Electric grid operators face growing cybersecurity risks as IT and OT environments converge. Attackers who breach perimeter defenses often move laterally through internal networks, targeting high-value operational systems like SCADA and ICS. East-west traffic visibility — monitoring internal communications between systems inside the Electronic Security Perimeter — is critical for detecting this lateral movement early. Industrial protocols such as DNP3, IEC 61850, OPC, and Modbus require OT-aware monitoring tools, as traditional IT security solutions lack the context to interpret these communications. Regulatory standards like NERC-CIP-15 are reinforcing requirements for internal network monitoring within Bulk Electric System environments. Trend Micro's TrendAI Vision One platform is presented as a solution offering OT-aware detection, AI-driven anomaly analysis, asset discovery, and cross-environment correlation across IT and OT networks.
