Map Yokogawa SOC handoffs by site, owner, SLA, and plant state

Yokogawa presents a managed IT/OT security operations center with continuous monitoring, incident tickets, workflows, and service levels. Buyers need a site-specific handoff matrix showing who owns triage, when the plant team takes control, how operating state changes escalation, and which evidence closes the service-customer loop.

A Nozomi Networks anomaly is not an incident declaration

Nozomi Networks presents asset visibility, anomaly detection, and threat analysis for OT and IoT environments. An anomaly can focus investigation, but accountable operations and security leaders still have to decide whether observed behavior is expected change, degraded operation, policy breach, or a declared incident.

NIST CSF 2.0 organizes outcomes—not OT control instructions

NIST Cybersecurity Framework 2.0 provides a taxonomy of cybersecurity outcomes across six functions, including the added Govern function. The framework can structure an OT program and its evidence, but it does not prescribe a safe control design, determine site-specific risk, or prove that an industrial system is secure or compliant.

NIS2 incident reporting starts with entity scope—not a universal timer

Directive (EU) 2022/2555 establishes staged reporting duties for significant incidents, but the operating clock depends on entity scope, national transposition, competent authority, awareness, significance, and the facts of the incident.
