List of the Top Operational Technology (OT) Security Software for FortiGate NGFW in 2026

Ongoing asset identification, vulnerability assessment, threat monitoring, and continuous discovery are essential for your Internet of Things (IoT) and operational technology (OT) devices. To foster innovation within IoT and OT, it is crucial to implement robust security measures across all devices in these categories. Microsoft Defender for IoT offers a solution that operates at the network level without requiring agents, allowing organizations to deploy it swiftly. This tool is compatible with a wide range of industrial machinery and can seamlessly integrate with Microsoft Sentinel and other security operations center (SOC) tools. It supports deployment in both on-premises settings and Azure-connected environments. The lightweight nature of Microsoft Defender for IoT enables it to provide device-layer security, which is particularly beneficial for new IoT and OT projects. Utilizing passive, agentless network monitoring, this solution generates a thorough inventory and detailed analysis of all IoT and OT assets without disrupting network operations. Furthermore, it can analyze various industrial protocols to extract crucial device information, such as the manufacturer, device type, firmware version, and IP or MAC address, thereby enhancing overall security visibility and management. This comprehensive approach not only safeguards devices but also strengthens organizational resilience against potential threats.

Access Gate functions as a comprehensive network security solution intended for on-premises deployment in industrial and vital environments. It can be utilized as a hardware appliance or via virtualization, and it creates managed security zones within the pre-existing network structure. This platform proficiently detects and inventories connected operational technology (OT), information technology (IT), and Internet of Things (IoT) devices while applying identity-based access controls and executing microsegmentation strategies. Moreover, it supports secure remote access to designated machines, thereby boosting operational efficiency. By employing proxy-based connections, organizations can protect legacy systems, and features such as session recording and tamper-proof event logs support compliance and operational evaluations. This solution empowers enterprises to effectively separate production networks from enterprise systems, limit lateral movement throughout the network, and provide temporary access to vendors and integrators when necessary. Specifically designed for security, IT, and operations teams across sectors like manufacturing and utilities, Access Gate is essential for preserving the integrity of critical infrastructure environments. Its advanced capabilities effectively respond to the increasing demand for heightened security in the face of a more interconnected operational landscape, and as industries evolve, the need for such robust solutions will only intensify.

The integration of IT, cloud, and industrial control networks (ICS) has heightened the vulnerability of your industrial operations to cyber threats. To address this challenge, Cisco Cyber Vision has been specifically created to foster teamwork between OT and IT departments, ensuring the safety and continuity of production. Embracing Industrial Internet of Things technologies can help you capitalize on the advantages of digital transformation in the industry. It is essential to kick off your OT security initiative by compiling a precise inventory of your industrial assets, communication flows, and network architectures. Enhancing your Security Operations Center (SOC) with OT context will enable you to utilize the investments made in IT cybersecurity to safeguard your OT infrastructure. You can elevate your OT security strategy by providing comprehensive compliance information that encourages collaboration between IT and OT specialists, ultimately strengthening the overall security framework. This integration between teams not only improves security but also enhances operational efficiency across your organization.
