Services

Engineering help, with a concrete output.

Security architecture, hands-on implementation, and certification support for teams facing consequential technical decisions.

Start with a defined question

Four ways to begin.

Agree the scope and expected evidence first. Extend into implementation or ongoing advisory when the work calls for it.

A focused starting point

Security architecture review

Where are the most consequential design risks?

What you bring
Architecture diagrams, data flows, security requirements, and access to the engineers who own the system.
Scope
One agreed system or integration boundary. Implementation and penetration testing are scoped separately.
What you receive
Architecture findings, prioritized remediation, and an engineering debrief.
Timing
Agreed after reviewing system scope, access, and evidence availability.

A focused starting point

Cryptographic migration assessment

What has to change, and in what order?

What you bring
Library and protocol inventory, build dependencies, target platforms, and compatibility obligations.
Scope
Dependency and migration planning for an agreed product boundary. Migration implementation is a separate work package.
What you receive
Dependency inventory, compatibility risks, validation needs, and a sequenced migration roadmap.
Timing
Agreed after reviewing system scope, access, and evidence availability.

A focused starting point

Certification readiness review

What evidence or engineering gaps could delay evaluation?

What you bring
Target scheme and scope, design documentation, existing test evidence, and known evaluator questions.
Scope
Readiness assessment and engineering support. Formal evaluation and certification remain with the relevant laboratory and scheme.
What you receive
Evidence gaps, remediation priorities, and a practical evaluation-preparation plan.
Timing
Agreed after reviewing system scope, access, and evidence availability.

A focused starting point

AI integration threat model

What can the workflow access, disclose, or cause?

What you bring
Data sources, retrieval design, model and tool interfaces, identities, and proposed business actions.
Scope
One agreed AI workflow and its trust boundaries. Model benchmarking and adversarial testing can be scoped separately.
What you receive
Trust-boundary diagram, misuse scenarios, control recommendations, and verification priorities.
Timing
Agreed after reviewing system scope, access, and evidence availability.

How an engagement works

  1. Frame the problemIdentify the system, the decision, the constraints, and the people who need the answer.
  2. Inspect the realityConnect design documentation to code, configuration, dependencies, and observed behaviour.
  3. Leave usable evidenceDeliver prioritized findings, traceable decisions, and a clear next engineering step.

Start with the engineering problem

What needs to be secure?

Share your system, the decision ahead, and the constraints. We’ll work out a useful next step.
