Secure, 8-port, 4K**, DVI-I dual-display KVM switch 

compliant with PSD PP v4.0 (protection profile for peripheral sharing switch, version 4.0) security requirements 

• Always-on chassis intrusion detection – renders the ATEN PSS PP v4.0 secure KVM switches inoperable when physical tampering is detected
• Configurable device filtering – supports administrative configuration to filter USB HID devices
• Superior video quality – up to 4K** (3840x2160 @ 30Hz)
• Port selection via push-buttons and optional Remote Port Selector (RPS)

ATEN secure KVM switches are specifically designed to enforce stringent desktop security by keeping sensitive assets isolated while providing advanced user data protection and flexible administrative security management features. They are suitable for deployment in any industry that needs to handle sensitive, confidential, or proprietary information, or implement multi-level security on separate networks, such as government and military agencies, healthcare providers, banking and finance institutions, and more.

ATEN secure KVM switches are NIAP¹-certified and compliant with NIAP PPv4.0 (protection profile for peripheral sharing switch, version 4.0) requirements, satisfying the latest security requisites set by the U.S. Department of Defense for peripheral sharing devices. Compliance ensures maximum information security while sharing a single set of USB² keyboard/mouse, monitor, and speakers between multiple computers.

Conformity with Protection Profile v4.0 certifies that other USB peripherals cannot be connected to the console ports of the secure KVM switch, and that only a keyboard and mouse are accommodated, therefore providing high-level security, protection and safekeeping of data.

ATEN secure KVM switches hardware security includes tamper-evident tape, chassis intrusion detection, and tamper-proof hardware, while software security features include restricted USB connectivity – non-HIDs (human interface devices) are ignored when switching, an isolated channel per port that makes it impossible for data to be transferred between secure and unsecure computers, and automatic clearing of the keyboard and mouse buffer when switching port focus.

By combining physical security with controlled USB connectivity and controlled unidirectional data flow from devices to connected computers only, ATEN secure KVM switches offer you the means to consolidate multiple workstations of various security classification levels with one keyboard, monitor and mouse (KVM) console.

ATEN CS1148D4 PSD PP v4.0 secure KVM switch is specifically designed to meet the stringent security requirement of secure defense and intelligence installations. ATEN CS1148D4 PSD PP v4.0 secure KVM switch is compliant with PSD PP v4.0 (Protection Profile for Peripheral Sharing Device, Version 4.0) standard certified by the National Information Assurance Partnership (NIAP), assuring maximum information security by isolating computer sources and peripherals while sharing a single set of keyboard, mouse, monitor, and speakers between connected computers of various security classifications.

ATEN CS1148D4 PSD PP v4.0 secure KVM switch provides isolation between computer sources and peripherals while sharing a single keyboard, mouse, monitor, and speaker set between connected computers of various security classifications. Compliance with PSD PP v4.0 ensures peripheral sharing capabilities provide maximum user data security when switching port focus, preventing unauthorized data flows or leakage between connected sources.

ATEN CS1148D4 secure KVM switch (PSD PP v4.0) provides key protections including isolation and unidirectional data flow, restricted peripheral connectivity and filtering, user data protection, configurable device filtering and management, and always-on tamper-proof design, which keeps sensitive assets isolated and provides advanced security and a user friendly design for instantly secure deployment.

To enhance security, ATEN CS1148D4 PSD PP v4.0 secure KVM switch only offers manual switching methods including front panel pushbuttons and optional remote port selector (RPS). With multi–layered security, ATEN CS1148D4 ensures high-level desktop security and data safekeeping for applications such as government and military agencies, healthcare providers, banking and finance institutions, and other organizations that often handle sensitive or confidential data on separate networks. 

Multi-Layered Security
• Always-on chassis intrusion detection – renders the ATEN PSD PP v4.0 secure KVM switch inoperable when physical tampering is detected
• Tamper-evident labels – provides visual indication of any attempt to access the ATEN PSD PP v4.0 secure KVM switch's internal components
• Non-reprogrammable firmware – prevents reprogramming the ATEN PSD PP v4.0 secure KVM switch's firmware
• Restricted peripheral connectivity – non-authorized HIDs (human interface devices) and video are rejected
• Port selection via pushbuttons and/or optional remote port selector (RPS) only, to enhance security
• LED indicators for peripheral filtering and KVM security status
• Strict audio filtration protects against audio leakage
• Rugged metal enclosure

Data Channel Isolation and Unidirectional Data Flow
• True data path isolation – data cannot be transferred between computers
• ATEN PSD PP v4.0 secure KVM switch controls and isolates data flow between console devices and connected computers
• Unidirectional data flow between console devices and the selected computer is ensured
• Supports analog audio (speakers only)*

User Data Protection
• ATEN PSD PP v4.0 secure KVM switch's keyboard/mouse data is automatically deleted after transmission and automatically purged when the KVM port focus is switched

Security Management
• Supports administrative configuration of keyboard/mouse ports filtering to reject specific USB HID devices
• Provides administrative functions for authorized administrators to audit KVM log data

Superior Video Quality
• Superior video quality – up to 4K** (3840x2160 @ 30Hz)
• Video DynaSync™ – exclusive ATEN technology eliminates boot-up display problems and optimizes resolutions when switching among different sources
