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
SudoRank serves as an interactive platform tailored for DevOps engineers, SREs, and system administrators to repair authentic malfunctioning systems on operational Linux virtual machines and Kubernetes clusters, rather than relying on simulations or containers.
With a total of 750 challenges spread across 15 distinct tracks, participants can engage in areas such as Linux, system administration, storage solutions, scripting, networking, web server management, VPN setup, Docker, Kubernetes, Terraform/Ansible, CI/CD processes, GitOps, server hardening, incident response, and offensive security.
Every challenge offers a flawed environment with root access, allowing users to resolve issues using their preferred methods, while the auto-grading feature evaluates the actual system state rather than the approach taken.
Notable features include authentic multi-node Kubernetes clusters, a real-time AI tutor that monitors terminal activity, progressive hints, interview preparation, incident simulations, session recordings, achievement badges, and competitive leaderboards.
The platform offers free access to 8 tracks with 281 challenges, while the Pro version at $8 per month grants access to 13 tracks and 652 challenges, and the Pro+ version at $15 per month provides all 750 challenges along with unlimited AI tutoring support.
This comprehensive setup not only enhances practical skills but also prepares users for real-world scenarios they may encounter in their careers.
