i can't block tiktok app

I can. Let me explain how i accomplished this.

1. define a new Catergory (Web -> Categories)

2. Add the above Category to your default policy (Web -> Policies)

Make sure this is the policy tour user will hit to block TikTok (e.g. mobile phone user group) 

3. Define a URL Group (Web -> URL groups)

4. Create a SSL/TLS inspection rule

5. Place the this rule in the right order (in my case it is the second SSL/TLS rule, right below the default Exclusion rule)

6. This is my result

Thanks for your answer Peter but first action doesn't work and i can't find SSL/TLS rule in my Sophos XG86 menu.

What version XG do you have installed? My instruction was based on XG v18.
And when you say "first action doesn't work", what do you mean? Couldn't you define/create a new Category?

im using sophos xg86, firmware SFOS 17.5.10 MR-10.

first action was new category and doesn't work.

Ok, since you're on XG v17:
Try this, just tested it and still works:

1. Make 4 FQDN host (Hosts and services -> FQDN host)

2. add thes 4 FQDN host to a FQDN groep, like this:

3. create a new FW rule (make sure it's high enough in the list with rules)

Let me know how this works out for you.

nothing has changed

Hi,

you need the tiktok firewall rule at the top of the firewall rule list not at the bottom.
