# genua Dioden (Data Diodes) genua Dioden (Data Diodes) is an OT Network Segmentation product by genua GmbH. It runs on-premises. Pricing is commercial (contact sales). Hardware data diodes enforcing unidirectional data transfer for sensitive networks. Checked October 2026. ## What is genua Dioden (Data Diodes)? genua Dioden is a product line of hardware data diodes designed to enforce unidirectional data transfer at sensitive network boundaries. The product family consists of two variants: - **cyber-diode**: Targeted at industrial monitoring use cases, enabling secure data transfer from networked production systems (e.g., industrial control systems) to a control center. - **vs-diode**: Designed for one-way data transfers into classified (SECRET-level) networks, meeting high-assurance government and defense requirements. Data diodes differ fundamentally from firewalls in that they permit only one-directional data flow by physical/hardware design — there is no configurable bidirectional path. This "Security by Design" approach ensures that data exfiltration from classified or sensitive networks, and unauthorized access to connected industrial systems, is prevented at the hardware level. The diodes are positioned for use in sensitive infrastructure environments including critical infrastructure (KRITIS), defense, public sector, and industrial/manufacturing sectors. Status messaging is used to maintain reliable and fast data transfer without requiring a return channel. The product line is typically deployed alongside complementary security solutions such as firewalls (genugate, genuscreen, genuwall) for environments where both unidirectional and controlled bidirectional communication is required.
