So are these mobile devices locked down so they can not change dns? Great you might be able to setup the mobile device to use a specific dns that in turn would return a block page IP for fqdn you want to block say www.playboy.com or something
But what happens when any user with an IQ of say 70 or higher figures out that he can just change his dns to dhcp and not be filtered while at his house, starbucks, local inet cafe, etc.
I have to assume you can lock these devices down to prevent them from changing that? Another issue that comes to mind with mobile devices and locking dns to say opendns. What if they are at a location and need to resolve local zones for resources say www.localdomain.lan while at a customer/vendor site? Opendns is not going to be able to resolve non public based zones that are only served by the local dns to local clients.
Just some stuff to take into account - filtering devices that are outside your network can be a tough battle. One that many companies have decided not to fight. So while you can not surf porn while at the office on your smartphone - once you take it out of the network you can surf what you want, etc.
Yes this is added risk to be sure, but unless its company owned device and can be completely locked to prevent user tampering in such a way to not at same time restrict productivity or access while on some odd ball network it can be difficult.
