Vertiv Cybex SC940 Secure 4-Port DVI-I KVM Switch

The Vertiv Cybex SC940 is a NIAP PP 3.0-certified secure 4-port DVI-I KVM switch engineered for classified and sensitive compartmented information (SCI) environments where strict data isolation between connected systems is mandatory. The unit enforces unidirectional data paths for keyboard and mouse signals using hardware-enforced data diodes, ensuring that no data can traverse from a lower-classification system to a higher-classification host. An isolated, non-addressable microcontroller manages port switching, eliminating any firmware-level attack surface accessible via the connected computers.

The SC940 supports DVI-I video on all four ports, delivering crisp digital and analog display output for high-resolution workstation use cases without compromising the air-gap security model. The switch incorporates USB keyboard and mouse emulation with a fully filtered HID interface that strips all non-HID-compliant USB device classes, preventing unauthorized peripherals from being enumerated on connected hosts. Anti-tamper mechanisms, including a tamper-evident chassis and active intrusion detection circuitry, alert administrators to any physical compromise of the enclosure.

Designed specifically for defense, intelligence community, and regulated enterprise deployments, the SC940 conforms to the requirements of the NIAP Protection Profile for Peripheral Sharing Switches (PSS) Version 3.0. It supports simultaneous operation across systems classified at different security levels — including cross-domain workstation scenarios — and is suitable for deployment on classified networks governed by DISA STIGs and NIST SP 800-53 control families. The unit operates as a standalone desktop appliance requiring no host-side software drivers, reducing the software attack surface to zero.

Ideal for

• Cross-domain workstation consolidation in intelligence community SCIFs requiring simultaneous access to systems operating at multiple classification levels from a single keyboard, monitor, and mouse set
• Defense contractor engineering environments where engineers require isolated access to both classified development systems and unclassified administrative workstations without physical KVM swapping
• Federal civilian agency secure operations centers (SOCs) needing NIAP-certified peripheral isolation between analyst workstations connected to sensitive government networks
• Military command-and-control facilities deploying DISA STIG-compliant desktop infrastructure with hardware-enforced separation between mission and administrative IT systems
• Financial services firms and critical infrastructure operators subject to CIP or financial regulatory mandates requiring verified hardware isolation between trading systems and corporate IT endpoints
• Secure government data center console access where operators manage multiple servers across different network security zones from a single physically secured console station
