Feature Request: Telegram

Could the category Chat and instant messaging be listed and have Telegram and other apps listed under the SDWAN>Firewall subsection? Or at least add it to the social web category. This app needs to be blocked as it exposes students to adult content.

It's a little old but maybe it can help you.



I am not a Cisco Meraki employee. My suggestions are based on documentation of Meraki best practices and day-to-day experience.

Please, if this post was useful, leave your kudos and mark it as solved.

This is great. That link will help me in the future.

Tik Tok also needs to be added to the social web category too.

I would very much recommend against attempting to block instant messaging outright, for two reasons.


1) Telegram by itself does not expose students to adult content any more than Whatsapp, Discord, Facebook Messenger, or any other instant messaging platform. 


2) In my experience, when you get heavy-handed with network restrictions in this manner you will not actually prevent the behavior you are trying to stop, you will instead push clients to download sketchy alternative apps that are less safe/less moderated or to VPNs, or they will just switch to cellular data.


It is my belief in general that you are much better off having the apps allowed but categorizing the traffic with NBAR and having some record that the clients were using the app if an incident occurs (in case they delete the app/wipe their phone, etc to try to pretend they weren't part of some incident)

Blocking instant messaging is a bit much but it would help to block some apps and the adult content traffic. Could you please explain more about NBAR and how to implement it on the Meraki firewalls?
