System security engineering

System security engineering for embedded and AI systems. It starts in the room with your developers, engineers and product managers, and ends with a working proof-of-concept your teams can carry into production.

Typical engagement
Scoped
Delivered by
Our operators, never subcontracted

  1. 01

    Sit with the team

    We work alongside your developers, engineers and PMs — and your users where it applies — until we understand the operational requirements of the system, the product or the enterprise network, and what it has to certify against.

  2. 02

    Ingest

    Findings from an Io test or a Europa operation feed straight in. Where a report already exists, the engineering starts from it instead of re-running the assessment.

  3. 03

    Prove it

    The control gets built and demonstrated against your real constraints — the hardware it runs on, the latency it has to hold, the team that has to maintain it.

  4. 04

    Hand off

    Each proof-of-concept ships with a complete breakdown of the implementation pathway: dependencies, sequencing, and the tradeoffs we hit so yours are not a surprise.

Operational requirements first

We work with the people who own the system

Security engineering that arrives as a document from outside the team gets implemented as far as it is convenient and no further. So we work inside the team instead — with the developers who will maintain the control, the engineers who know what the hardware will tolerate, the product managers who own the deadline, and, where it applies, the people who actually use the thing.

What comes out of that is a shared understanding of the operational requirements: what the system has to do, what it runs on, what it cannot afford to lose, and where the room to change it actually is. Every recommendation after that is built against those constraints rather than around them.

The standards you answer to

Engineering that has to certify, not just work

Systems that touch regulated data inherit its rules: cardholder data under PCI-DSS, protected health information under HIPAA, and personally identifiable information under whichever regime covers the people it describes. Those are engineering requirements, and we treat them as such — what the system may see, what it may retain, what leaves the boundary, and what has to be provable afterwards.

Hardware programs carry a second set. Automotive work answers to ISO/SAE 21434, and to UN R155 where type approval is in play. Drone and air programs have their equivalents — the DO-326A and ED-202A airworthiness security process specifications, plus whatever the certifying authority adds on top.

Establishing which of these applies before the architecture is fixed is the difference between a control that certifies and a retrofit that holds up a launch.

Proof, then pathway

A working control and the route to production

The deliverable is a proof-of-concept that runs, not a diagram of one. It is built against your constraints and demonstrated to the teams who will own it.

With it comes the implementation pathway, broken down completely: what has to change, in what order, what it depends on, what it will cost in performance or effort, and where we expect friction. Your development and engineering teams should be able to pick it up and ship it without a follow-on contract to interpret it.

The other way in is a finished assessment. Outputs from Io and Europa are designed to ingest directly here, so a report does not stop at the finding — it continues into the engineering that closes it.

Why we do it this way

Security outcomes that let you serve your clients better

The point of the work is not the control diagram. It is that your product keeps doing the thing your customers depend on it for, under conditions you have already tested. Security that stops delivery is a failure with better paperwork.

We build toward outcomes you can spend: approvals that move faster, fewer emergencies pulling your engineers off the roadmap, and evidence you can put in front of a client who asks how their data is handled. Our job is to leave you more able to serve the people you serve — not more compliant on paper.

What lands

Every engagement closes with the same artifacts, in your hands and in writing.

  • Operational requirements brief

    What we learned working alongside your team, and the standards the system answers to — written down and agreed before anything is engineered.

  • Working proof-of-concept

    The control built and demonstrated against your constraints, on the hardware or in the environment it has to live in.

  • Implementation pathway

    A complete breakdown for handoff: dependencies, sequencing, tradeoffs and the friction to expect.

  • Handoff to your engineers

    A working session with the teams who will own it, so the pathway leaves with the people who have to walk it.

Tell us what you are shipping. We will tell you how it breaks.

Scope calls are 30 minutes with the operator who would run the test, not a salesperson.
