About This ShortList

In today’s industrial landscape, the convergence of information technology (IT) and operational technology (OT) systems introduces unique security challenges. OT environments are critical to infrastructure and require specialized security measures to protect against sophisticated cyberthreats. Unlike traditional IT security, OT security must address the complex interactions between digital systems and physical operations, ensuring the safety and reliability of industrial processes.

OT security solutions provide real-time monitoring and threat detection tailored to industrial protocols and systems. These solutions offer agentless deployments, supporting both wired and wireless networks and ensuring minimal disruption of critical operations. With comprehensive visibility into the network, OT security tools enable organizations to detect, investigate, and respond to threats promptly.

The OT security market is rapidly expanding as industries recognize the importance of safeguarding their critical infrastructure. This growth highlights the urgent need for specialized security solutions that can manage the unique requirements of operational environments, ensuring the safety, reliability, and continuity of essential services.

Threshold Criteria

Constellation considers the following criteria for these solutions:

  • Breadth of device coverage. Provides comprehensive visibility into a wide range of OT devices, including programmable logic controllers (PLCs), distributed control systems (DCSs), human/machine interfaces (HMIs), and industrial-Internet-of-Things (IIoT) devices 
  • Network traffic monitoring. Monitors network traffic for anomalies and suspicious activity specific to OT environments 
  • Integration with physical security systems. Integrates with physical security systems to provide a holistic view of the OT environment and enable coordinated response efforts 
  • OT-specific threat detection. Leverages threat intelligence and advanced analytics to detect known and emerging OT threats, including malware specifically designed to target industrial control systems 
  • Anomaly detection. Identifies deviations from normal operational behavior that might indicate potential threats, even in environments with limited security data from legacy systems 
  • Vulnerability management. Identifies vulnerabilities in OT devices and systems, allowing for timely patching and remediation 
  • Agentless deployments. Enables monitoring and security without requiring software agents on each device, critical in diverse OT environments
