Fortinet FortiGate 400F-DC OT Security Service, 5-Year (FC-10-FD4H0-159-02-60)

Running a FortiGate firewall in an industrial or OT-adjacent environment introduces a device category that standard IT security tools weren’t designed to see. PLCs, SCADA controllers, HMIs, and similar operational technology assets use proprietary protocols and are rarely patchable on the same schedule as IT endpoints. This 5-year FortiGuard OT Security Service subscription (FC-10-FD4H0-159-02-60) activates dedicated OT detection, vulnerability correlation, and virtual patching capabilities on the FortiGate 400F-DC for the full term without annual renewal interruptions.

What the OT Security Service Covers

Three capabilities are bundled in this subscription and activated on the FortiGate 400F-DC once the license is registered:

• OT Device Detection: A continuously updated signature package that identifies OT and ICS devices on the network and surfaces device metadata within FortiOS. The firewall can distinguish between a PLC, an HMI, and a generic endpoint, giving operators real visibility into what is connected on the industrial side.
• OT Vulnerability Correlation and Virtual Patching: The service matches detected OT devices against known CVEs and applies virtual patches directly on the FortiGate 400F-DC. Exploit traffic is blocked at the network layer without requiring firmware changes on the OT device itself. Configured through NAC Policy and the Virtual Patching profile in FortiOS 7.6.
• OT Application Control and IPS: Adds industrial protocol signatures (Modbus, DNP3, EtherNet/IP, IEC 60870-5-104, BACnet, and others) to the firewall’s Application Control and IPS engines. The FortiGate 400F-DC can enforce policy on operational traffic and block known industrial-protocol exploits in real time.

Who Needs This Subscription

The OT Security Service is appropriate for any organization that has deployed a FortiGate 400F-DC at the IT/OT boundary or inside a segmented operational network. Utilities, manufacturers, oil and gas operators, water treatment facilities, and critical infrastructure operators frequently use it to extend firewall threat coverage beyond standard IT traffic to the industrial assets driving physical processes.

It is also relevant for compliance programs such as IEC 62443, NERC CIP, or industry-specific security frameworks where documented OT device visibility and vulnerability management are formal requirements.

Activation and Delivery

This is an electronic subscription. After purchase, DataCenter360.ca delivers the license key by email within 0 to 1 business days. Registration is completed in the FortiCare portal at support.fortinet.com, where the key is tied to the serial number of the target FortiGate 400F-DC. Once registered, FortiGuard begins pushing OT Security updates to the device immediately. The 5-year term starts on the registration date.

OT Security as a Standalone Add-On

The FortiGuard OT Security Service is exclusively an à-la-carte subscription. It is not included in the ATP, UTP, or Enterprise Protection bundles. Those bundles address IT-focused threat categories (IPS, antimalware, URL/DNS filtering, DLP, and similar). If the FortiGate 400F-DC already runs an Enterprise bundle, adding the OT Security Service extends coverage to OT device detection and industrial-protocol enforcement, filling the gap the standard bundle does not address.

For organizations starting from scratch, FortiCare Premium support on the device is a prerequisite for firmware access and TAC support. The OT Security Service then layers OT capabilities on top, and a FortiGuard bundle or individual services covers the IT-side traffic.

Buying from DataCenter360.ca

DataCenter360.ca is an authorized Fortinet Select Partner. FC-10-FD4H0-159-02-60 ships as an electronic license key with no physical component, so geography is no barrier to ordering. Committing to a 5-year term avoids three separate annual renewal cycles and locks in current pricing for the duration. Volume pricing and co-term alignment on an existing FortiCare contract are both available by request through the quote form on this page.
