Trusting the Grid Edge: Securing Connected Devices with UL 2941

Establishing operational resilience in energy systems

As energy systems become increasingly connected, the number of intelligent field devices, including protection relays, remote terminal units (RTUs), smart sensors and gateways, is rapidly expanding. While these devices offer more efficient operations, they can also introduce cybersecurity risks that can impact uptime, reliability and safety. In many cases, these edge devices (or end points) represent the initial point of compromise, where attackers can manipulate data and control signals, leading to operational disruption and risks to safety-critical processes. UL 2941, the Standard for Cybersecurity of Distributed Energy and Inverter-Based Resources, helps build trust.

This webinar explores why device-level security is foundational to operational resilience and how organizations can establish trust in their connected assets. We introduce UL 2941, a new cybersecurity standard for network-connected, software-operated devices, and its basic and advanced cybersecurity requirements. We explain how UL 2941 forms device-layer security as part of an integrated, multilayer system and organizational — rather than checklist-based — approach to cybersecurity. From both a regulatory compliance and operational resilience perspective, UL 2941 helps lay the foundation for protecting communications, systems and critical infrastructure operations.
