Cyber Security Consultant at London/Preston/Birmingham – 2 days per week Onsite
Security Clearance: Active SC Clearance is a must have
Job Description:
The Cyber Security Process Alignment & 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, the consultant ensures 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.
Key Responsibilities
Supplier Onboarding & Process Integration
- Develop structured onboarding packs for new suppliers covering:
- Security processes (e.g. incident management, vulnerability management, assurance)
- Policies, standards, and governance expectations
- Reporting and escalation requirements
- Define and agree:
- Supplier roles and responsibilities
- Interaction models between Supplier, SI, OI and Client
- Act as the central integration point for onboarding suppliers into the SIAM security model
Process Alignment (SIAM / OI Model)
- Work with Security Assurance, Incident and Vulnerability leads to translate defined processes into supplier-consumable guidance
- Ensure suppliers adopt and align to existing processes, with minimal change
- Identify and manage gaps between:
- Supplier capabilities
- Client expectations
- Established SI/OI processes
