Hi Ahmed, Google made a change a few months ago to the way they implement YouTube Safety Mode, which affects our ability to accurately identify this traffic with our youtube-safety-mode App-ID signature. As such, the App-ID for YouTube Safety Mode will likely not show up anymore. If you would like to enforce YouTube Safety Mode, you can do this via a URL filtering feature, "SafeSearch Enforcement". When enabled, any Google, Yahoo or Bing web searches will be checked to make sure that the strictest Safe Search setting is enabled, and this applies to YouTube Safety Mode as well. If the settings are correct, the search is allowed. Otherwise, a block page is displayed, with instructions on how to correctly fix their settings. Once this has been done, all subsequent searches will go through. In order to ensure that YouTube Safety Mode is covered, please be sure to install content version 422 or later. Thanks, Doris
