• Tune Dragos detections to improve fidelity, reduce false positives, and ensure critical findings and OT Watch alerts are appropriately routed to enterprise security teams.
• Support SIEM integration, detection forwarding, escalation workflows, and operational handoffs while providing OT-specific context for security investigations.
• Deploy and validate Dragos sensors for new or acquired sites and manage secure decommissioning when facilities are closed or divested.
