In comparison, if the Good-based units are lost or stolen, only the corporate container is wiped.
It's not surprising, then, that some employees are concerned about turning their personal smartphones over to "Big Brother." The Good alternative, Perkins says, is more palatable for users who want access to just the basics: email, calendar and a secure browser.
This is a newer, more granular approach in which each app is enclosed in its own encrypted policy wrapper, or container. This allows administrators to tailor policies to each app. Small vendors with proprietary approaches dominate the market, including Mocana, Bitzer Mobile, OpenPeak and Nukona (recently acquired by Symantec).
For its part, RIM is working on adding this capability to its BlackBerry Mobile Fusion MDM software, possibly as soon as May 2013. (Mobile Fusion runs on Android and iPhone devices as well as on the BlackBerry.) Peter Devenyi, senior vice president of enterprise software, says RIM's offering will be "a containerized solution where one can wrap an application without the need to modify source code so you can run it as a corporate application and manage it as a corporate asset."
"Using these tools you can put together a pretty complete, fully wrapped productivity suite that's encrypted and controllable," says Jeff Fugitt, vice president of marketing at mobile integrator Vox Mobile. So far, however, the customer base for the technology is relatively small.
Forrester analyst Christian Kane describes app wrapping as an "application-level VPN" that lets administrators set policies to determine what the app can interact with on the user's device or on the Web, and what access the app has to back-end resources. It also allows for remote wiping of the container, including the app and any associated data.
Application wrapping is not mature. Phil Redman, Gartner analyst
"Application wrapping is not mature," says Gartner's Redman, and the existence of competing architectures in this nascent market is holding back growth. But the adoption of app wrapping for enterprise and third-party apps will increase, he says, as the technology is eventually integrated into the larger and more established MDM platforms.
