Fortinet FortiGate 81E-POE OT Security Service, 1-Year (FC-10-0081E-159-02-12)

Industrial control systems, SCADA platforms, and operational technology (OT) devices operate on protocols that standard IT security tools often ignore. The FortiGate 81E-POE 1-Year FortiGuard OT Security Service (FC-10-0081E-159-02-12) extends your FortiGate’s threat prevention to include OT-specific traffic: it identifies controllers, PLCs, and HMIs on the network, maps them against known vulnerabilities, applies virtual patches when real firmware updates are impractical, and uses IPS signatures written specifically for industrial protocols.

Note: The FortiGate 81E-POE is an E-series model. Organizations deploying FortiGate as an OT network segmentation point may want to evaluate a current-generation model for longer hardware support horizons.

What the OT Security Service Provides

• OT Device Detection: Identifies OT and ICS devices on the network by passively analysing traffic on Modbus, DNP3, EtherNet/IP, and other industrial protocols, building an inventory without requiring downtime or agent installation.
• OT Vulnerability Correlation: Detected devices are matched against Fortinet’s OT vulnerability database, flagging firmware versions with known CVEs so you know which controllers are exposed.
• OT Virtual Patching: When patching an OT device requires a planned maintenance window (or a vendor-approved firmware version that does not yet exist), IPS rules on the FortiGate block exploit traffic targeting the known vulnerability. This is standard practice in OT environments where uptime constraints delay patch cycles.
• OT IPS Signatures: Application control and IPS rule sets specific to industrial protocols (SCADA, DCS, building management) protect against exploitation of OT-specific vulnerabilities.
• OT Dashboards and Compliance Reports: Visibility into OT device inventory and risk posture is presented in dashboards aligned with common OT security frameworks.

Who Deploys This Service

This subscription suits any organization running OT or ICS equipment behind a FortiGate 81E-POE, including light manufacturing, utilities, facilities management with BACnet/Modbus devices, or multi-site operators that use FortiGate firewalls as the IT/OT network boundary. It is also used by IT teams taking on OT security responsibility for the first time, giving them device visibility before they develop a full OT security program.

Activation and Delivery

Electronic key delivery within one business day. After registration and activation, OT detection profiles become available in your FortiGate policy configuration. No sensors or additional hardware are required — the FortiGate 81E-POE’s inline inspection engine handles OT protocol analysis.

This Service Is à La Carte

The FortiGuard OT Security Service is not included in the ATP, UTP, or Enterprise FortiGuard bundles. It is purchased exclusively as a standalone subscription. If you need OT protection alongside standard FortiGuard services (IPS, AMP, URL filtering), you will need to licence those separately, or consider whether a higher-throughput current-generation platform with the Enterprise bundle may offer a simpler licensing model.

Buying from DataCenter360.ca

DataCenter360.ca supplies Fortinet FortiGuard licences as an authorized Fortinet Select Partner, with electronic delivery worldwide. The OT Security Service is a specialized subscription that not every Fortinet reseller is familiar with. If you have questions about which FortiOS version on the 81E-POE is needed to activate OT dashboards, or how virtual patching rules interact with your OT traffic policies, reach out before ordering.
