Byos Network Hardening is a hardware-enforced network microsegmentation solution designed to replace traditional Jump Box architectures in hybrid and multi-cloud environments. It uses the Byos Secure Edge™ platform to isolate assets into individual microsegments, enforcing OSI Layer 1–5 protections to prevent lateral movement, ransomware spread, and exploitation of firmware vulnerabilities. The solution consists of three core components: - **Secure Gateway Edge™**: A plug-and-play hardware gateway that replaces the Jump Box, placing downstream assets into their own microsegment and rendering them invisible to the broader network. It enforces security across OSI layers 1–5. - **Management Console™**: A centralized control plane for provisioning and enforcing security policies across one or thousands of devices. Deployable as cloud-based or on-premise. - **Secure Lobby™**: A private, encrypted Software-Defined Networking (SDN) overlay that enables secure remote access without exposing assets to the public internet. Administrators can define networking "Zones" enforced at OSI Layer 2, enabling compartmentalization of sensitive resources. The platform supports controlled software-defined airgaps that allow immediate incident response lockdowns while maintaining visibility and connectivity. It also enables remote data collection from within air-gapped networks via the Secure Lobby™ SDN overlay. Byos hardware is FIPS 140-2 validated, manufactured in the USA, and uses a certified supply chain.
