VISS VISSBOX is a hardware security device that physically sits between a network connection and an endpoint device, providing isolation through hardware-level and physics-based mechanisms rather than software. Key characteristics: - Acts as a physical network separator/intermediary between the network and the host device - Uses unidirectional optical data flow (optical separation) to enforce one-way data transmission, preventing remote code execution and network-based attacks from reaching the host - The "Victim Module" component resets to a verified clean state on every power cycle, providing an immutable operating environment - Requires no software installation, drivers, or configuration on the host side — plug-and-play operation - Compatible with Windows, macOS, and Linux operating systems - Designed for use in IT, OT (operational technology), and defense environments - Targets industrial, governmental, and defense endpoint use cases - Compact and portable form factor suitable for field deployment Security approach: - Relies on physical and optical properties rather than software-based detection or signatures - Immune to zero-day exploits by design, as threats cannot traverse the unidirectional optical barrier - No software updates required on the device itself Certifications and recognition: - Designed to pursue ISO 15408 EAL5+ and NATO SECRET certifications (both pending) - Backed by NATO DIANA program - Incubated by CISPA Helmholtz Center for Information Security - Winner of German StartUp Cup 2025 - Named Cybersecurity Innovator of the Year 2025 by EU Business News
