About
CacheGuard-OS is a free, open-source Linux-based network security appliance OS that turns any standard x86 machine into a UTM gateway. It sits between your devices and your ISP router, becoming the checkpoint for all internet traffic — no IT team required.
Open-source since its first release, CacheGuard-OS includes: stateful firewall, web antivirus (ClamAV), URL filtering, SSL inspection, WAF (ModSecurity), VPN server (StrongSwan), web cache (Squid), QoS (IPRoute2), and WAN load balancing.
It installs on bare metal or any common hypervisor in under an hour. Configuration is handled through a web-based admin interface with no command-line expertise needed.
Built for small businesses, schools, and sysadmins who need production-grade network security on commodity hardware.

About
LinkGuard from Blue Ridge Networks is a cybersecurity and network-segmentation solution designed to secure critical IT and OT (operational technology) assets by placing them inside a “stealth” overlay that isolates, conceals, encrypts, and authenticates access to sensitive systems. LinkGuard uses a zero-trust, high-assurance cryptographic overlay (called CyberCloak) that creates separate secure Layer-2 network enclaves, segregating protected systems from the general network and each other, thereby dramatically reducing the attack surface without requiring changes to existing network infrastructure. Because LinkGuard operates as an overlay rather than replacing underlying networking or requiring reconfiguration of IP addressing, it can rapidly deploy using pre-configured cryptographic devices (like BorderGuard) and/or client-side agents, enabling secure remote access across distributed sites.
