Twitter not blocked because of categorization order

Hello,
I had setup time based policy to block social networking, but UTM is not blocking Twitter although it is detecting "Twitter" as the application.
When testing the url "twimg.com" through the policy help desk in the UTM, it shows the url category as "Content Server" and not "Social networking". 
I checked the Trusted Source Smart Filter XL database, Twitter is categorized as "Content Server" in the 1st position and "Social networking" in the 3rd position.

I think something is not coherent here and could be fixed :
UTM should do some correlation between "Twitter" as a detected application and "Social networking" as a category,
or,
UTM should check the url against all the categories listed in the Smart Filter XL database and apply the most restrictive schema.
PS: I raised a reassessment ticket to Trusted Source and got a negative feedback.

  • Both CFF and SXL use the same database, SXL just uses the cheaper (free?) access to only the first categorization.

  • Thank you for the info.
    I don't know why is twitter categorized as "Wiki" instead of "Social networking" but I understand it is not the UTM issue. I ended up blocking it explicitly.
