Nozomi Networks and DER Security Corp (DERSec) have integrated their technologies to address cyber-physical threats targeting distributed energy resources (DERs), including electric vehicle (EV) charging infrastructure, battery energy storage systems, and microgrid controllers.
As EV charging networks increasingly integrate with distributed generation and storage assets, infrastructure operators face growing exposure to attacks that manipulate control commands or falsify telemetry data. Traditional IT network monitoring tools often lack visibility into native power and DER protocols, limiting their ability to detect control-layer anomalies.
The joint solution combines Nozomi Networks’ OT and IoT visibility platform with DERSec’s physics-informed analytics engine. DERSec Sentry performs deep packet inspection across native DER protocols including SunSpec Modbus, DNP3, IEEE 2030.5, and OCPP, the protocol widely used in EV charging systems.
By validating physical process variables against expected electrical behavior, the system is designed to distinguish between operational faults and malicious command injection, firmware manipulation, or telemetry spoofing.
For EV infrastructure operators, this approach provides an additional layer of protection for charging stations integrated into microgrids, fleet depots, and distributed energy environments. As charging assets become bidirectional and more tightly coupled to grid services, maintaining command integrity and measurement accuracy becomes critical for both operational stability and grid resilience.
The integrated platform supports deployment across on-premise, wireless, and cloud-connected environments spanning IT, OT, and IoT networks. In addition to threat detection, use cases include asset inventory, troubleshooting, and operational monitoring in distributed energy environments.
The collaboration reflects a broader shift toward security architectures that incorporate electrical domain awareness alongside traditional network analytics, particularly in EV charging and distributed energy ecosystems.
