PrefectOS is the operating system that stands between every AI agent and your real systems — banking cores, SAP, Salesforce, code. Deny-by-default policy, human gates on anything irreversible, and a signed receipt for every single call.
THE TOWER · CLEARS EVERYTHINGEverything an agent does passes through one spine. The spine has four jobs, and none of them involves trusting the agent's good intentions.
Deny-by-default allowlists per agent — actions and resources, written by you. Unknown agent, unknown action, unknown target: refused before execution.
Money movement, customer contact, master-data edits — always held for a named person. Approval satisfies a gate. It never rewrites policy.
Every allow, hold, deny and outcome — hash-chained and cryptographically signed. Tear one out and the chain says so. Forge one and the signature says so.
One switch freezes one agent, one industry, or every non-human worker you have. Even pressing the switch leaves a receipt — try the lever above.
New agents start supervised, like new employees. Clean approved work earns wider limits. One incident sends them back to probation — and the record says who cleared it.
Proposes only. Touches nothing.
Works, but a human signs every action.
Routine work flows; risky work still gates.
Earned, revocable — and always-gated actions still gate.
This is a live hash chain, the same mechanism inside PrefectOS. Click any line to alter it, and watch the chain call you out. Then restore it.
Each pack ships agents, policies and gates for one world. Flip the switch and they're governed from the first call — the flip itself is receipted.
Loan document pipelines live today; a governed doorway to the core.
Claims intake to settlement, with settlement always behind a human.
AP automation; payment runs gated; vendor bank edits in nobody's book.
CRM hygiene flows free; anything a customer sees waits for a person.
Coding agents ship PRs; deploy rights are earned, never assumed.
Our favourite demo: an approved payment posts in seconds — then the same agent, with the same approver, tries to change where a supplier's money goes. The door simply never opens.
