Security by Design

Security built into the architecture, not patched at the end.

What we do

We work alongside your product and engineering teams to build security in from the design: threat modeling, architecture decisions, secure patterns and acceptance criteria, so entire classes of flaws never come to exist.

We bring the mindset of people who break systems to the design table: we anticipate abuse before the first line is written.

How we do it

01

Architecture discovery

We map components, data flows and trust boundaries.

02

Threat modeling

We identify plausible abuse and its by-design countermeasures.

03

Patterns & guardrails

We define reusable secure patterns and acceptance criteria.

04

Ongoing enablement

We review key decisions as the product evolves.
