernel and drivers to the programs that move your data.

The rules that
move your data.
The programs define how the firewall handles data. Our approach starts with explicit requirements and checks the implementation against them.

Apalis iMX8QM.
A Toradex system on module built around NXP’s i.MX 8QuadMax processor. 82 × 45 mm of compute within the firewall’s modular architecture.
Software guarantees depend on the execution environment. The module’s behavior and interfaces are part of the assumptions that verification must make explicit.

A proof behind
the boundary.
Software assurance starts
with precise requirements.
Our vv workspace brings code, specifications, and proof work together. Engineers review what a component must guarantee, with AI assisting the verification process.
Put the code to proof.
A multi-agent pipeline supports the work of verifying the implementation against its specification.
Keep judgment human.
Review proposed statements and changes in context before accepting what the system must guarantee.

Across the boundary.
Without the guesswork.
For government teams and defense integrators, crossing a network boundary is a software assurance problem as much as a networking problem.
