Jinko ESS has received IEC 62443-2-4 certification, validating its secure development lifecycle and cybersecurity governance across ESS design, integration, and deployment
This standard differs from conventional IT-focused cybersecurity frameworks by addressing operational technology environments, making it particularly relevant for grid-connected and industrial energy infrastructure
It also strengthens system reliability, supply chain security, and regulatory readiness for utilities, data centers, and enterprise-scale energy storage deployments
Jinko ESS, the energy storage solutions (ESS) business unit of JinkoSolar, has received IEC 62443-2-4 cybersecurity certification for its North American operations. The certification was awarded by exida, an independent organization specializing in industrial cybersecurity and functional safety assessments.
The IEC 62443-2-4 standard defines cybersecurity requirements for industrial automation and control systems. Specifically, it focuses on the secure development lifecycle (SDL) of service providers, ensuring that cybersecurity is systematically embedded across system design, engineering, deployment, and operation management. Unlike traditional cybersecurity standards that mainly address IT systems or product-level protections, this standard emphasizes organizational processes, governance, and lifecycle management.
According to the Jinko ESS, this makes the standard particularly relevant for ESS, power electronics, grid-connected infrastructure, and critical energy assets, where system availability, reliability, and safety are equally important as data protection. These cybersecurity requirements are embedded from the early design phase rather than added later, reducing system vulnerabilities and lifecycle costs. In addition, it improves protection against cyber incidents by formal threat modeling and vulnerability management processes. It also boosts the confidence of utilities, data centers, and enterprise customers in cybersecurity controls that are independently audited and continuously maintained.
According to Jeff Juger, U.S. Managing Director of Jinko ESS, cybersecurity is treated as a fundamental design principle rather than a compliance task, stating that it is “embedded into architecture decisions, supplier management, and operational planning.”
From a certification perspective, exida highlighted that the assessment confirms the presence of formal system integration, maintenance processes, and governance structures. Michael Medoff, Director of Certification at exida, noted that the certification provides customers with confidence that cybersecurity controls are applied consistently across the service lifecycle.
