Secure 4-port, 4K HDMI and/or DisplayPort* KVM switch 

with a dedicated CAC port, NIAP Common Criteria Protection Profile for Peripheral Sharing Device version 4.0 certified 

Why Secure KVM Switch?
Traditional non-secure KVM switches offer centralized control of multiple computers, but offer no absolute isolation between them. This exposes systems to the possibility of malicious damage and disruption, and acquisition of sensitive data from one computer to another.

Sekuryx's secure KVM switch is designed for use in secure defense and intelligence applications where sensitive data must be protected. The switch is NIAP PPs 4.0 certified and equipped with the highest security features that meet today's information assurance safe control standards. The switch prevents data leakage between computers that can run at different security levels, eliminating any potential cyber threat.

Each model is equipped with internal anti-tamper switches, which sense attempts to open the device enclosure. Once the system identifies such an attempt, all the front panel LEDs will flash rapidly and the unit will become useless by shutting off connection with all attached PCs and peripherals disabling any functionality. The unit's enclosure is also protected with a tamper-evident seal to provide a visual evidence if the unit has been opened.

Ultra-Secure KVM Switching
CK4-HP104C is a 4-port HDMI and/or DisplayPort* KVM switch with a dedicated CAC port and support for 4K (3840x2160 @ 60Hz) resolution video. CK4-HP104C allows users to control KVM (keyboard, video and mouse) operation on four computers with HDMI or DisplayPort video. It features mechanical, electrical and optical signal isolation to prevent hacking and data leakage in environments where security is paramount. The unit's controller has a special protection feature that prevents reprogramming or reading the firmware.

With CK4-HP104C, all data relays are controlled by inverted signals, shielding connections from outside intrusion by forcing them each to work one at a time. Each port uses its own isolated data channel and each unit features non-reprogrammable ROM to better protect the switch's functions. Better yet, CK4-HP104C offers the highest security when accessing classified and public networks over the Internet through these isolated connections. By isolating connections between networks, CK4-HP104C ensures no data is leaked between secure ports and the outside world.

CK4-HP104C has clearly marked front-panel buttons for controlling the devices, so securely switching between sources is always simple. For high-grade secure switching made easy, look no further than CK4-HP104C.

CAC Support
CK4-HP104C supports CAC devices such as smart-card and biometric readers, bolstering security when using the device. However, Sekuryx takes CAC security even further, allowing users to assign specific peripheral devices to CK4-HP104C's CAC port. Once a peripheral device has been registered by an authenticated admin, users can then switch the connection between that device and the PC's along with KVM switching.

Keyboard and Mouse Emulation
The secure KVM switch emulates (simulates) the presence of a keyboard and mouse for every attached computer through a USB cable. Both selected and non-selected computers maintain a constant connection with the unit's keyboard-mouse emulation controllers, allowing for ultra-fast switching and restricting discovery of newly connected peripherals during switching operations. Emulation of keyboard and mouse also prevents direct connection between the peripherals and the connected computers, shielding systems from potential vulnerabilities. Opto-isolators are used in the unit to keep USB data paths electrically isolated from each other, providing high isolation and preventing data leakage between ports.

Secure EDID Learn and Video Emulation
CK4-HP104C simulates a generic EDID as default, allowing it to operate most of the connected monitors. Both selected and non-selected computers maintain a constant connection with the unit's video and EDID emulation controllers, allowing for ultra-fast switching and restricting discovery of newly connected monitors during switching operations. Upon activating the KVM switch, the unit will quickly and automatically learn new EDID for specific monitors. The unit prevents unwanted and unsecure data from getting transmitted between the computers and the display.
