LinkGuard is a network security solution from Blue Ridge Networks designed to protect IT and OT environments through secure remote access, network segmentation, and cryptographic data protection. The product is offered in two variants: - **LinkGuard Enterprise**: Targets organizations requiring secure remote access, isolation, segmentation, and cryptographic protection for critical assets and operations. - **LinkGuard Express**: Designed for rapid deployment and ease of implementation, targeting organizations that need immediate protection with minimal setup overhead. A core component of LinkGuard is **CyberCloak**, which combines network obfuscation, cryptographic transport, multi-factor authentication, and infrastructure segmentation to protect critical assets and sensitive data. CyberCloak operates across four functional pillars: - **Isolate**: Limits the scope of a security breach through segmentation, restricting unauthorized access to sensitive data. - **Conceal**: Hides critical assets using network obfuscation to reduce exposure. - **Encrypt**: Protects data transmitted across unknown or hostile networks using cryptographic transport. - **Authenticate**: Enforces multi-factor authentication to restrict unauthorized access to networks and devices. LinkGuard also includes support for **quantum resilience**, with a forthcoming "LinkGuard Quantum" variant intended to protect data against future quantum computing threats. The **RemoteLink80** hardware component provides endpoint protection for secure remote and cellular communications. LinkGuard is positioned for use cases involving both enterprise IT environments and operational technology (OT) environments, including industrial and critical infrastructure contexts.
