The OTT device ID blocklist provides additional defense mechanisms that are specifically optimized for OTT inventory. In order to achieve that, there is a need for various optimizations in the way the OTT signals from various sources are analyzed. For example, since OTT still generate lower volumes than regular mobile traffic, special segmentation is required in order to create OTT baselines for an OTT deviceID block list inclusion. Similarly, the time horizon that the OTT signals as well as the statistical significance thresholds used are optimized to fit better OTT.

Proxy Traffic
The proxy traffic included in the OTT device ID blocklist is the one that corresponds to fake SSAI, or in general, fraudulent proxy traffic. In order to achieve that, Pixalate has implemented a proprietary framework to detect fake SSAI proxies and only the devices associated with this activity is added to the blocklist.
IVT Types
The IVT types included are all the IVT types that one can see in the Pixalate’s dashboard, except the ones that can be triggered due to integration issues such as “duplicateImpressions” and “duplicateClicks”.
The blocklist contains the following additional categorization:
NOTE: The IVT type below that is not part of the Pixalate’s existing production dashboard will be added in the near future.
