Role purpose

The postholder provides advanced technical security analysis, leads complex investigations, improves the maturity of security controls and advises stakeholders on cyber risk. The role combines hands-on security operations with control ownership, specialist guidance, assurance and continual improvement.

Role scope and level

• Senior technical practitioner with authority to lead complex operational security work within agreed governance.
• Responsible for risk-based recommendations, improvement of procedures and subject-matter advice for incidents, vulnerabilities, identity controls, data protection and security tooling.
• Expected to coach colleagues, influence technical teams and translate threat, control and risk information into clear management updates.
• Focuses on control maturity, assurance quality, repeatable processes and measurable reduction of cyber security risk.

Key responsibilities

1. Security operations leadership

• Lead complex security investigations across endpoint, network, identity, email, cloud and application data sources.
• Define triage criteria, alert handling standards, escalation paths and quality checks for security operations.
• Review high-impact alerts and incidents, ensure proportional response and remove barriers to containment and remediation.
• Develop and improve detection logic, playbooks, dashboards and operational procedures.

2. Incident response leadership

• Coordinate response to significant cyber security incidents in line with the incident management process.
• Lead technical analysis for malware, phishing, credential compromise, insider risk, data exposure, privilege misuse and suspicious network activity.
• Ensure evidence handling, incident timelines, decisions, lessons learned and remediation actions are complete and auditable.
• Produce post-incident reviews and track corrective actions through to closure.

3. Risk, governance and assurance

• Translate technical findings into risk statements, control weaknesses and prioritised remediation plans.
• Support risk assessment, risk acceptance, audit and assurance activity with clear evidence and professional judgement.
• Advise on relevant information security legislation.
• Contribute to security standards, control testing, supplier assurance and management reporting.

4. Data Loss Prevention and Multi-Factor Authentication control ownership

• Own or act as technical lead for Data Loss Prevention (DLP) monitoring, rule tuning, alert quality, exception handling and escalation.
• Own or act as technical lead for Multi-Factor Authentication (MFA) control performance, exception governance, break-glass account checks, privileged access enforcement and conditional access design.
• Analyse Data Loss Prevention (DLP) and Multi-Factor Authentication (MFA) trends to identify control gaps, user behaviour issues, data handling risks and improvement opportunities.
• Ensure control documentation, operating procedures and evidence packs are complete, current and aligned to policy.

5. Vulnerability, threat and configuration management

• Lead vulnerability prioritisation using exploitability, asset criticality, exposure and business impact.
• Challenge and support remediation plans for high-risk vulnerabilities, insecure configurations and unsupported systems.
• Develop recurring reporting on vulnerability trends, control gaps and remediation performance.
• Use threat intelligence to improve detection, hardening and risk prioritisation.

6. Security architecture and technical assurance

• Review proposed changes, projects and new services for security risks and control requirements.
• Advise on secure design for identity, endpoint, network, cloud, logging, data protection and resilience controls.
• Validate that logging, monitoring, access control, encryption, backup and recovery requirements are included in project delivery.
• Recommend improvements to security tooling and integration, including automation where proportionate.

7. Metrics, reporting and continual improvement

• Produce clear management information on incidents, vulnerabilities, Data Loss Prevention (DLP), Multi-Factor Authentication (MFA), control exceptions, detection coverage and remediation performance.
• Define Key Performance Indicators (KPIs) and Key Risk Indicators (KRIs) for security operations and control assurance.
• Identify process inefficiencies, repeat incidents and control weaknesses, then lead improvement actions.
• Maintain a forward view of emerging threats, technology changes and relevant good practice.

8. Leadership, coaching and stakeholder management

• Coach colleagues on investigation quality, evidence standards, tooling, communication and risk-based decision-making.
• Provide clear guidance to infrastructure, application, cloud, data protection, service desk and business teams.
• Present security findings, risks and recommendations to technical and non-technical stakeholders.
• Promote a constructive security culture focused on proportionate risk management and business enablement.

Required knowledge, skills and experience
