Belkin F1DN102KVM-UN Secure KVM

The Belkin F1DN102KVM-UN is a NIAP-certified secure single-head DisplayPort KVM switch supporting 2 computers, CAC smartcard authentication, and full air-gapped data isolation between connected systems.

This switch exists specifically for classified or regulated environments where data leakage between connected computers is a hard security requirement, not a convenience feature. NIAP Protection Profile certification means it's been independently evaluated against government security standards, and CAC smartcard pass-through support lets government and defense users authenticate without a separate reader. Versus the Belkin Advanced Secure KVM, that's Belkin's broader secure KVM line, worth it comparing generations for buyers needing the newest NIAP PP4.0 certification specifically. Versus the Tripp Lite B002-DP1A4-N4, that supports 4 computers instead of 2, worth it for buyers needing more secure connections at a higher price.
