Fortinet FortiGate 40F-3G4G OT Security Service, 3-Year (FC-10-F40FG-159-02-36)

Many industrial control deployments run on 3-year infrastructure review cycles — equipment gets assessed, firmware audits happen, and procurement planning for the next wave begins. A 3-year FortiGuard OT Security subscription on the FortiGate 40F-3G4G fits that cadence exactly. The FC-10-F40FG-159-02-36 delivers three years of continuous OT signature updates, OT device fingerprinting, vulnerability correlation, and ICS/SCADA protocol inspection without requiring annual renewal at remote or unmanned sites.

What the OT Security Service Enables

Once activated, FortiGuard OT Security extends the FortiGate 40F-3G4G’s visibility and enforcement into industrial environments:

• OT Device Detection — Passive and active discovery of OT assets using industrial protocols (Modbus, DNP3, BACnet, IEC 61850, EtherNet/IP), building an inventory of controllers and sensors on the network.
• OT Vulnerability Correlation & Virtual Patching — Maps detected OT devices to known CVEs and applies firewall-based blocking rules for exploits targeting those devices, even when firmware updates aren’t feasible on legacy equipment.
• OT Application Control & IPS Rules — OT-specific signatures for industrial protocols and control applications, detecting anomalous behavior in Modbus, DNP3, and other ICS/SCADA traffic.
• OT Compliance Dashboards & Reports — Pre-built reporting for common OT compliance frameworks, surfaced through FortiGate or FortiAnalyzer.

Why the 40F-3G4G for OT Edge Sites

Remote OT sites — substations, pump stations, production cells at the edge of a distribution network — frequently rely on cellular connectivity where fiber isn’t available. The FortiGate 40F-3G4G’s built-in LTE modem handles both primary and backup WAN in a compact appliance already suited to wall-mount or DIN-rail environments. Adding OT Security at the firewall means every protocol traversing that cellular or wired path is inspected by OT-aware signatures, without deploying a separate inspection device.

Activation & Delivery

This is an electronic subscription. DataCenter360.ca delivers the license key within 0–1 business days of order. Activate under System > FortiGuard in the FortiGate GUI. OT signatures and device fingerprints begin syncing immediately. No hardware modifications required — the subscription is applied to an existing 40F-3G4G unit.

OT Security and Multi-Service Licensing

FortiGuard OT Security is an à-la-carte service — it is not included in the ATP, UTP, or Enterprise FortiGuard bundles. If a site also needs URL/DNS filtering, IPS, or malware protection alongside OT Security, those services can be added as separate subscriptions or through a bundle. Adding FortiGuard IPS alongside OT Security is particularly common on production-edge deployments where both OT protocol awareness and broader network-layer threat blocking are required.
