Questions

Frequently asked

What counts as a request?

Any signed action request processed by Sentinel counts, whether it is allowed, reviewed, or denied.

Can I switch plans later?

Yes. Upgrades apply immediately. Downgrades apply at the next billing cycle.

Why is Developer limited to layers 1–6?

Developer is designed for evaluation. Production governance features like execution, reporting, and forensics start on paid tiers.

Does Startup support production use?

Yes. Startup is the first paid production tier, with approval workflow, action reports, and audit logging.

What makes Business different?

Business adds the full governance story: execution ledger, live timeline, replay & forensics, and security scoring.

How is Enterprise priced?

Enterprise pricing depends on deployment model, agent count, request volume, retention, compliance requirements, and support level.

Every agent. Every action.
Governed.
