This plugin can be used to filter incoming requests (from the SDKs) that match criteria you define.

You can create high level filtering rules such as ignoring all data coming from a certain country or IP address. It is also possible to filter data on session or custom event level granularity both with optional segmentation criteria, such as ignore all "Contact" events if it has segmentation property A equals to B or ignore all sessions originating from application version 0.9.
