    Hi HN, I spent the past year building this in my spare time because I got tired of enterprise security tools that cost $50K/year and don't understand Linux. TheProtector is a comprehensive security monitoring tool that actually runs on the systems we use (Linux) instead of being a Windows-first afterthought. Built it entirely on a $500 laptop because I believe good security shouldn't require unlimited budgets. Features: - Real-time process, network, and file monitoring - YARA malware detection with custom rules - eBPF kernel monitoring (when available) - Behavioral baseline…

    I created Firezone to make it easier to host and manage your own WireGuard VPN server. While working at Cisco as a security automation engineer I experienced a lot of unnecessary pain managing secure network-level access into our cloud VPCs. I tried OpenVPN Access Server but I personally feel that security software should be open source to be validated (and improved) by the community. I discovered WireGuard and quickly fell in love with it, but soon found managing the peer configs to be a bit tedious and error-prone. So I built some convenience functionality on top, added a simple Web UI,…

    Hi HN! I'm Jarek, and I've built this tool that allows publishing .local domains on the local network using mDNS. It also has a reverse proxy that handles HTTPS termination and port forwarding. I'm working on adding more features, like an index page with all available domains or allowing proxy redirects, so you could redirect from HTTP to HTTPS. Let me know if you have any questions or feedback!

    Hi HN, I've built an app for macOS that allows performing common SSH operations on Linux servers using a native GUI. The problem: Managing multiple Linux servers usually means juggling terminal windows and copy-pasting snippets/scripts. After dealing with tens of production/staging VPSes at previous jobs, I realized there had to be a better way for common operations I did on a daily basis than my collection of bash snippets. Features: - Quickly switch between different servers. Tag servers with arbitrary key values for easy search. - Real-time dashboard with CPU/memory graphs,…

    We just open-sourced CargoWall - a lightweight eBPF firewall for GitHub Actions. We originally built it to stop LLM agents from connecting to untrusted domains. After recent GitHub Actions supply chain compromises like the Trivy attack, we realized it'd work well for blocking untrusted connections from CI runners too. It uses iptables DNAT to redirect all outbound port 53 traffic to a local DNS proxy, which checks each query against a hostname allowlist before forwarding. Resolved IPs from allowed responses are inserted into eBPF LPM trie maps, and a TC egress classifier attached to the…
