These are vendors that work with Google and are not listed under the TCF vendor list. If you work with Google Ad Manager you may want to review this list and enable the vendors that you are working with through Google Ad Manager, Admob, and Adsense. By default, all vendors are selected. For more information, see Ad Technology Providers.
On this screen, you can select the additional vendors you want to include in your ad request within Google AdManager. You can simply check or uncheck the vendors in the list. Note that the Google vendors are only used if the Enable Google Vendors checkbox is selected in the Privacy Sites configuration.
