Viss Germany Endpoint Hardware Cybersecurity

VISS UG is a German deep-tech cybersecurity startup that specializes in hardware-enforced endpoint protection. Its core product, the VISSBOX , is a patented hardware appliance designed to physically decouple a computer from the Internet, preventing any digital pathway for malware to reach the device [1] [2] . By enforcing a unidirectional optical data flow (“light in, no code out” physics-based security), VISS aims to make remote cyber intrusions technically impossible at the endpoint [1] [2] . Founded by Maximilian von Lonski (CEO) and CTO Matthias Wild, VISS is headquartered in Kehl am Rhein, Baden-Württemberg [3] [4] .

The company emerged from the Karlsruhe Institute of Technology (KIT) startup ecosystem and has been supported by German innovation programs. VISS won third place in the 2024 SpeedUpSecure cybersecurity accelerator and the 2025 German Startup Cup in the cybersecurity category [5] [6] . Its technology targets applications in government, industrial, and defense environments, promising a new security layer aligned with European digital resilience goals. VISS is a private German startup (UG) focused on pioneering hardware-based cybersecurity for PCs.

The firm’s VISSBOX technology uses a patented optical decoupling method to create an irreversible one-way data channel, effectively air-gapping endpoints against remote threats [1] [2] . This novel approach aligns with EU/NATO priorities in cyber resilience and secure communications. VISS contributes to European strategic autonomy by creating an indigenous alternative to foreign security solutions in the cyber domain. It is embedded in European research networks (incubated in KIT/CISPA programs) and participates in transatlantic innovation channels (selected for NATO’s DIANA accelerator) [7] [5] .

So far, its funding and development have been backed by German and European science agencies (e.g. KIT’s StartUpSecure program), and it aims to integrate with NATO-compatible defense networks. However, the technology is pre-commercial (pre-TRL6) with no disclosed production funding or EU Defense Fund projects.
