Description
CacheGuard-OS is an open-source Linux-based UTM gateway appliance OS that has been in active development since 2002. It is designed to run on commodity x86 hardware and act as the default route between an internal network and the internet, replacing the ISP-provided router as the traffic checkpoint.
The stack integrates: Squid (web cache and proxy), ClamAV (web antivirus), ModSecurity (WAF), StrongSwan (IPsec/IKEv2 VPN), IPRoute2 (QoS and WAN load balancing), NetFilter (stateful firewall), SSL inspection, and URL filtering. All components are configured through a web-based admin interface rather than directly, making the platform accessible to operators without deep Linux expertise while remaining auditable by those who want to inspect the underlying configuration.
The OS has been open-source since its first release — source ships on every installed appliance. It was recently published publicly on GitHub to make the codebase easier to browse and audit.
Target deployments are small to medium networks — SMBs, schools, and branch offices — where a commercial UTM appliance is overkill on budget but the threat surface is the same. Runs on bare metal or common hypervisors (VMware, VirtualBox, KVM, Hyper-V). No vendor lock-in, no subscription, no licence cost.

Description
Blue Ridge Networks offers LinkGuard, a solution focused on cybersecurity and network segmentation aimed at protecting essential IT and operational technology (OT) assets by embedding them within a "stealth" overlay that effectively isolates, conceals, encrypts, and authenticates access to these critical systems. Utilizing a zero-trust, high-assurance cryptographic overlay known as CyberCloak, LinkGuard establishes distinct secure Layer-2 network enclaves that separate safeguarded systems from both the broader network and each other, significantly minimizing the attack surface while avoiding any modifications to the current network setup. This innovative approach allows LinkGuard to function as an overlay, eliminating the need to replace existing network infrastructure or reconfigure IP addresses, thus facilitating rapid deployment through the use of pre-configured cryptographic devices such as BorderGuard and/or client-side agents. As a result, LinkGuard enables secure remote access across various distributed locations, providing an efficient and robust solution for modern cybersecurity challenges. Its design underscores the importance of maintaining a secure environment while leveraging existing technologies.
