Active Tamper-Proof System IOGEAR secure KVM switch hardware security is comprised of tamper-evident seals, active chassis intrusion detection, and tamper-proof hardware. Compliance with NIAP Protection Profile v4.0 certifies that non-approved USB peripherals will be rejected and cannot be connected to the secure KVM switch, providing high-level security, protection and data safekeeping. With the combination of physical and software security, secure KVM switches offer secure air-gap network isolation to prevent internal and external access to individual system with authorization while consolidating multiple workstations with varying security classification levels. Compatible with IOGEAR Remote Port Selector Securely select and switch between systems with optional external remote port selector that provides full operator control for an optimized user experience. Data Channel Isolation and Unidirectional Data Flow IOGEAR Secure KVM switches control and isolate data flow between the console device and the connected computers preventing any data transfer between the connected computers. Data channel isolation prevents data leakage between connected computers via isolated channel per port and unidirectional data flow ensures unidirectional data flow between the console devices and the selected computer. The secure KVM switch supports analog audio via speakers only. Multiple Video Interface Support Connect multiple to multiple port configurations with IOGEAR Universal KVM cables* enabling IT administrators options for preventing compatibility issues with diverse secure computer ecosystem. The universal KVM cables connect multiple video sources to a IOGEAR KVM even if they are using different display standards. This flexibility enables IT managers to deploy the same KVM switch across their network without the need for unreliable active cables or costly external video convert
