Fortinet FortiGate 121G OT Security Service, 1-Year (FC-10-F121G-159-02-12)

Industrial networks increasingly sit behind a FortiGate, but standard NGFW rule sets don’t understand Modbus, DNP3, or IEC 60870-5-104. The FC-10-F121G-159-02-12 adds FortiGuard OT Security to the FortiGate 121G for a 1-year term, giving the firewall the signatures, dashboards, and vulnerability mappings it needs to treat OT traffic as a distinct zone — not just unclassified traffic flowing past standard IT policies.

What OT Security Covers

The FortiGuard OT Security service (-159-) extends the FortiGate 121G’s inspection capabilities to industrial protocols and OT-specific threat intelligence. Enabled features include: OT-aware IPS signatures covering protocols like Modbus, DNP3, IEC 60870-5-104, and BACnet; application detection for hundreds of OT/SCADA applications; OT vulnerability correlation that matches traffic patterns to known CVE entries for industrial systems; virtual patching to block exploitation attempts against unpatched OT assets; and OT compliance dashboards referenced to NERC CIP and IEC 62443 frameworks.

Who Buys This

IT/OT convergence projects where a FortiGate 121G is positioned as the boundary firewall between the corporate IT network and an operational technology segment. Manufacturing, energy, utilities, and building automation environments where PLCs, RTUs, or SCADA systems sit behind the firewall. Security teams needing compliance reporting for OT environments without deploying a separate OT-specific sensor platform.

Activation and Delivery

This is an electronic subscription licensed to the FortiGate 121G by serial number. After purchase from DataCenter360.ca, the license key arrives by email within 0-1 business days. Register it in the Fortinet Support Portal under the device serial number. The service activates on the next FortiGuard signature update. No hardware ships with this subscription.

OT Security as a Standalone Service

OT Security is not a line item in the standard ATP, UTP, or Enterprise bundles. It is an add-on purchased separately and applied to the FortiGate 121G regardless of what FortiGuard bundle is already active. This means you can layer OT coverage on a device running UTP or ATP without changing the base subscription tier.
