The project
DefendOS is a global VPS surveillance agent. It inspects the machine, access paths, services, ports, logs and suspicious signals, then can ask Codex to investigate in read-only mode.
Technical angle
The public README describes a chain from timer, email command or dashboard action to healthcheck, heuristics, Codex investigation, final result, email alert and local dashboard update.
What it proves
This project shows mature agentic automation for infrastructure: the agent helps diagnosis, while risky actions stay bounded.
