Active SC clearance

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.

Key Responsibilities:

  • Develop supplier onboarding packs covering security processes, policies, governance and reporting.
  • 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.
