The Belkin Modular Series of secure KVMs deliver all NIAP Protection Profile 4.0 certification required criteria in a KVM that is slightly larger than a smart phone. With a supplied remote control, the KVM can be easily mounted on the back of the monitor or under a desk to create a uniquely clean and decluttered work environment while enhancing ergonomics and without compromising security requirements. The remote control is recognized as part of the secure KVM per NIAP PP4.0 and provides the positive feedback operators need as to what channel and what security enclave he/she is working on. Further, optical data diodes on all USB connections assure uni-directional data flow of HID filtered information with better than -60 dB of isolation between channels.
