# Data Leakage Issues

Sboxr captures all the DOM Communication performed by an application. It monitors the following communication channels:

* Ajax calls, this includes XMLHttpRequest and fetch API use
* Cross-window messages sent via postMessage API
* WebSocket communication

Sboxr then processes the data sent in these communication channels and identifies all the data leaked by the site on the client-side.

The following options exist for viewing the data leaked:

* [Sensitive Data Leaked](https://docs.sboxr.com/view-issues/data-leakage-issues/sensitive-data-leakage)
* [Data leaked via Communication channels](https://docs.sboxr.com/view-issues/data-leakage-issues/non-sensitive-data-leak)
* [Data leaked via Referrer headers](https://docs.sboxr.com/view-issues/data-leakage-issues/non-sensitive-referrer-data-leak)
* [All Data leaked via Communication channels](https://docs.sboxr.com/view-issues/data-leakage-issues/all-data-leak)
* [All Data leaked via Referrer headers](https://docs.sboxr.com/view-issues/data-leakage-issues/all-referrer-data-leak)
