Key takeaways

  • DuoClave manages two isolated networks at once on up to two displays, where a traditional secure KVM reaches one network at a time.
  • Operators switch between four or eight computer sources using Key Press Seamless Cursor Switching, front panel buttons, or an optional remote control.
  • Designed for government and military networks configured to meet NIAP Protection Profile PSD 4.0, with optical data diodes and an always-on, battery-backed anti-tamper circuit.
  • Ten predefined monitor layouts cover most multi-display setups with a keyboard shortcut, and every unit is TAA-compliant and assembled in the USA.

Government, military, financial, healthcare and energy networks cannot treat data security as an afterthought. The Belkin DuoClave Secure KVM Series is built for exactly those desks: it keeps sensitive networks physically isolated while one operator controls multiple computers from a single keyboard, monitor, and mouse.

What is the Belkin DuoClave Secure KVM switch?

Today's evolving digital landscape demands that the government, military, financial, healthcare and energy industries optimize cybersecurity for their networks. The Belkin DuoClave Secure KVM Series is a no-compromise solution for safeguarding sensitive information. This advanced secure KVM (Keyboard, Video, Mouse) technology is designed specifically for environments that cannot afford to approach data security as an afterthought.

The DuoClave SKVM switch ensures network systems are protected from unauthorized access while allowing seamless control over multiple computers. Its user-friendly interface and switching capabilities allow operators to toggle between systems without compromising on security. DuoClave SKVMs provide the stringent safeguards required by today's IA (Information Assurance) computing requirements, functioning as a vital barrier against potential cyber threats. Whether you're in finance, government, or any sector that handles confidential data, the Belkin DuoClave Secure KVM provides peace of mind with convenient functionality.

How the DuoClave SKVM works

Traditional SKVMs allow access to one network at a time on up to two displays. The Belkin DuoClave SKVM Series enables simultaneous secure management of two networks from two independent displays. DuoClave is designed to optimize surveillance of two active networks at the same time.

Featuring ten predefined monitor layouts, DuoClave offers a setup for most use cases with just a keyboard shortcut. Whether you're working with two, three, or four connected monitors, our presets make it easy to navigate and customize your workspace, complete with perfectly defined screen borders for maximum productivity.

Operators have the ability to securely switch between four or eight computer sources while simultaneously viewing two networks on different monitors. Belkin's DuoClave SKVM Series securely switches between sources via Key Press Seamless Cursor Switching (KPSCS). Deliberate enclave switching with KPSCS will transition the keyboard and mouse control from one channel to the next when the mouse cursor crosses a display border onto the adjacent display, while the user depresses the Control key. The user may also use the front panel buttons, or the optional remote controls, to switch between channels.

The user switches control between the green and red network sources by moving the mouse cursor across monitors. The DuoClave device indicates active channels with corresponding green and red indicators.

DuoClave key features and benefits

  • Designed for use on government and military networks configured to meet NIAP Protection Profile PSD 4.0.
  • Securely multitask: efficiently manage and view two active networks simultaneously on up to two displays.
  • Situational awareness: preconfigured port coloring on the front panel facilitates channel identification and reduces operator errors. On 4- and 8-port SKVMs, port 1 is green, port 2 is white, port 3 is red, and all others are white.
  • Key Press Seamless Cursor Switching (KPSCS): keyboard control follows the mouse as the cursor crosses from one physical display to the other with a keyboard key held down.
  • Lag-free, real-time switching: a hardware-based solution eliminates keyboard and mouse delay when switching between ports, for a fluid and intuitive experience.
  • True data path isolation: optical data diodes prevent peripherals from being used to breach systems.
  • Innovations for optimal user experience: compatible with the optional Belkin SKVM Remote Control series including 4- and 8-port variants, TAA docks, mounting solutions, and the extender portfolio, decluttering the desk while keeping the operator aware of the security domain they are working in.
  • Tamper-proof system: an always-on, battery-backed, active anti-tamper circuit protects the unit from a breach while in transit and after deployment.
  • TAA-compliant: assembled in the USA, with U.S.-based technical support and secure packaging that ensures integrity from factory to user site.

DuoClave Secure KVM: Your Questions Answered

What is a secure KVM switch?

A secure KVM (Keyboard, Video, Mouse) switch lets one operator control several computers on separate, isolated networks from a single keyboard, monitor, and mouse, with hardware safeguards that stop data from crossing between networks. Belkin builds its Secure KVM range for government, military, and other high-assurance environments. Learn more on our Secure KVM overview.

What is the difference between the DuoClave and MultiClave Secure KVM switches?

The DuoClave manages two active networks on up to two displays at once, ideal for watching two enclaves side by side. The MultiClave scales further, controlling up to eight isolated networks on dual monitors. See the MultiClave Secure KVM switch for the higher-count option.

How many computers can the DuoClave switch between?

DuoClave models securely switch between four or eight computer sources while viewing two networks on separate monitors, using Key Press Seamless Cursor Switching. The 4-port DisplayPort DuoClave is the entry point in the series.

Is the Belkin DuoClave NIAP certified, and where is it made?

Yes. DuoClave is designed for networks configured to meet NIAP Protection Profile PSD 4.0, with an always-on, battery-backed anti-tamper circuit, and every unit is designed and assembled in the USA with U.S.-based support. The 8-port DisplayPort DuoClave extends the same protection to more sources.
