K524E Secure KVM Switch: 4-Port, DisplayPort Video, Dual-Display.

How to Order

The K524E is a secure 4-port Display-Port dual-head KVM Switch.

It allows users to share peripherals - keyboard, mouse and monitor - between four different security-level networks/computers.

The K524E DisplayPort Secure KVM is the industry’s first Secure KVM switch with DisplayPort. This product offers the highest possible separation between four connected computers and features patented AUX channel firewall designed to protect from DisplayPort internal security vulnerabilities. 

K524E supports four isolated computers each hav‌ing DisplayPort video output.
It is especially designed to provide the highest possible isolation between connected computers with each computer hav‌ing four video output ports. Each computer may connect to up to two independent displays and operate in a dual-display mode.

K524E is equipped with an RDC port enabling user-friendly, comfortable remote control of the KVM switch.

Security is further leveraged by the inclusion of a USB user authentication port (DPP) that enables connecting a Biometric or Smart Card Reader, requiring the insertion of a physical authentication card or identification of a fingerprint to access the various computers/networks.

The K524E meets the requirements of companies challenged by the need to provide both secret and top-secret network access together with unclassified or Internet access. It is a perfect fit for high-security organizations such as government agencies, military and financial institutions, and any other organization that handles sensitive and confidential information.
