Fortinet FortiGate 61F OT Security Service, 1-Year (FC-10-0061F-159-02-12)

Most firewalls were designed for IT traffic. The devices on an OT network, whether programmable logic controllers, HMIs, industrial sensors, or SCADA systems, speak different protocols and have different vulnerability profiles. Deploying a FortiGate 61F at the boundary between IT and OT infrastructure is a common architecture for smaller converged environments; the FortiGate 61F 1-Year FortiGuard OT Security Service (FC-10-0061F-159-02-12) is the subscription that makes the 61F OT-aware for twelve months. Subscription license only, no hardware, delivered electronically worldwide.

What this service activates

The OT Security Service adds a dedicated set of detection and protection capabilities to the FortiGate 61F:

• OT Device Detection: the FortiGate 61F automatically discovers and classifies OT and ICS devices on monitored network segments, building a device inventory that covers PLCs, HMIs, RTUs, engineering workstations, and ICS-specific protocols.
• OT Vulnerability Correlation: known CVEs affecting discovered OT devices are correlated in real time. The 61F maps published vulnerabilities to the specific devices it has detected, surfacing the highest-risk exposures without requiring manual cross-referencing.
• OT Virtual Patching: where OT devices cannot be patched on a normal IT cycle, the FortiGate 61F applies IPS signatures as compensating controls, blocking exploit traffic targeting known vulnerabilities inline while underlying firmware or software update timelines are managed separately.
• OT Application and IPS Signatures: deep protocol decoders for industrial communication standards including Modbus, DNP3, IEC 61850, EtherNet/IP, and others. Application control and IPS rules enforce communication boundaries between OT zones, flagging commands outside expected operational parameters.
• OT Dashboards and Compliance Reports: visibility into OT device inventory, detected anomalies, and policy enforcement, formatted for both operational review and compliance documentation.

Who needs this service

This subscription is relevant for any environment where IT and OT networks share the same FortiGate 61F firewall. Manufacturing cells, building management systems, water treatment monitoring, utilities, and similar deployments that converge industrial control traffic with standard IT infrastructure on a smaller-footprint firewall are the primary use cases. If the 61F is purely in an IT context with no OT-segment traffic, this service adds no value; the IPS and AMP subscriptions address that use case more directly.

OT Security Service vs. the standard bundle tiers

The FortiGuard OT Security Service is an add-on subscription available independently of the ATP, UTP, and Enterprise bundle tiers. It does not come bundled in any of the standard FortiGate 61F subscription packages; it is purchased separately alongside or in addition to whatever base subscription is already in place. Enterprise bundle subscribers can add it as a complementary service; the same is true for UTP or ATP subscribers who need OT protection on a specific appliance.

Activation and delivery

The license is issued electronically and registered to a specific FortiGate 61F serial number through the Fortinet Support Portal. OT signature databases and device classification updates push automatically for the full 12-month term. No hardware ships. A valid FortiGate 61F is required before the license can be applied; the subscription is model-specific and cannot be transferred to a different platform.
