Fortinet FortiGate 401F-DC OT Security Service, 1-Year (FC-10-FD4H1-159-02-12)

A plant firewall that cannot see Modbus or DNP3 is guessing at half its traffic. The FortiGuard OT Security Service (FC-10-FD4H1-159-02-12) gives the FortiGate 401F-DC a one-year subscription to industrial protocol signatures and an OT threat feed, turning opaque control-network flows into something the appliance can actually inspect and enforce.

What the OT Security Service covers

This subscription turns the 401F-DC into an OT-aware firewall for the one year it runs:

• OT application control and IPS signatures for industrial protocols such as Modbus, DNP3 and IEC 61850.
• A continuously updated OT threat feed tuned for supervisory control and data acquisition traffic.
• Virtual patching for legacy programmable logic controllers and human-machine interfaces that cannot be patched in place.
• Visibility into industrial assets and protocols crossing the IT and OT boundary.

Who needs it

Plants, utilities, water and energy operators and other industrial sites run this on the 401F-DC where the appliance guards the line between the corporate network and the control environment. It is the service to add when a general-purpose firewall must also understand SCADA and industrial protocols rather than treat them as opaque traffic.

One service versus the Enterprise bundle

OT Security ships inside the Fortinet Enterprise Protection bundle. Buying this standalone line makes sense when the 401F-DC already carries a UTP subscription or a separate FortiGuard stack and OT visibility is the missing piece. If you are starting fresh and also need intrusion prevention, antivirus and web filtering, the Enterprise bundle usually delivers better value than assembling single services. The 401F-DC page lists both paths.

Activation and delivery

The service arrives as an electronic FortiCare token. Register it against the 401F-DC serial in the FortiCloud and FortiCare portal and the appliance begins pulling OT signatures and threat intelligence, with automatic updates across the one year term. No box is shipped, so DataCenter360.ca fulfills the order worldwide.
