Reporting to the Threat Detection & Response Lead, the Security Analyst: 3rd Line is a senior technical role within the Security Operations Centre and provides the primary escalation path for complex incidents and investigations raised by 1st and 2nd Line analysts.

• Drive continuous improvement in detection capabilities by enhancing analytics, automation, threat intelligence and investigation processes.
• Assess customer security posture, uncover vulnerabilities and provide practical recommendations to reduce risk across cloud, identity, endpoint and network environments.
• Mentor and support SOC analysts, sharing knowledge, developing best practices and helping raise the overall capability of the team.
• Build trusted relationships with customers, clearly communicating security risks, remediation plans and technical insights while contributing to the ongoing evolution of the SOC service.
