Reduce transaction liability
Prevent uncontrolled purchases, refunds, and policy abuse as AI agents transact across your platform.
Control delegated authority
Define and enforce spending, refund, and access limits in one place for agents, customers, and services.
Know your exposure in real time
What can this AI agent execute right now? Get a clear answer during disputes, fraud spikes, or compliance reviews.
“You’ve got to track and enforce who can access data and when. If you don’t do this correctly, you potentially open up unauthorized access.”
Edgar Rivera, CTO
Agents don't get to decide. Your access policies do.
Review each AI agent purchase and refund request against the access policy before money moves.
How Cerbos works
Every request is verified
Identity systems verify who the customer or AI agent is. Cerbos decides what they are allowed to do at the moment a transaction is executed, across checkout, refunds, subscriptions, APIs, and internal tools.
Access decision in real time
Every purchase, refund, or update request is evaluated against centralized access policies before it is approved or denied. The same policy layer applies to human users, AI agents, and backend services.

The cost of unchecked agent access
Uncontrolled automated purchases
AI agents can execute purchases at scale without transaction-level limits, increasing fraud exposure and merchant liability.
Refund and promotion abuse at machine speed
Automated refund flows and promotion stacking bypass static rules, creating financial leakage across checkout and post-purchase workflows.
Over-permissioned delegated wallets
AI agents inherit broader access than required, enabling high-value orders, bulk purchases, or cross-account actions.
Inconsistent access policy across channels
Different rules across storefront, APIs, marketplaces, and support tools create enforcement gaps and audit risk.
No clear decision trail
Without centralized policy evaluation, merchants cannot prove which rule allowed a purchase or refund during disputes or chargebacks.
