Secure-by-Design process
JSP 440 / JSP 453 aligned Secure-by-Design processes embedded across your SDLC — from concept and threat modelling through to build, test and accreditation, keeping every change inside the Authority to Operate envelope.
Solutions
Secure-by-Design & Assurance
Drawing on our knowledge of Secure by Design security frameworks such as NIST 800 and ISO 27001, HMG Security Standards, NCSC Guidelines, MOD Security Policy and JSP 440, and JSP 604, we are perfectly placed to support your organisation.
Frameworks & standards
We speak the language of your regulator
Every artefact we produce — HLDs, threat models, risk treatment plans, ITHC scopes and CAF reports — is written to survive design authority boards, accreditor scrutiny and audit.
- NIST SP 800-53
- NIST SP 800-218 SSDF
- ISO 27001
- HMG Security Standards
- NCSC Guidelines
- MOD Security Policy
- JSP 440
- JSP 604
- JSP 453
- Cyber Essentials Plus
- GovS 007 / GovS 005
- NCSC CAF / GovAssure
What we deliver
Assurance you can evidence, not just claim
Self-assessment trackers
Control self-assessment trackers mapped to NIST 800, ISO 27001 and NCSC CAF, giving you a live, auditable view of control coverage, gaps and remediation status across the programme.
Risk treatment plans
Structured risk treatment plans with owners, deadlines and residual risk acceptance routed through your Design Authority and Accreditor — written to survive scrutiny at board, audit and regulatory review.
Authority to Operate evidence
Continuous Authority to Operate evidence packs: HLDs, threat models, SIRAs, ITHC scopes, RMADS excerpts and compliance mappings assembled and maintained so accreditation is never a last-minute scramble.
Outcomes
What changes when assurance is continuous
Secure-by-Design is not a one-off gate — it is the discipline that keeps your programme inside its Authority to Operate at every stage. The result is less rework, fewer surprises at audit, and a security posture you can prove on demand.
- Security embedded from concept through production — not bolted on at audit
- A live, auditable trail of control coverage mapped to your regulator's framework
- Risk accepted at the right level, by the right authority, on your timeline
- Continuous Authority to Operate evidence, ready for any assurance gate
- Designs that survive Design Authority, Accreditor and audit scrutiny
- Reduced rework, reduced delay, reduced risk to your programme milestones
