Byos Secure Cluster Edge is a hardware appliance that provides microsegmentation for datacenter server racks. It installs directly into a server rack and acts as a secure gateway between workloads and the broader network, without requiring network redesign or software agents. The device provides 10 downlink ports, each forming an isolated microsegment with dedicated access controls. Traffic between segments is controlled and monitored at the hardware level. Once installed, it enforces a Zero Trust perimeter around each connected device or VM, preventing lateral movement between segments and reducing blast radius in the event of a breach. Key use cases include: - Reducing network complexity in datacenters by handling segmentation without additional hardware - Securing multi-tenant environments through physical separation within a single rack - Containing lateral movement during a security breach by isolating zones by application, department, or sensitivity level - Supporting secure development and testing environments by isolating test workloads from production - Optimizing resource allocation for hybrid workloads (e.g., HPC vs. legacy apps) - Simplifying compliance for regulated industries by providing auditable, hardware-enforced boundaries (e.g., isolating patient data in healthcare) The device is FIPS 140-2 validated and manufactured in the USA with a certified supply chain. It requires no software agents, no network reconfiguration, and is described as plug-and-play. Access to connected resources is provided without exposing servers directly to the internet.
