Hi,

Is that possible to allow single youtube video and block all other videos and single word on firepower?

Thanks

Only if you have an SSL decrypt policy that's decrypting all of the YouTube sessions and thus able to go deep into the URL to filter out just the allowed videos.

+5 Marvin.

On a side note, practically its not possible to do this because youtube
hosts the videos on CDN servers which means that the URL for the same video
won't be fixed depending the datacenter where the video is served from and
many other factors which decides the selection process from CDN. The same
concept applies to facebook videos, whatsapp videos, etc. It might work for
some users but not others and later you might find its working for all or
not working for all, etc.

The introduction of CDN and content delivery makes its very difficult for
URL Proxys to track and filter.
