• Implement and tune EDR/XDR, SIEM, detections, and SOAR playbooks; run threat hunting and purple-team exercises.
• Lead incident triage, containment, and recovery, and keep clients updated with clear, timely communication.
• Own internal IT: onboarding/offboarding, SSO/MFA, access reviews, device management, and SaaS administration.
