Fortinet FortiGate-401E-DC OT Security Service, 1-Year (FC-10-D4H1E-159-02-12)

Industrial networks run protocols and devices that standard IT security was never designed to handle. The FortiGuard OT Security Service for the FortiGate-401E-DC (FC-10-D4H1E-159-02-12) adds a dedicated operational technology intelligence layer to this DC-powered appliance: device detection signatures, vulnerability correlation tuned to industrial hardware, IPS rules built for OT protocols, and virtual patching that blocks known exploits without interrupting live production systems.

What the OT Security Service Covers

The subscription activates four protection layers specific to OT environments on the FortiGate-401E-DC:

• OT Device Detection: A continuously updated signature package identifies and classifies OT endpoints on your network, including PLCs, HMIs, RTUs, and industrial sensors. FortiOS uses this inventory to drive NAC policy enforcement and network segmentation without needing a separate asset management tool.
• OT Vulnerability Correlation and Virtual Patching: Cross-references detected OT device inventory against known CVEs published for industrial hardware and applies FortiOS virtual patches so active exploits against unpatched devices are blocked at the firewall, not at the endpoint. This is particularly valuable for OT equipment that cannot accept downtime for patching.
• OT Application Control and IPS: Extends FortiOS Application Control and IPS with signatures specific to industrial protocols including Modbus, DNP3, IEC 61850, and others maintained by FortiGuard Labs. This allows the FortiGate-401E-DC to enforce granular access policies and detect anomalous OT protocol behavior.
• OT Dashboards and Compliance Reports: Provides visibility dashboards and compliance reporting templates aligned to OT security frameworks, giving operations and security teams a unified view of industrial asset risk from within FortiOS.

Who Needs This Service

This subscription fits any organization where the FortiGate-401E-DC sits at the boundary between corporate IT and operational technology. Utilities, manufacturers, oil and gas operators, water treatment facilities, and critical infrastructure teams running mixed IT/OT networks are the primary audience. The DC power supply on the 401E-DC is specifically designed for industrial environments where AC power is unavailable or unreliable, making it a natural fit for substations, control rooms, and remote OT sites. MSSPs managing industrial customers also benefit, as the service provides structured OT visibility within the existing FortiOS management workflow without deploying a separate OT-specific platform.

Activation and Electronic Delivery

This is a digital subscription. After purchase, Fortinet delivers license credentials electronically, typically within one business day. You register the key in the Fortinet Support Portal and activate it from the FortiGate-401E-DC’s FortiOS interface. No hardware shipment is involved, and the service activates as soon as the FortiGate connects to FortiGuard distribution servers. Licenses can be managed and renewed through Fortinet’s customer portal. This subscription is available to customers worldwide.

OT Security Versus a Full FortiGuard Bundle

The FortiGuard OT Security Service (FC-10-D4H1E-159-02-12) is an à-la-carte subscription covering the OT-specific detection and patching layer only. It is not included in any standard FortiGuard bundle. If the FortiGate-401E-DC is also handling enterprise internet traffic, pairing this with a UTP or Enterprise Protection bundle adds IPS, web filtering, DNS security, anti-malware, and FortiCare Premium support alongside OT coverage. Both subscriptions run concurrently on the same appliance, and OT Security is the recommended addition for any FortiGate deployed at the IT/OT boundary.
