IoT & Hardware Threat Modeling

Find the design flaws that scanners and pen tests miss — before a board exists. I model how your product can be attacked and turn it into a prioritized set of design changes your team can act on.

Most security problems in connected products are not coding bugs — they are design decisions no one questioned. Threat modeling questions them on purpose, early, when a fix costs an afternoon instead of a recall.

1. Diagram the system. Map data flows and the trust boundaries where attacks concentrate.
2. Apply STRIDE to every element — the STRIDE method makes the gaps systematic.
3. Build attack trees for the highest-value targets, using attack trees for embedded hardware.
4. Rank and assign mitigations so every risk becomes an actionable ticket.

• Data-flow and trust-boundary diagrams
• STRIDE coverage across every interface
• Attack trees for your highest-value targets
• A short, ranked list of design changes — not a document no one reads
• An optional security requirements document your team can build from

The cheapest time to fix a flaw is before the first board spin, but a threat model also pays off for products already in the field and for regulated devices where safety is on the line — such as implantable medical devices.

• Using the OWASP IoT methodology in practice

Do you need hardware or firmware to start?
No. Threat modeling works from your architecture and data-flow descriptions — no device required.

How is this different from a penetration test?
Threat modeling finds design flaws before they ship; a penetration test validates what already shipped. They complement each other.

What do you need from me?
A description of the system, its interfaces, and what you are protecting.

Do you sign NDAs?
Yes, always — before we get into specifics.

Let’s map your product’s attack surface and turn it into a plan you can build from.
