Pricing FAQ

Is the free tier limited in any way?

No. Every feature works on one machine with zero restrictions — monitoring, scheduling, reports, fixes, compliance mapping, all of it. There's no trial period, no feature gates, no "upgrade to unlock." Free means free.

What exactly is Pro for?

Pro is exclusively for fleet management — when your organization needs a central control plane to monitor and manage multiple Windows machines. If you only have one machine, you never need Pro.

Does WinSentinel send anything to the cloud?

No. Every audit module is deterministic .NET code hitting real Windows APIs — zero network calls. The optional AI advisor talks to a local Ollama instance. No OpenAI, Anthropic, or any third-party LLM is ever called. On Pro, only machines you explicitly connect to the fleet dashboard push results — and you control redaction.

How does Pro node pricing work?

Pro scales by how many machines report to the fleet dashboard: 25 nodes = $29/mo, 100 nodes = $79/mo, unlimited = contact us. You pick the tier that fits; no per-seat math.

Is there an annual plan?

Yes — pay annually and save 17%. The 25-node tier is $290/year (effectively $24.17/mo) and the 100-node tier is $790/year. Toggle the billing switch at the top of this page to see annual pricing.

Can I get a refund?

Yes — 30-day, no-questions-asked refund on Pro. Cancel directly in Stripe (link in your purchase receipt) and we'll auto-refund the last charge.

When does billing actually start?

Stripe Checkout is being wired up right now. If you click "Get Pro early access" before launch, you'll go straight to the waitlist and get a one-time invite when Pro opens.
