Fortinet FortiAnalyzer BigData 4500G (20 TB/Day) OT Security, 1-Year (FC-10-FB45G-159-02-12)

Running the FortiAnalyzer-BigData-4500G at 20 TB/Day gives large OT operators the ingestion capacity to collect telemetry from thousands of field devices — but raw ingestion alone does not surface industrial risk. Renewing this OT Security Service keeps the analytics layer active that converts that data into actionable intelligence specific to operational technology environments.

Overview

The OT Security Service renewal activates four capabilities on the FortiAnalyzer-BigData-4500G that have no equivalent in the base platform license: advanced OT analytics that map log events to industrial asset profiles; OT risk and compliance reports aligned to frameworks including IEC 62443 and NERC CIP; event handlers that fire on OT protocol anomalies such as unexpected Modbus function codes or DNP3 session drops; and use-case correlation rules calibrated for Purdue Model network architectures. Where standard IT detection rules look for credential abuse and lateral movement, these correlation rules detect abnormal PLC communication patterns, unauthorized engineering-station access attempts, and firmware modification events — threats that generic SIEM logic routinely misses in OT traffic.

Who it suits

Utilities, manufacturing plants, oil and gas facilities, and water treatment operators that have deployed the FortiAnalyzer-BigData-4500G for centralized log analytics need compliance reporting that addresses IEC 62443 zone-and-conduit requirements and NERC CIP controls specifically, not IT-centric frameworks. MSSPs offering managed SOC services to industrial clients benefit from the pre-built event handlers and correlation rules, which cut the time required to build OT-specific detection logic from weeks to days. Any team responsible for incident response in mixed IT/OT environments will find the OT-aligned risk reports more defensible in regulatory audits than generic log summaries.
