Bring order to shared console access with a secure KVM designed for environments where every login matters. The ATEN CS1184H4C supports four computers through USB HDMI single-display switching, giving operators a straightforward way to move between systems without compromising access discipline. CAC support adds smart-card authentication for workflows that require identity verification at the console. PP4.0 security architecture is intended for controlled environments where the switching layer must stay predictable and tightly governed. That makes this model a strong fit for security operations, command desks, and regulated infrastructure teams that need more than a basic peripheral switch. The single-display design keeps the operator experience focused and efficient, especially where one primary monitor is the standard. With four ports, it provides the right density for smaller secure workstations, isolated admin desks, and tactical control points. For teams that want secure access without unnecessary complexity, this KVM delivers a disciplined, purpose-built approach.
