There are a number of 'remote data wipe' applications available. Most only allow either a) a wipe of the entire phone, or b) the password to be changed remotely. As far as we know, there is no other option that allows policy control at the fine-grained levels we have created or creating physical boundaries (e.g., rooms) that define where data can be accessed. Commercial applications only allow control of 50 or so policies, which are typically centered around controlling the Android system settings. Our work goes much farther than that, allowing extremely fine grained control of many parts of Android beyond just system settings. Additionally, we are the only solution we know of that allows integration with secure data, such as contacts and email, while ensuring that the sensitive data remains in memory and no traces of that data remain on a device.  

Got any companies sniffing around yet to use this commercially?

We are working with various defense contractors and are planning to meet with Google Federal soon. 

Overall, how big of a concern do you think smartphone security is these days/going forward?

Smartphone security is a huge concern. These devices enable a faster, more efficient communication with the world, but as users are adding features to their smartphones (calendars, email, contacts, social network logins, bank applications) they are making that device more of a security risk if it is lost or stolen. As smartphones become more prevalent, we have been seeing digital attacks targeted at every major platform. Smartphones are incredibly useful as devices, but trading all personal security for that usefulness is not the choice that consumers should be forced into.
