How it works

Every Payrexx action
governed end-to-end.

Cerebral OS isn't a connector. It's the execution layer that sits in front of Payrexx — adding governance, dry-run safety, and a full audit trail to every operation.

Governance first
Every verb carries a risk classification. High-risk writes require explicit approval gates before they execute in production.
Dry-run safe
Simulate any Payrexx action before it touches production. See exactly what would happen before a single real call is made.
Immutable audit trail
Every Payrexx action is logged — what ran, what changed, who approved it, when it happened. Full history on every verb, forever.
