Serve as escalation support for security related investigations, providing expert-level analysis and guidance during active incidents
Execute root cause analysis and produce clear incident reports outlining timeline, impact, evidence, and remediation recommendations
Conduct proactive threat hunting across the identity, endpoint, network telemetry to uncover adversary behavior and reduce dwell time
Create and tune threat detections using SIEM (Security Information and Event Management) to improve alert fidelity and reduce false positives
Drive continuous improvement of network visibility and telemetry collection to strengthen detection and response capabilities
Perform regular security control assessments validating configuration effectiveness and closing gaps discovered during incidents or hunts.
