Trusted identity for every connected field device
Building trust at the network edge
Modern energy networks depend on millions of connected field devices collecting data, controlling equipment and supporting critical operations. Establishing trusted device identity at the edge strengthens cybersecurity, operational resilience and lifecycle integrity across both existing and new infrastructure.
Protecting the first point of trust
Field devices, including smart meters, sensors, gateways, controllers and automation equipment, form the operational foundation of modern energy networks. As these devices become increasingly connected, ensuring their identity, integrity and authenticity is essential for maintaining secure and resilient critical infrastructure.
Every connected device should be trusted
Modern utility networks rely on thousands, or even millions, of connected field devices. Before participating in the network, every device should be able to prove its identity and operate with trusted firmware throughout its operational lifetime.
Trusted device identity strengthens operational resilience while supporting secure authentication, firmware integrity and lifecycle management.
Built for existing infrastructure
Replacing field devices across large-scale utility networks is rarely practical. Security solutions therefore need to integrate with existing infrastructure while supporting modern cybersecurity requirements and long-term operational continuity.
A hardware-rooted approach enables operators to strengthen cybersecurity without costly infrastructure replacement or operational disruption.
Supporting compliance and lifecycle management
Field devices often remain operational for 15 to 30 years while regulatory requirements continue to evolve.
Establishing trusted device identity from the outset simplifies compliance with regulations such as CRA, NIS2 and IEC 62443 while supporting secure lifecycle management throughout the device’s operational life.
How CyberRock supports connected field devices:
Immutable hardware identity for every field device
Secure authentication and firmware integrity
Trusted sensor data and device communications
Secure lifecycle management and firmware updates
CRA, NIS2 and IEC 62443 readiness
Post-quantum resilience for long-lived infrastructure
Why utility operators choose SandGrain
Critical infrastructure depends on knowing that every connected field device is genuine, trusted and operating as intended. Hardware-rooted device identity strengthens cybersecurity while supporting regulatory compliance, operational resilience and the secure management of long-lived infrastructure.
Why cybersecurity matters in field devices
Energy and utility operators manage infrastructure that society depends on every day. As electricity grids, substations and utility networks become increasingly connected, cyberattacks can disrupt essential services, impact operational continuity and expose organisations to growing regulatory and operational risk.
