The problem we are asked to solve
- Cybersecurity work exists as documentation rather than engineering decisions.
- Requirements are written late, so architecture cannot support them.
- Suppliers and internal teams interpret security scope differently.
- Audit and assessment findings arrive too close to production.
What changes as a result
- Cybersecurity goals traceable from threat analysis to implementation
- Requirements engineering teams can build and verify against
- Architecture decisions supported by documented security rationale
- Work products structured for internal and external assessment
Scope of work
What the engagement covers
Scope is agreed per programme. These are the activities we most often deliver for this service.
- Item definition support
- Threat analysis and risk assessment (TARA)
- Cybersecurity goals and claims
- Cybersecurity concepts
- System and component requirements
- Architecture and interface review
- Security control definition
- Verification planning
- Work-product review
- Supplier cybersecurity alignment
- Post-development support
Engagement methodology
How we work
A predictable sequence, adapted to your process and release gates rather than replacing them.
- 01
Establish context
Agree the item boundary, interfaces, stakeholders, and the release gates the work must serve.
- 02
Analyse and define goals
Run or review the risk analysis and derive cybersecurity goals that can be turned into requirements.
- 03
Specify and review
Write technical requirements, review the architecture against them, and record design decisions with rationale.
- 04
Plan verification
Define what evidence each requirement needs and who produces it, including supplier-side activities.
- 05
Support execution
Stay engaged through implementation and review cycles so decisions remain traceable as the design changes.
Deliverables
Every engagement ends with artefacts your organisation owns and can defend in review.
- TARA documentation
- Cybersecurity goals
- Cybersecurity concept
- Technical cybersecurity requirements
- Traceability framework
- Review findings
- Remediation roadmap
Relevant standards
We help organisations interpret and implement these requirements. We do not certify or approve organisations.
- ISO/SAE 21434
- UNECE R155
- ISO 26262
- AUTOSAR
Typical use cases
- New vehicle platform or domain controller programme
- Cybersecurity concept preparation ahead of type approval
- Supplier work-product review and gap closure
- Security requirements definition for an ECU family
Evidence
Case studies covering Cybersecurity Engineering work are being prepared for publication. Automotive security engagements are normally confidential, so we discuss comparable scope, method, and deliverables directly rather than publishing unverifiable claims.
