Byos Secure Embedded Edge is an embeddable System on Module (SOM) designed to provide hardware-enforced network security at the edge. The module connects to a laptop via the M.2 port, replacing the native Wi-Fi module and acting as the first point of contact for all network traffic. Operating as a Retransmission Device (RTD), it decouples the network connection from the laptop's operating system, creating a microsegment that isolates the device from the broader network. This isolation prevents lateral movement and eliminates the attack surface exposed to malicious network activity, without relying on any OS-level software. The module supports wired and wireless connectivity including Wi-Fi, Ethernet, Cellular, and PCI-E, and consumes 1–2 watts of power. It operates independently of the host OS and cloud services, meaning endpoint protection remains active even if the OS is compromised or endpoint software is bypassed. Key capabilities include Asset Cloaking, which makes the connected device invisible to other devices on the local network, and Captive Portal Protection for enhanced security on public Wi-Fi networks such as those found in airports or hotels. The product is managed through the Byos Management Console, which provides centralized policy enforcement and administrative control. It meets NSA's Commercial Solutions for Classified (CSfC) requirements and its cryptographic module is FIPS 140-2 validated (Certificate #4964). Applicable use cases span laptops, desktop workstations, medical devices, industrial controllers, security cameras, IoT devices, servers, POS devices, robots, and networking equipment.
