What is Operational technology (OT)?

Operational technology (OT) refers to the hardware and software systems that monitor, control, and automate physical processes and industrial operations. It enables organizations to manage critical infrastructure, manufacturing equipment, and industrial environments safely and efficiently.

Organizations in industries such as manufacturing, energy, transportation, and utilities rely on technology to control physical processes and equipment. These systems help operators manage everything from production lines and power grids to water treatment facilities and transportation networks.

How does Operational Technology work?

OT environments connect sensors, controllers, industrial devices, and management systems to automate and monitor physical operations. These components continuously collect data and execute commands to keep processes running efficiently.

A typical OT environment includes:

• Sensors that collect operational data.
• Controllers that process inputs and execute actions.
• Industrial devices that perform physical tasks.
• Monitoring systems that provide operational visibility.
• Operators who oversee and manage processes.

These components work together to ensure safe, reliable, and efficient operations.

Why is Operational Technology important?

Organizations depend on OT systems to maintain critical operations and deliver essential services. Any disruption can impact productivity, safety, and business continuity.

Key benefits include:

• Automated process control.
• Improved operational efficiency.
• Real-time monitoring.
• Enhanced safety management.
• Reduced manual intervention.
• Better resource utilization.

As industries become more connected, securing OT environments has become a major cybersecurity priority.

Common cybersecurity risks in OT environments

Modern OT systems increasingly connect with IT networks, cloud platforms, and remote management tools. While this connectivity improves efficiency, it also expands the attack surface.

Common OT security risks include:

• Ransomware attacks.
• Legacy system vulnerabilities.
• Unauthorized remote access.
• Insider threats.
• Supply chain attacks.
• Network misconfigurations.

Organizations should implement strong security controls to protect operational systems from disruption and compromise.

How Hexnode UEM supports organizations with connected OT environments

Many OT environments rely on supporting endpoints such as rugged tablets, handheld devices, operator workstations, digital signage systems, kiosks, and industrial Android devices. Securing and managing these devices plays an important role in maintaining operational reliability.

Hexnode UEM helps organizations manage the endpoints that interact with operational systems. IT and operations teams can use a centralized console to configure devices, deploy applications, and enforce security policies across distributed industrial environments.

Key capabilities include:

• Kiosk management: Lock devices to approved applications and workflows used in industrial operations.
• Remote device management: Troubleshoot and manage field devices without requiring on-site intervention.
• Application deployment: Distribute operational and business-critical applications across managed devices.
• Policy enforcement: Apply security settings consistently across devices used in OT environments.
• Asset visibility: Track device inventory and monitor the status of managed endpoints.

While Hexnode UEM does not manage industrial controllers such as PLCs or SCADA systems, it helps organizations secure and manage the endpoints that operators, technicians, and field personnel use to interact with OT infrastructure.
