+If <PlatformIdentifier name="send-default-pii" /> is set to `False`, the default scrubber implementation will run automatically and filter anything in the [`denylist`](TODO-neel) from [potentially sensitive interfaces](/platforms/python/data-collected/) in the event payload.

+```python
+import sentry_sdk

+    send_default_pii=False,
+    event_scrubber=EventScrubber(),  # this is set by default
+)

+You can also pass in a custom `denylist` to the `EventScrubber` class and filter additional fields that you want.
+
+```python
+from sentry_sdk.scrubber import EventScrubber, DEFAULT_DENYLIST
+
+# custom denylist
+denylist = DEFAULT_DENYLIST + ["my_sensitive_var"]

+sentry_sdk.init(

 This option can be used to supply a "server name." When provided, the name of the server is sent along and persisted in the event. For many integrations, the server name actually corresponds to the device hostname, even in situations where the machine is not actually a server.

 ## Scrubbing Data

+You can use the <PlatformIdentifier name="event-scrubber" /> configuration parameter to simplify removing sensitive data from your event payload.

+### `before_send`
+
 SDKs provide a <PlatformIdentifier name="before-send" /> hook, which is invoked before an error or message event is sent and can be used to modify event data to remove sensitive information. Some SDKs also provide a <PlatformIdentifier name="before-send-transaction" /> hook which does the same thing for transactions. We recommend using <PlatformIdentifier name="before-send" /> and <PlatformIdentifier name="before-send-transaction" /> in the SDKs to **scrub any data before it is sent**, to ensure that sensitive data never leaves the local environment.
