Cybellum is a product security platform provider founded in 2016, focused on helping manufacturers of connected and embedded devices manage cybersecurity across the entire product lifecycle. The company targets industries including automotive, medical devices, industrial systems, aerospace, and telecommunications. The core offering is a product security platform that enables manufacturers to manage and execute their product security and compliance processes. The platform addresses gaps that traditional IT, cloud, and OT security tools do not cover — specifically the security of embedded software within physical products. Key capabilities include software bill of materials (SBOM) visibility, vulnerability management, risk management across products and business units, and compliance with regulatory frameworks such as UNECE WP.29 R155 and R156 for automotive cybersecurity. Cybellum emphasizes automation of security analysis to handle the scale of modern device software, continuous lifecycle security from design through post-market, and integration with existing product development ecosystems including PLM, QMS, and CI/CD toolchains. The platform is designed to replace largely manual security processes that relied on generic IT security tools. The company works with customers such as Hyundai Motor Company and ASUS, and publishes annual industry research including the State of Automotive Cybersecurity report. Cybellum also offers consulting and professional services alongside its technology platform. Notable board members include representatives from LG Electronics, which has a strategic involvement with the company.
