Control flow

From a real user session to a signal the team can act on

Payment page risk often appears in the browser before it is visible in backend logs: a script changes, a form behaves differently, or a third-party call enters the checkout path. The flow below shows how Cartelta turns that client-side moment into structured context for security, product owners, and audit work.
