Role overview:

The SOC Analyst is responsible for monitoring, investigating, and responding to security alerts across the organisation’s technology estate. The role supports the day-to-day operation of the Security Operations Centre by triaging alerts, analysing security events, escalating confirmed risks, and helping to improve detection and response capability. The successful candidate will play an important role in protecting the organisation from cyber threats while supporting operational resilience, regulatory requirements, and PCI DSS compliance obligations.

The role requires hands-on experience with security monitoring tools, incident triage, log analysis, endpoint security, cloud security alerts, and structured incident response processes. Experience with Microsoft Sentinel, Microsoft Defender XDR, SentinelOne, vulnerability management processes, and working within regulated or payments environments would be advantageous.

• Triage and investigate alerts to determine severity, business impact, and appropriate response actions.
• Escalate confirmed or suspected incidents in line with SOC procedures and incident response playbooks.
• Analyse logs, endpoint telemetry, identity events, and cloud activity to identify suspicious behaviour and potential compromise.
• Support containment, evidence gathering, and remediation activities during security incidents.
• Contribute to the continuous improvement of detection logic, alert quality, and SOC operational processes.

Security Tooling & Operational Support

• Use Microsoft Sentinel, Microsoft Defender XDR, SentinelOne, vulnerability management platforms, and other security tools to support daily SOC operations.
• Assist with alert tuning by identifying false positives, recurring noise, and opportunities to improve detection accuracy.
• Maintain clear investigation notes, incident records, and operational documentation.
• Support vulnerability monitoring, validation, and escalation where findings present operational or compliance risk.

Governance, Compliance & Reporting

• Support SOC activities that help maintain compliance with PCI DSS and other regulatory requirements.
• Produce clear, accurate, and timely updates on incidents, investigations, and operational security issues.
• Maintain audit-ready records relating to alerts, investigations, incidents, and response actions.
• Support internal and external audit activities by providing evidence and operational context where required.

Key Deliverables

• Security alerts triaged, investigated, and escalated within agreed operational procedures.
• Incident records and investigation notes maintained to a consistent and audit-ready standard.
• Confirmed threats escalated promptly with clear evidence, impact assessment, and recommended next steps.
• False positives, recurring alert noise, and detection gaps identified and fed into continuous improvement activity.
• Security monitoring, vulnerability, and incident response activities supported in line with SOC priorities.
• Improved visibility, response consistency, and operational discipline across SOC activities.

Who you are

• Experience triaging and investigating security alerts in a SOC or security operations environment.
• Good understanding of common cyber threats, attack techniques, endpoint activity, identity events, and network indicators.
• Hands-on experience using SIEM, EDR, XDR, or similar security monitoring platforms.
• Ability to analyse logs, correlate events, and document findings clearly.
• Understanding of incident response processes, escalation routes, and evidence handling.
• Awareness of PCI DSS, regulatory expectations, or working in a controlled operational environment.

Nice-to-Have
