Nice video, just a bit shameful for a German company not to provide a German version.
Happy that you like the video. The people who contributed to the video put a lot of work into it, and they will love to hear it. I would not call it “shameful” that Greenbone uses the english language to care of all users, who are mostly non-german speakers. This is why this forum here uses english as lingua franca.
Anyway, I heard that a german version is planned too, but I do not know any target date for this.
