The SDHN-4S-P is a 4-port, single-head DisplayPort to HDMI KVM switch with a dedicated CAC port and support for 4K (3840×2160 @ 30Hz) resolution video.  

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. IPGard’s Secure KVM Switch is designed for use in secure defense and intelligence applications where sensitive data must be protected. The Switch is NIAP PP 3.0 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, and eliminate any potential cyber threat.  

ULTRA-SECURE KVM SWITCHING

The SDHN-4S-P allows users to control KVM (Keyboard, Video and Mouse) operation on up to four computers with HDMI monitors. It features mechanical, electrical and optical signal isolation to prevent hacking and data leakage in environments where security is paramount. With the SDHN-4S-P, 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, the SDHN-4S-P offers the highest security when accessing classified and public networks over the internet through these isolated connections. By isolating connections between networks, the SDHN-4S-P ensures no data is leaked between secure ports and the outside world. The SDHN-4S-P has clearly marked front-panel buttons for controlling the device, so securely switching between sources is always simple. For high-grade secure switching made easy, look no further than the SDHN-4S-P.  

CAC SUPPORT

Many secure KVM switches support CAC devices, such as smart-card and biometric readers, bolstering security when using the device. However, IPGard takes CAC security even further, allowing users to assign specific peripheral devices to the SDHN-4S-P’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 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.  

SECURE EDID LEARN AND VIDEO EMULATION

The SDHN-4S-P 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 emulation controllers, allowing for ultra-fast switching and restricting discovery of newly connected monitors during switching operations. Upon activating the KVM, the unit will quickly and automatically learn new EDID for specific monitors. The unit then prevents unwanted and unsecure data from getting transmitted through DDC lines by means of secure EDID learning and emulation.
