Fortinet FortiGate 400F-DC OT Security Service, 3-Year (FC-10-FD4H0-159-02-36)

Securing an operational technology network goes beyond traditional IT firewall rules. The FortiGate 400F-DC is already deployed in many OT environments because of its DC power support and campus-scale throughput — but protecting PLCs, HMIs, SCADA servers, and industrial protocols requires OT-specific intelligence that only activates with the FortiGuard OT Security Service. This 3-year subscription (FC-10-FD4H0-159-02-36) keeps that intelligence continuously updated for three years without an annual renewal gap.

What OT Security Covers

The service delivers three distinct capabilities on the FortiGate 400F-DC:

• OT Device Detection: A continuously updated signature package that identifies and fingerprints OT hardware — PLCs, RTUs, engineering workstations, and field devices — giving your team a live inventory of everything on the OT segment.
• OT Vulnerability Correlation and Virtual Patching: Maps detected OT devices against known CVEs and applies virtual patches inline on the FortiGate to block exploit attempts against devices that cannot be taken offline for firmware updates. Activation is through NAC Policy and virtual patching profiles in FortiOS.
• OT Application Control and IPS: Expands the standard signature set with hundreds of industrial protocol signatures covering Modbus, DNP3, EtherNet/IP, IEC 60870-5-104, PROFINET, and more — policing industrial traffic at the application layer.

Who Needs This Service

This subscription is for organizations running OT infrastructure behind a FortiGate 400F-DC: manufacturers with production floor networks, utilities managing SCADA and DCS systems, oil and gas operators, water treatment facilities, and any enterprise that extends a FortiGate to the OT perimeter. The 400F-DC’s DC power input makes it particularly suited for environments like substations and industrial control rooms where power architecture matters.

It is also useful for IT/OT convergence teams consolidating visibility. OT device detection feeds into the Security Fabric, so OT assets appear in FortiAnalyzer and FortiManager alongside IT assets — no separate OT inventory tool required.

Activation and Delivery

This is an electronic license. After purchase, DataCenter360.ca delivers the contract details to your inbox within 0 to 1 business days. Activation is through the Fortinet Support Portal: log in, register the contract to your FortiGate 400F-DC serial number, and OT Security signatures push automatically via FortiGuard distribution. No hardware is shipped. The license is not region-locked — it activates on any FortiGate 400F-DC regardless of where the appliance is installed.

OT Security vs. the Standard Bundles

The FortiGuard Enterprise Protection, UTP, and ATP bundles do not include OT Security — it is only available à la carte. If the FortiGate 400F-DC already runs an Enterprise or UTP bundle, the OT Security Service stacks on top to add OT-specific coverage without replacing existing features. If the appliance is starting from scratch with only FortiCare, pairing OT Security with at least the UTP bundle ensures full IPS, AV, and web filtering alongside OT capabilities.
