At VMWorld, this week VMWare showed of Horizon Mobile for iOS – an enterprise solution that separates business apps and content on an iOS device from a user’s personal apps, documents, and data. It’s an iOS version of a tool that VMWare previously demoed, but hasn’t yet shipped, for Android devices. While the name and the goal of Horizon mobile is essentially the same on both platforms, the company is taking a vastly different approach for iPhones and iPads.

Not only is the iOS approach different, it’s also nowhere near as revolutionary – other mobile enterprise companies have using similar approaches for a while and the one truly distinctive feature is one that Apple might not approve for distribution.

May is Mobile Management Month at Cult of Mac, where we will be profiling a different mobile management company every weekday. You can find all previous entries here  and read our Mobile Management manifesto here.

Although Good does provide device and app management, its primary focus is securing business data. To that end, the company effectively segregates all business information and documents on a device from a user’s personal content. To accomplish this Good’s iOS app delivers the same features as Apple’s Mail, Calendar, and Contacts apps – a move that ensures business messages event data are always secure. Good also includes a secure web browser and secure on-device document and data storage. The secure data store is sandboxed and can restrict users from copying data to unapproved apps as well as prevent such apps from accessing business documents or files.Good also provides a government agency solution that has been certified to meet various government and military standards for secure access including two-factor authentication.

Good leverages these technologies through a new solution called Good Dynamics that allows other companies, including mobile management vendor Boxtone who we profiled earlier in this series, to take advantage of Good’s secure data store. See our Good Dynamics coverage for more details.

Securing business data on employee-owned devices like the iPhone and iPad is one of the biggest challenges for IT departments when it comes to operating bring your own device (BYOD) programs. The mobile device management (MDM) approach taken by most companies is an excellent starting point because it aims to make devices themselves more secure. Unfortunately, it also tends to impose limits on what workers can do with an iPhone or iPad that they bought and paid for out of their own pockets.

Another approach to the challenge is to carve out a specific niche of secure storage on each employee-owned devices. Good Technology has always offered this mechanism for securing business emails and related technologies like shared contacts and calendars. This week, Good took that concept and made it available to iOS developers in a product called Good Dynamics.
