Role Summary

The Security Incident & Vulnerability Management Consultant operates within the Operational Integrator (OI) function to support the transition to a multi-supplier (SIAM) model within a Defence environment.

The role focuses on understanding, aligning and governing existing high-severity security incident management (S3/S4) and vulnerability management processes across suppliers. Ensuring a consistent, risk-based approach in line with client policy and regulatory requirements, supported by appropriate evidence.

The outcome is a coherent, evidence-driven view of security risk, covering both active incidents and underlying vulnerabilities, with processes standardised and ready for BAU handover.

This is a governance and coordination role, not a hands-on SOC, incident response, or vulnerability remediation function.
