MON5 Fortezza is an operational technology network monitoring solution designed to detect anomalous activities in industrial environments. The platform monitors OT networks through peripheral probes installed at the machine level to provide comprehensive surveillance of industrial infrastructure. The solution analyzes network traffic in real-time using continuously updated rules to identify anomalies and suspicious behavior. It performs targeted queries on on-board devices to detect and report potential threats, including insider threats. The system is designed to maintain operational continuity while threats are present, minimizing downtime in industrial processes. MON5 Fortezza offers modular scalability, allowing organizations to start with the MON5 Tower solution and expand to the full Fortezza platform as infrastructure needs grow. The platform adapts to different sizes and complexity levels of industrial environments. The solution focuses on protecting critical infrastructure by providing in-depth monitoring capabilities specifically tailored for operational technology environments. It enables proactive security management through continuous monitoring and threat detection at the device level.
