Cyber Security Incident Response (CSIRT) Manager

Adeptis Group is recruiting on behalf of a leading Critical National Infrastructure organisation undergoing a major cybersecurity transformation. This is a high-impact role at the heart of a global enterprise that provides essential services to millions of people every year.

We're seeking a hands-on and strategic Cyber Incident Response Team (CIRT) Manager to design, implement, and mature a group-wide cyber incident response function. This is a rare greenfield opportunity to build and shape the incident response operating model from scratch—working alongside a newly onboarded MSSP while setting the foundations for a future internal capability.

The Role

Designing end-to-end incident response processes, roles, and escalation paths
Defining the tooling roadmap for incident response and forensic capabilities
Acting as the primary liaison with the MSSP to align SLAs, KPIs, and operational playbooks
Leading incident coordination across internal and external teams
Building relationships with stakeholders across business units to ensure risk-aligned response
Developing a strategic business case to scale and insource CIRT capabilities
Driving continuous improvement through post-incident reviews and threat landscape analysis
Ensuring compliance with regulatory requirements and frameworks (e.g. GDPR, NIST, PCI-DSS, MITRE ATT&CK)

Requirements

5–10 years of experience in Security Operations, CIRT, or senior SOC roles
Strong leadership capability or experience managing incident response teams
Deep technical knowledge of SIEM, SOAR, EDR, and forensic tooling
Strong grasp of threat detection methodologies and security frameworks
Proven ability to engage senior stakeholders and drive alignment across functions
Recognised certifications (e.g., CISSP, CISM) preferred
Background in regulated or CNI environments is advantageous
