The lack of comprehensive visibility in OT networks is a critical cyber risk for industrial organizations. Legacy systems, proprietary protocols and IT-OT convergence have expanded the attack surface while leaving asset inventories incomplete and real-time monitoring limited.

In this insightful discussion, Steven Sim, Manjunath Pasupuleti, Shilpy Banerjee and Abdul Aziz Patail discuss:

• Why passive scanning, governance frameworks and granular asset registers - from Level 0 upward - are foundational to OT visibility;
• How organizations can implement tiered monitoring strategies, including dual-firewall architectures and SOC correlation, without disrupting live industrial operations;
• Which security investments - network segmentation, lateral movement controls and cyber hygiene - deliver the highest return for protecting ICS against modern threats.
