kununu.com widget in Ghostery scope?

Edit Subject

kununu.com is a rate-your-employer type service aimed at german speaking audiences (I assume it is similar to glassdoor.com).
I have found the widget on the page xing.com (which is the mostly german version of linkedin.com), which is a 3rd party integration based on the domain, however the company is owned by Xing.
I assume the widget is used on other pages, which would definitely be 3rd pary.

the widget url is https://xing.kununu.com/widget/iframe...? and this shows up on https://www.xing.com/ after login.
