HardeningKitty
ToolHardeningKitty is an open-source PowerShell tool from scip AG that audits and hardens Windows against a long list of benchmarks, then writes the results to a tidy CSV you can actually hand to an auditor. Run it in Audit mode to see where you stand, Config mode to fix the drift, or the aptly named HailMary mode when you want an entire hardening list applied in one go. Signed, actively maintained, and refreshingly quick to point at a machine.
