Cyber Digital Twins (CDTs) is a core technology within Cybellum's Product Security Platform. CDTs are digital replicas of a product's software and firmware, created by extracting and analyzing binary files from any product or component. CDTs provide a structured data set for cybersecurity analysis, including Software Bill of Materials (SBOM), Hardware Bill of Materials (HW BOM), version history, software licenses, hardware architecture details, OS configurations, API calls, cryptographic characteristics, and more. The technology operates across the full product lifecycle — from development through post-production — continuously detecting new risks for each product version. Security risks are assessed in the context of the full product system, from individual components to entire product systems, including inter-system architectures and external connections. CDTs support identification of vulnerabilities, zero-day risks, and regulatory compliance gaps by running collected data through a product vulnerability database. Policy compliance can be validated against 50+ standards, regulations, and best practices, including OS hardening and exploit mitigation requirements. Key use cases include: - Product risk management - Product cyber compliance - Vulnerability management - Incident response (PSIRT) - Software licensing management - Asset and SBOM management The technology also surfaces supply chain risks by providing an independent view of supplier software components, identifying risky suppliers and assessing existing ones.
