Puffin browser is an app which allows private browsing. This would allow a user to circumvent filtering, and so it may be desirable to block this.
Note: The Puffin Web Browser described is NOT Puffin Academy.
There are two main methods of blocking Puffin Browser:

Checking the SSL certificate
Blocking by the SSL certificate is more effective and reliable as it will hold, even if the IP addresses above are changed.
Puffin Web Browser uses HTTPS in network communication; using
http://cloudmosa.net as the common name in their SSL certificate.
In this case, add
http://cloudmosa.net to a custom category and block policy instead of the IP addresses detailed above.
