SMA, a Germany-based manufacturer of photovoltaic system technology, has implemented a structured cybersecurity framework for its energy products. SMA has developed all critical software in-house to reduce external code risks and ensure stronger system security. Cybersecurity has been integrated through a Secure Development Lifecycle that includes risk analysis, security testing, and threat monitoring from design to operation. A dedicated Security Operation Centre is responsible for continuous system monitoring and timely patch management for identified vulnerabilities. SMA has applied technical measures such as endpoint protection, encrypted communications, password policies, and regular penetration testing. Organizational controls include a Product Security Incident Response Team, a Technical Cybersecurity Manager, and partnerships with OWASP and the SunSpec Alliance. SMA is ISO/IEC 27001:2022 certified and has been working with independent security researchers through a responsible disclosure process to strengthen vulnerability detection and response.
