ENTERPRISE SCALE

More agents.
Same control.

Expand what your teams can do with AI. Keep connected agents within the authority you grant, with verifiable proof of their actions.

Illustrative office floor with people working across several staffed workstations; agent labels are added separately to identify example execution paths. — Illustrative deployment. Protection applies to connected execution paths.

Illustrative simulation

Same agent. Two requests. One boundary.

Choose an agent interface and action, then compare a request within the example mandate with one outside it. These are simulated workflows, not live integrations.

2 / CHOOSE THE ACTION

Simulation only. No money, data or system changes. Receipt previews are illustrative and are not signed evidence.Inspect real evidence and verification →

BUILT FOR THE AGENT STACK YOU ALREADY RUN

Connect the agents your team already uses.

Implemented packages and supported MCP hosts. Each action needs its own protected execution path; connecting a host does not gate every tool.

An execution boundary

Permission checked where the action happens.

Monitoring records activity. Model guardrails guide or check behavior. Fidacy requires authorization at the connected executor before it acts.

01 / MANDATE

Set explicit limits.

A signed mandate defines who may act, on which resource, within which amount and time limits.

02 / EXECUTOR

Require valid authority.

The protected executor checks a matching, unexpired authorization before making the call. No valid authorization, no execution through that path.

03 / RECEIPT

Verify the decision.

Signed receipts preserve allowed and denied decisions so their integrity and origin can be checked independently.

Protection applies only to actions routed through an integrated enforcement path. Observing an agent does not mean its tools are gated.

Access is not authority

A tool connection is not a blank cheque.

An agent may have payment access without permission to pay any supplier. A support agent may issue refunds without authority to refund any amount.

PAYMENTS

Right tool. Wrong destination.

A payment to an unapproved payee must stop, even when the agent has valid API credentials.

REFUNDS

Right customer. Wrong amount.

A refund above the approved limit must not reach Stripe through the protected refund executor.
