Secure, resilient energy networks
built on trusted device identity.
Building trust across modern utility networks
Energy utilities are rapidly evolving through smart grids, distributed energy resources and increasing digitalisation. Protecting these long-lived networks requires security that remains effective throughout the device lifecycle of every connected asset.
A hardware-rooted identity establishes trust starting at the device, enabling resilient operations, secure authentication and simplified compliance across both existing and new infrastructure.
Operating critical infrastructure at scale
Modern utility networks consist of thousands, or even millions, of connected devices distributed across large geographical areas. Protecting every endpoint while maintaining reliable operations has become one of the biggest cybersecurity challenges facing energy operators.
Trusted device identity provides a foundation for secure authentication, lifecycle integrity and resilient operations across both new and existing infrastructure.
Designed for modern utility networks
Energy infrastructure continues to evolve through smart grids, distributed energy resources and digital transformation. Security must evolve alongside it without adding unnecessary operational complexity.
Long-lived infrastructure requires a trusted foundation that remains effective throughout the device lifecycle of every connected asset.
Trust every connected asset
A modern utility network depends on thousands, or even millions, of connected devices. From substations and controllers to smart meters and gateways, every asset should be able to prove its identity before participating in the network.
Trusted device identity strengthens operational resilience while supporting secure authentication, firmware integrity and lifecycle management.
Securing legacy infrastructure
Replacing operational infrastructure is rarely practical. Security solutions must integrate with existing environments while supporting modern cybersecurity and regulatory requirements.
A hardware-rooted identity enables operators to modernise legacy infrastructure without costly rip-and-replace programmes or operational disruption.

Why energy & utility operators choose SandGrain
CyberRock helps operators strengthen cybersecurity across distributed energy networks by establishing trusted device identity, simplifying regulatory compliance and supporting resilient long-term operation across both new and existing infrastructure.
Why cybersecurity matters in energy & utilities
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.
