Trusted battery systems built for decades of secure operation.
Building trust into every battery system
Battery Energy Storage Systems (BESS) are becoming a critical component of modern energy infrastructure. They support renewable energy integration, grid stability and energy trading, making them an increasingly attractive target for cyberattacks.
At the same time, operators must comply with evolving regulations such as the EU Battery Regulation and Digital Product Passport requirements while managing assets that remain operational for decades.
A hardware-rooted identity provides every battery module and Battery Management System (BMS) with trusted authentication and lifecycle integrity from manufacturing through to recycling.
Designed for long-life energy storage systems
Battery Energy Storage Systems (BESS) are becoming a critical part of modern energy infrastructure. They enable renewable energy integration, stabilise electricity grids and support the transition towards a more resilient energy ecosystem.
Operating for 15 to 30 years, these systems require security that remains effective throughout their entire lifecycle, from manufacturing and deployment to maintenance and end-of-life.
Every battery system needs a trusted identity
Every battery module and Battery Management System (BMS) should be uniquely identifiable throughout its operational lifetime. Trusted device identity enables secure authentication, firmware integrity and confidence that every component is genuine and operating as intended.
As battery systems become increasingly connected, establishing trust at the hardware level provides a strong foundation for long-term cybersecurity and operational resilience.
Preparing for Digital Product Passports
From February 2027, industrial and EV batteries placed on the European market must comply with Digital Product Passport requirements.
Trusted device identity and secure data provenance help manufacturers and operators demonstrate authenticity, traceability and regulatory compliance throughout the battery lifecycle, from production and operation to reuse and recycling.
Modernise existing battery infrastructure
Replacing operational battery systems is rarely practical. Security solutions therefore need to strengthen existing infrastructure without disrupting operations or introducing unnecessary complexity.
A hardware-rooted approach enables organisations to enhance cybersecurity, support long-term lifecycle management and prepare existing installations for future regulatory requirements.
