VISS is a cybersecurity hardware company that develops a physical endpoint protection device called VISSBOX. The product is designed to sit between a network and an endpoint device, acting as a hardware-level security barrier using optical data separation — a unidirectional data flow mechanism based on physical principles rather than software code. Key product characteristics: - Hardware-based security that operates at the physical layer using optical separation - Plug-and-play design requiring no software installation, drivers, or configuration on the host device - Compatible with Windows, macOS, and Linux operating systems - Supports IT, OT, and legacy systems across industrial, governmental, and defense environments - Features an immutable OS that resets to a clean state on every power cycle - Designed to be portable and rugged for deployment in field and high-security environments VISS targets industrial, governmental, and defense sectors, including use cases such as traveling personnel, research laboratories, and battlefield command centers. The company is pursuing ISO 15408 EAL5+ and NATO SECRET certifications (pending). VISS has received recognition from several programs, including the German Ministry for Economy & Energy's Gründerpreis for Digital Innovations (2024), EU Business News Cybersecurity Innovator of the Year (2025), and the German StartUp Cup (2025). The company is part of the NATO DIANA program and is incubated by the CISPA Helmholtz Center for Information Security, indicating a German base of operations.
