What is OT Network Monitoring?<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

OT Network Monitoring is the process of continuously observing and analyzing traffic, devices, communications, and activities within an Operational Technology (OT) environment. It helps organizations detect threats, maintain visibility across industrial control systems (ICS), reduce OT risks, and improve the security and reliability of critical operations.<\/span>\u00a0<\/span><\/p>

As industrial environments become increasingly connected, OT network monitoring has become a foundational part of industrial cybersecurity. From manufacturing plants and energy grids to transportation systems and water facilities, organizations rely on OT security monitoring to identify abnormal behavior, unauthorized access, and potential OT attacks before they disrupt operations.<\/span><\/p>

OT network monitoring refers to the practice of monitoring operational technology networks to gain visibility into OT systems, industrial devices, protocols, and communications. Unlike traditional IT security, which focuses on data confidentiality and user endpoints, OT security prioritizes system availability, uptime, and operational safety.<\/span>\u00a0<\/span><\/p>

An OT network typically includes industrial control systems (ICS), programmable logic controllers (PLCs), supervisory control and data acquisition (SCADA) systems, sensors, and other connected industrial assets. OT network monitoring platforms inspect OT network traffic in real time to\u00a0identify\u00a0anomalies, detect vulnerabilities, and\u00a0monitor\u00a0device behavior without interrupting operations.<\/span>\u00a0<\/span><\/p>

Modern OT network monitoring solutions<\/a> often use passive monitoring techniques to avoid disrupting sensitive industrial environments. These platforms provide organizations with better industrial network visibility, OT asset discovery, and OT threat detection capabilities.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t
