Whisper is a free messaging app by WhisperText LLC. It has both private chats as well as pseudo-anonymous local chat features.


Blocking Whisper

In order to prevent Whisper from functioning on your network it will be necessary to add the following domains to your blacklists:


As of Cipafilter version 8.4 and above, these domains are already included in the "Chat" blacklist category. 

Please note that this will only prevent access when the user device is connected to the organization network. There is no way to prevent use of the app over a mobile carrier's network.
