In secure federal and defense environments, maintaining physical separation between classified and unclassified networks is non-negotiable. ClearCube’s ClientCube family provides the industry’s most advanced multi-domain isolation, allowing operators to switch seamlessly between SIPRNet, NIPRNet, and JWICS from a single, consolidated desktop footprint.
Whether operating inside a SCIF or managing remote secure enclaves, ClearCube delivers SIPR/NIPR hardware isolation that exceeds NIAP 4.0 standards and NIST 800-207 Zero Trust mandates.
Our Multi-Level Secure KVM Solutions provide unparalleled protection for your sensitive data and systems. Switch between multiple computers with a ClearCube ClientCube multi-domain switching device. The ClientCube provides and ‘all-in-one’ solution for clearing clutter and condenses the zero clients and switch into one unit that requires only one plug.
Our advanced encryption and authentication methods provide an extra layer of security, making sure your data is safe from cyber threats. With easy remote access and control, our secure KVM solutions are perfect for government, military, and financial organizations looking for the highest level of security.
Enclosed SKVM is NIAP-certified to meet Protection Profile PSS Ver. 4.0
Stateless, No OS, No Storage, No Memory
Integrated SIPR/CAC Reader

This demonstrates a four separate network workstation installation before and after implementing our ClientCube NET-4 Secure KVM. Simply switch workstations with a tap of a button.
Switch between multiple devices, servers, and monitors from an all-in-one computing device.
For high security sites, ClearCube has developed a family of Multi-Level Security KVM Solutions that include the ability for DisplayPort switching, remote KVM access, and offers multi-domain switching.
We adapt advanced technology and standard, off-the-shelf products to meet unique customer requirements. ClientCube KVM solutions are great for military, media, healthcare, and call center situations where the device can be remote mounted in a centralized management location and paired with a remote control. Each individual zero client has dual-monitor capability and each ClientCube can feature various configurations. Our KVM switches ensure that only authorized users have access to sensitive information. Our advanced encryption and authentication methods provide an extra layer of security, making sure your data is safe from cyber threats.
Portable or Fixed Position Secure KVM Switching.
Whether you are using a ClientCube in a fixed workstation or incorporating them into a fly-away kit for portable use, the ClientCube will create a secure and easy user experience, from set up to take-down. There is no other product that can make portable use of a secure KVM as simple, easy, and quick as the Net-4 SFF ClientCube. This unit takes the 48 feet of cables and cords that would normally be required for separate devices and reduces that tangled, heavy mess down to a single power cord and an organized set of one-foot-long internally housed cables.

Our solutions provide true physical data isolation. By utilizing integrated Zero Clients or Trusted Zero Clients, there is no shared memory or storage between enclaves. The integrated NIAP PP 4.0 Secure KVM (or KM) ensures that video, keyboard, and mouse data never bleed between classified and unclassified ports. Each connected computer has its own dedicated data path; the KVM does not allow data to flow between them.
Designed for both fixed command centers and rapid-deployment fly-away kits, the ClientCube NET-4 SFF and NET-8 series reduce cable clutter by 90%. We eliminate the “spaghetti” of 48+ feet of cabling, replacing it with internally managed connections that meet strict EMI/TEMPEST requirements for use inside a SCIF.
Move beyond software-only security. Our Trusted Zero Clients (TZC) feature a hardware root of trust, verifying firmware integrity before allowing connection to a secure server. This fulfills the “Endpoint Integrity” requirements of NIST 800-207 Zero Trust Architecture.

ClearCube Zero Clients contain no OS, no storage, and no memory. If a device is compromised or physically removed, no mission data is at rest.
High-security smart card readers are mapped directly to the active channel, ensuring Multi-Factor Authentication (MFA) persists across switching.
Every ClientCube is designed and assembled in the USA, ensuring a secure supply chain for DoD and Federal procurement.
For environments requiring ultra-minimal desktop footprints, our SW2D technology extends secure KVM access over long distances with zero latency.
