In order to be able to block the Onavo application you need to to the followings:

1- Install the application on an IPAD. 
2- Set up proxy to the web filter on the IPAD. 
3- Open settings > VPN 
4- From the list of the VPN connections selected "Onavo" and opened the "!" sign which open the Onavo VPN configuration. 
5- According to your location , it shows "vpn-<your city>.v.onavo.com" and server IP <x.x.x.x> 
6- Blocked the subnet for the server IP with the netmask of 255.255.255.0 under block accept > ip block / exempt page and this will block the servers which Onavo is using to send your traffic.
