Cyber Security Supplier and Process Consultant

The Cyber Security Process Alignment and Supplier Onboarding Consultant operates within the Operational Integrator (OI) function to support the onboarding of new service providers into a multi-supplier (SIAM) environment within a Defence programme.

The role focuses on translating established security processes, policies, and governance into structured onboarding materials, ensuring that incoming suppliers clearly understand their obligations and are aligned from day one.

Working closely with Security Assurance, Incident, and Vulnerability Management leads, you will ensure that supplier processes are understood, integrated, and evidenced, rather than redesigned. The outcome is a consistent, controlled onboarding approach that enables suppliers to operate effectively within the existing security operating model.

This is a governance, integration, and enablement role, not a hands-on operational security or engineering function.
