Industrial OT Security by Palo Alto Networks is a Zero Trust-based security solution for protecting operational technology (OT) environments, assets, networks, and remote operations. It combines machine learning with passive identification technology and crowdsourced telemetry to profile and assess risks across industrial control systems. The solution provides security coverage for partially air-gapped to fully cloud-connected environments, offering protection for industrial infrastructure including Distributed Control Systems (DCS), Industrial Control Systems (ICS), Human-Machine Interfaces (HMI), Programmable Logic Controllers (PLC), Remote Terminal Units (RTU), SCADA systems, historians, and jump servers.
