# Capability modules

> Catalog of Clausum integration modules — who uses each and where to learn more

Clausum is sold and integrated as **modules**. Your segment guide orders them; this page maps each capability to client types and deep-dive docs.

## By integration layer

| Layer                 | When it runs                           | Modules                                           |
| --------------------- | -------------------------------------- | ------------------------------------------------- |
| **Prevention (sync)** | Before money moves                     | Pay-in assess, Payout assess, Browser SDK         |
| **Async (events)**    | After or parallel to payment lifecycle | Outbound webhooks, Inbound ingest, Stripe adapter |
| **Operations**        | Human workflows & compliance           | Cases, Report fraud, Protection UI, Monitor       |
| **Institutional**     | Bank / network contracts               | Submerchants (PSP), Fraud network, Managed intel  |

<Warning>
  **Prevention first.** Post-payment webhooks and ingest alone cannot block checkout fraud — you must call assess before capture or payout.
</Warning>
