" summary

A script-based framework runs read-only shell and PowerShell collectors (plus Visual Basic for Windows Server 2008) against a host CSV, normalizes outputs into one CSV and generates an Excel with per-host tabs and a risk sheet. The codebase is about 3,800 lines of script, scans take ~1–3 minutes per host, and a 42-VM inventory drops from ~3–4 weeks of manual work to ~2 hours. Planned next steps: hypervisor discovery and scaffolded OpenTofu and Ansible output.
