WinSentinel vs NinjaOne: FAQ

Is WinSentinel an RMM tool like NinjaOne? +

No. NinjaOne is remote monitoring and management focused on patching and device administration. WinSentinel is security hardening: it audits 13+ security modules, scores posture, and auto-remediates misconfigurations. Patching keeps software current; hardening fixes how it's configured.

Can I use WinSentinel alongside NinjaOne? +

Yes. Many teams run an RMM for patching and deploy WinSentinel for configuration hardening and posture scoring on the same fleet.

How much does WinSentinel cost compared to NinjaOne? +

WinSentinel is free for unlimited use on a single machine. NinjaOne is RMM/patching software priced per endpoint. WinSentinel Pro - which adds fleet management across many machines - is $29/mo for up to 25 nodes or $79/mo for up to 100 nodes, with annual billing saving 17%.

Is WinSentinel really free? +

Yes. The CLI and every audit module are free and open source under the MIT license, installed with dotnet tool install --global WinSentinel.Cli. A single machine gets the full power - all audit modules, the real-time monitor, scheduled scans, and PDF reports - with no limits and no account required. Pro is only for organizations that want to manage many machines from one control plane.

Does it only work on Windows? +

Yes. WinSentinel is built specifically for Windows 10 and Windows 11 (and Windows Server). It uses native Windows APIs to audit configuration that cross-platform tools treat generically, which is why its hardening checks are deeper on Windows.
