Fortinet FortiGate 50G-DSL OT Security Service, 3-Year (FC-10-F50GD-159-02-36)

Industrial environments that route OT traffic through a FortiGate 50G-DSL face a specific challenge: the firewall handles IP-layer threats well, but OT protocol exploits and unmanaged ICS device vulnerabilities are a different category. The FC-10-F50GD-159-02-36 is a 3-year FortiGuard OT Security Service subscription that closes that gap, adding industrial visibility and threat coverage tuned for operational technology networks.

What the OT Security Service Provides

Three discrete capabilities are enabled by this license:

• OT Device Detection: the FortiGate monitors traffic and identifies connected operational technology assets, including PLCs, RTUs, ICS controllers, and field devices. Each detected device is profiled with protocol and vendor metadata, building an asset inventory without needing a separate OT management platform.
• OT Vulnerability Correlation and Virtual Patching: identified assets are compared against the FortiGuard OT vulnerability database. For any device with a known vulnerability, a virtual patch is deployed at the firewall level to block exploit attempts, without interrupting device operation or requiring a maintenance window.
• OT Application Control and IPS: industrial protocol signatures are added to the device’s IPS and Application Control engines, covering Modbus, DNP3, IEC 104, Profinet, EtherNet/IP, and related protocols.

Who Needs This

The FG-50G-DSL suits remote or branch sites that depend on DSL connectivity, including substations, water treatment facilities, and manufacturing branch offices with field equipment. A 3-year term is a common fit for organizations working within triennial security budget cycles or aligning subscription expiry with hardware refresh timelines.

Activation and Delivery

After checkout, DataCenter360.ca delivers the license key electronically within 0 to 1 business days. Activation takes place in FortiOS under System > FortiGuard using the provided key. No hardware installation is required. Service begins on the activation date.

Standalone OT Security vs. the FortiGuard Bundles

OT Security is available as a standalone service or as part of the Enterprise bundle (FC-10-F50GD-809-02-36). Ordering this license individually makes sense when the site already runs a UTP or ATP subscription and needs to add OT coverage as an incremental layer. The comparison below shows how the service maps to each bundle tier:

If the requirement includes IPS, web filtering, and OT Security together, the Enterprise bundle consolidates all of those into a single SKU at the same 3-year term.
