Short answer: different job. Harden Windows Security changes your machine — it applies a hardened baseline using only official Microsoft features, and it's excellent at that. Apotrope never changes anything: it's a read-only assessor that scores any Windows box against CIS Benchmarks and hands you a report with plain-English fixes. Audit with Apotrope, harden with Harden Windows Security or Group Policy, then re-audit. They compose.
Harden Windows Security, by Microsoft MVP Violet Hansen (HotCakeX), ships two signed MSIX apps on the Microsoft Store. Harden System Security applies hardening to Windows using only built-in Microsoft features, then verifies workstation compliance against its baseline and reports a security score. AppControl Manager is the deepest free WDAC / App Control for Business tooling around. Its supply-chain posture — SLSA build attestations, signed releases, a relentless release cadence — is a genuine strength.
Apotrope solves the other half of the problem: knowing where a box stands against a published external benchmark. It's one portable .exe (or pip install apotrope), read-only by design — no install, no registry writes, no network — and it scores against an external yardstick: the CIS Microsoft Windows Benchmarks (Windows 11 v5.0.0 / Windows 10 v4.0.0, selected automatically from the OS build). That matters most when the machine isn't yours to change: a client box during an assessment, a fleet you're only allowed to measure, an audit deliverable that needs a recognized benchmark behind it.
If you want your own machine hardened and kept hardened, use Harden Windows Security — it's the best free option for that job, and Apotrope deliberately doesn't compete with it. If you need to measure a machine against a published benchmark without touching it, that's Apotrope: drop one exe on the box, get a scored, CIS-mapped, emailable report, leave nothing behind. Then hand the fixing to Harden Windows Security, Group Policy, or the paste-ready PowerShell in Apotrope's own report — and re-audit to prove it worked.
