We are looking for an experienced Cyber Security Consultant to join a major Defence programme, supporting the onboarding of new service providers into a complex SIAM / multi-supplier environment.

This is a security governance, supplier integration and operational readiness role, rather than a hands-on technical security position.

• Align incoming suppliers with established Incident Management, Vulnerability Management and Security Assurance processes.




• Define supplier roles, responsibilities and interaction models across the SIAM/OI environment.




• Identify and manage gaps between supplier capabilities and existing security requirements.




• Support Security Management Plans, compliance reporting, audit and assurance activities.




• Support Operational Readiness Reviews (ORR) and Service Commencement activities.




• Produce clear, reusable security and service management documentation.




• Coordinate with incoming and incumbent suppliers, transition teams and client stakeholders.




• Support operational readiness across incident management, vulnerability management, monitoring, backup/recovery, access control and service reporting.

Key Experience

• Cyber Security Governance, GRC or Security Assurance experience.




• Strong experience within SIAM / multi-supplier environments.




• Good understanding of security and service management processes.




• Experience with supplier onboarding, transition or transformation programmes.




• Strong stakeholder management and documentation skills.




• Experience supporting compliance, audit and assurance activities.




• Knowledge of NIST CSF, Secure by Design and NCSC guidance would be advantageous.

Defence or wider Government/high-security experience is highly desirable.If you have the required active SC clearance, are a sole UK national, and have strong security governance/SIAM experience, I'd be keen to hear from you.
