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. GitHub: cacheguard/CacheGuard-OS
