Cyber Security Manager

We're looking for a Cyber Security Manager to act as the trusted operational partner for enterprise customers using managed cyber security services. You'll own service governance, customer success, continual improvement and major incident coordination, helping customers strengthen their security posture while ensuring exceptional service delivery. This is a highly visible role that combines cyber security expertise, customer engagement and service leadership across SOC, SIEM, MDR, threat intelligence and incident response services.

What You'll Be Doing

• Act as the primary customer contact for managed cyber security services.
• Lead service reviews, governance meetings and operational forums with technical and executive stakeholders.
• Ensure services are delivered in line with contractual commitments, SLAs and customer expectations.
• Translate complex security data into meaningful business insights, recommendations and executive reports.
• Drive Customer Success Plans and Continuous Service Improvement initiatives.
• Monitor service performance across SOC, SIEM, MDR, EDR/XDR, vulnerability management and threat intelligence services.
• Coordinate the response to major security incidents, managing communications, escalations and stakeholder engagement.
• Identify security risks, trends and opportunities to improve customer security maturity.
• Partner with technical, commercial and solution teams to enhance service quality and customer outcomes.
• Support service growth and retention by identifying opportunities to deliver additional value.

What We're Looking For

Essential

• 5+ years' experience in a Security Manager, Service Delivery Manager, Cyber Operations Manager, SOC Manager or similar customer-facing cyber security role.
• Strong understanding of managed cyber security services, including SOC, SIEM, MDR, EDR/XDR, threat intelligence, vulnerability management and incident response.
• Experience managing enterprise or multinational customer relationships within a cyber security or managed services environment.
• Proven ability to lead customer service reviews, governance meetings and executive stakeholder discussions.
• Experience managing escalations, major incidents and post-incident improvement activities.
• Strong analytical skills with the ability to interpret security data and produce actionable recommendations.
• Experience producing executive reports, security performance updates, risk summaries and service improvement plans.
• Knowledge of cyber security frameworks and standards such as ISO 27001, NIST, PCI-DSS and GDPR.

Desirable

• Experience working within a Managed Security Service Provider (MSSP) environment.
• CISSP, CISM, CCSP, CRISC or equivalent cyber security certifications.
• ISO 27001 Lead Implementer, Lead Auditor or ISO 27005 certifications.
• ITIL certification.
• GIAC, CREST or vendor-specific certifications within SIEM, EDR/XDR or cloud security technologies.
• Experience supporting service growth, commercial discussions and customer success programmes.

Why This Opportunity Stands Out

• Work directly with senior customer stakeholders including CISOs, CTOs and Security Leaders.
• Influence cyber security strategy, service maturity and long-term customer outcomes.
• Exposure to a broad portfolio of security services including SOC, SIEM, MDR, EDR/XDR, Vulnerability Management and Threat Intelligence.
• Play a key role in major incident coordination and cyber resilience improvement.
• Drive meaningful service transformation and continuous improvement initiatives.
• Operate at the intersection of cyber security, customer success and service leadership.
