taqi2508f-ui/Network-Security-Audit-Tool ? reverse-engineered prompt

Build me a terminal based network security audit tool in pure Python that I can run on networks I own or have permission to test.

I want it to guide me through the whole process, starting with confirming authorization, then discovering live hosts on a subnet, scanning the hosts for common open ports, and flagging risky services with clear severity labels like critical, high, medium, and low. It should also give me simple remediation advice for each issue, like firewall commands and basic hardening tips I can copy and paste.

Make the interface feel polished and easy to follow, with progress updates and colored output in the terminal. If possible, let it export a full report in Excel, and if that is not available, fall back to CSV and JSON. It should work as a single Python file with no required extra dependencies, and use current best practices from the Python standard library.
