Nozomi Networks Inc., a recognized leader in OT, IoT, and CPS security, has partnered with DER Security Corp (DERSec) to strengthen cybersecurity protections for distributed energy resources (DERs). Through this strategic technology integration, the companies aim to address rising cyber-physical threats targeting battery energy storage systems, solar installations, electric vehicle (EV) chargers, and microgrid controllers.

As global power grids continue shifting toward renewable and distributed energy models, cyber risks have grown significantly. Consequently, distributed assets have emerged as attractive targets for advanced threat actors. Traditional network monitoring tools, however, often fail to detect stealthy attacks that manipulate control signals or falsify telemetry data. By combining Nozomi Networks’ deep operational visibility and threat detection capabilities with DERSec’s physics-informed analytics, the companies are delivering a more advanced, energy-aware security layer tailored for security operations center (SOC) teams.

“As power grids worldwide shift to renewable and distributed energy, distributed assets have become prime targets for sophisticated threat actors. Traditional network monitoring can’t detect stealthy attacks that manipulate control signals or measurement telemetry. By integrating Nozomi Networks’ visibility and detection technology with DERSec’s physics-informed analytics, we are providing SOC teams with an energy-aware security layer to protect critical infrastructure.” stated Thomas Tansy, CEO of DERSec.

Nozomi Networks has built a strong reputation across the OT, IoT, and CPS security landscape by delivering superior operational visibility and advanced threat detection across complex environments. Today, its solutions monitor more than 115 million devices across thousands of deployments spanning energy, manufacturing, mining, transportation, utilities, smart cities, building automation, and other critical infrastructure sectors. Furthermore, organizations can deploy Nozomi Networks solutions onsite, across wireless networks, or in the cloud. By leveraging artificial intelligence, the company automates asset inventory, visualization, and monitoring across IT, OT, and IoT networks. In addition to cybersecurity, customers also use its platform for troubleshooting, asset management, and predictive maintenance.

Meanwhile, DERSec brings specialized expertise in securing energy infrastructure. Its DERSec Sentry platform performs deep packet inspection across native DER protocols such as SunSpec Modbus, DNP3, IEEE 2030.5, and OCPP. As a result, it can detect malicious commands, falsified telemetry, insider threats, and unauthorized firmware modifications in real time. Moreover, DERSec leverages digital twins and power-aware intelligence to differentiate between physical faults and cyberattacks an essential capability for AI data centers, microgrids, EV fleets, and utility-scale DER environments. This approach significantly reduces incident response and recovery times.

“Protecting the world’s critical infrastructure is strengthened by deep integration with specialized domain expertise and enterprise-scale security platforms. DERSec’s ability to translate complex electrical behavior into actionable security metrics perfectly complements Nozomi Networks’ visibility and threat detection capabilities. This joint solution helps operators eliminate blind spots in decentralized energy environments and ensures customers can maximize operational resilience against evolving threats.” Matthew Cowell, Vice President of Strategic Alliances, Nozomi Networks.

Together, Nozomi Networks and DERSec are setting a new benchmark for protecting distributed energy ecosystems against increasingly sophisticated cyber-physical threats.
