SM20N−3 is a secure 2−port KM switch. It enables users to share peripherals – keyboard, mouse, audio and USB − between two different security−level networks/computers while isolating all hosts and protecting against data leakage and malicious attacks through shared peripherals. SM20N−3 provides the highest possible isolation between connected computers and is NIAP Common Criteria Protection Profile version 3.0 (PP3.0) certified.

• Highest Security by Design — NIAP Common Criteria Protection Profile version 3.0 (PP3.0) certification for peripheral Sharing Switch (PSS) devices.
• Work Freely Without Compromising Security — Control classified and non–classified computers without compromising security.
• Prevent Information Leaks — Block peripheral exploits, information leaks, eavesdropping, signal transmission, computer malware, hardware and firmware tampering.
• Filter USB Peripherals — Allow or block specific USB devices based on VID/PID characteristics.
• Smooth Switching Between Computers (Virtual Display Technology) — Automatically switch all peripheral control from one computer to another by dragging the cursor between each computer’s display border.
• Keyboard Lock Indication — Caps Lock, Num Lock, and Scroll Lock indication on front panel.
• Multiple Display Layouts — Associate the cursor with each computer based on how its display is aligned (vertically or horizontally).
