CAMPBELL, Calif., Feb. 4, 2026 /PRNewswire/ -- JinkoSolar Holding Co., Ltd. (the "Company"), JinkoSolar, a global leader in clean energy technology, today announced that its Jinko ESS North American business unit has received IEC 62443-2-4 certification from exida, a globally recognized authority in industrial cybersecurity and functional safety.
IEC 62443-2-4 is an internationally respected standard that defines best practices for secure development lifecycle (SDL) processes for service providers of industrial automation and control systems. Certification confirms that cybersecurity is not treated as a bolt-on feature but is embedded across system design, development, integration, testing, deployment, and lifecycle management.
Unlike companies that retrofit cybersecurity in response to regulation or market pressure, Jinko ESS has championed a "secure by design" philosophy across its energy storage products, systems, and processes since the inception of its ESS business. Over time, Jinko ESS has doubled down on investment in cybersecurity governance, engineering, and controls, recognizing early that energy infrastructure demands the same rigor as critical industrial systems.
"Cybersecurity is not simply a department at Jinko ESS. It is a foundational design principle," said Jeff Juger, U.S. Managing Director of Jinko ESS. "From architecture decisions to supplier management to incident response planning, cybersecurity is ingrained into how we operate."
IEC 62443-2-4 certification validates that Jinko ESS operates a formal, audited secure development lifecycle; integrates threat modeling, risk assessment, and secure supply chain; maintains controlled vulnerability management and patching processes; and applies cybersecurity controls across 3Ps: people, process, and products. This independent assessment confirms that Jinko ESS's cybersecurity practices meet the rigorous standards of utilities, data centers, regulators, and sophisticated enterprise customers operating in high-risk environments.
"True security is found in the process, not just the product," added Michael Medoff, Director of Certification at exida. "By achieving IEC 62443-2-4 certification, Jinko ESS has proven they have the rigorous system Integration and Maintenance processes and governance required to protect critical infrastructure. This independent validation gives utilities and enterprise customers the confidence that security is ingrained in every step of their partner's service lifecycle."
