Coordinate containment, eradication, recovery, root-cause analysis, and technical communication with customer incident response teams and internal stakeholders.
~ Perform proactive threat hunting across OT and converged OT/IT environments to identify abnormal asset behavior, unsafe protocol usage, lateral movement, persistence mechanisms, and industrial attack techniques.
Security Monitoring, Packet Analysis, and Forensics
Review OT alerts and correlate them with enterprise SIEM telemetry, asset context, and industrial communication patterns.
Perform advanced packet analysis using Wireshark, support forensic triage, validate malware indicators, and guide evidence collection for OT investigations.
~ Lead onsite and remote implementation activities, conduct customer workshops, deliver technical presentations, and provide expert troubleshooting during upgrades, migrations, and health checks.
Serve as the senior technical SME for OT SOC operations and provide strategic guidance during architecture reviews, escalations, and service improvement planning.
~ Create custom parsers, integrations, playbooks, SOPs, and knowledge artifacts that improve OT visibility, response consistency, and service quality.
Optimize detection logic, data onboarding, alert tuning, and reporting workflows to improve MTTR, response quality, and customer outcomes.
~ OT Domain, Protocol, and Asset Expertise
Apply deep working knowledge of OT/ICS components including ICS, SCADA, DCS, PLC, RTU, HMI, historians, engineering workstations, industrial Ethernet, and IIoT-connected assets.
Produce executive dashboards, weekly and monthly SOC reports, compliance reporting, threat intelligence summaries, deployment status updates, and detailed root-cause analyses.
Maintain high-quality technical documentation for deployments, incidents, integrations, customer environments, and engineering changes.
~ Compliance, Risk, and Assessments
Support OT cybersecurity assessments, vulnerability management activities, and control validation aligned to standards such as ISA/IEC 62443, NIST CSF, and customer-specific governance requirements.
Ensure delivery quality, SLA adherence, audit readiness, and operational alignment with plant safety and production constraints.
~ Mentor L1 and L2 analysts, guide implementation engineers, review technical deliverables, and conduct knowledge transfer sessions for customers and internal teams.
