Kramer K304E HighSecLabs Secure 4-Port KM Switch

The K304E is a secure 4-port KM Switch designed for high-security environments where controlled sharing of keyboard and mouse between multiple computers is essential. It delivers effortless collaboration across four security-level sources while delivering the highest possible isolation between each connected system. Leveraging HSL Virtual Display Technology (VDT), the K304E switches between sources seamlessly, enabling smooth operation without compromising the strict security boundaries required in Sensitive Compartmented Information Facilities (SCIFs) and other fortified workspaces. This device is purpose-built for organizations that demand uncompromising data separation, robust access control, and reliable input device switching from a single console.

With four distinct channels, the K304E makes it possible to manage multiple security domains without physically swapping cables or compromising audit trails. Operators gain the convenience of a centralized control point while administrators benefit from hardware-enforced isolation that minimizes the risk of data leakage, cross-contamination, or unintended data exfiltration between sources. The K304E is not just a KM switch; it is a secure, auditable control point that integrates into hardened networks and security policies. Its compact design, rugged construction, and secure switching philosophy make it an ideal fit for secure lab benches, mission-critical workstations, and compliant office environments where security requirements are non-negotiable.

Whether your workflow involves switching between government-grade workstations, secure test benches, or multi-domain research environments, the K304E provides reliable, intuitive operation. Expect fast, lossless switching that preserves input latency, ensuring that operators experience responsive keyboard and mouse control during critical tasks. The combination of four-channel support, strong isolation, and Virtual Display Technology positions the K304E as a leading choice for organizations that prioritize security, performance, and ease of use in equal measure.

Key benefits include effortless cross-domain switching, enhanced auditability, and reduced risk of cross-contamination between devices. The K304E is designed to integrate with existing security ecosystems, offering compatibility with secure peripherals and compliance-friendly features that support rigorous testing, certification, and deployment processes. For teams that require reliable, repeatable performance in secure environments, this KM switch delivers predictable behavior, minimal human error, and a clear path to scalable multi-system control.

As part of the HighSecLabs family, the K304E embodies a commitment to secure design principles and industry-leading isolation. It is built to withstand the rigors of daily secure operations, with attention to ease of deployment, consistent performance, and straightforward management. Operators can rely on the K304E to provide consistent, secure access to multiple machines from a single keyboard and mouse, all while maintaining a strict boundary between sources that is essential for compliant operations.

• Secure four-port KM switching: Share a single keyboard and mouse across four separate security-level sources or computers while maintaining strict source isolation to prevent data leakage.
• Highest isolation between sources: Hardware-enforced separation ensures that each connected system remains independent, reducing cross-domain risk in sensitive environments.
