Nautilus OT is a monitoring solution for operational technology networks used in transportation and logistics environments, including warehouse automation, fleet tracking, and port operations. The product uses network sensors to provide visibility into OT assets and activity in real time. It is designed to identify unknown or unauthorized devices connected to the network, detect suspicious activity, and surface vulnerabilities in automation, tracking and fleet systems without interrupting ongoing operations. Nautilus OT also generates reporting intended to support compliance demonstration, referencing regulations such as NIS2, and provides board-level reporting on identified risks and assets. The stated goal of the product is to reduce operational downtime caused by cyber incidents such as ransomware, unsecured remote access, or loss of visibility and control over logistics systems, by giving operators and managers information to address risks before they cause disruption.</description> <parameter name="summary">OT network monitoring and asset visibility for transportation and logistics environments
