In addition, the architecture of the Good VPN is unlikely to drain the battery of a mobile phone, a problem with some other mobile VPN products, Ryan said.

The updated platform also includes Good Mobile Control, a device management tool that is Web based for easier access by IT administrators. A manager can use the tool to manage mobile phones, remotely wiping devices that might be lost or stolen, monitoring device status and examining features that devices have.

Good also announced that administrators can now manage the iPhone through the control tool. That could please IT administrators who have struggled to manage iPhones used by workers, Brackbill said. Good would like to add iPhone support in its other offerings and hopes to be able to in the future but for now the iPhone software developer kit is just too limited, he said.

The new capabilities make the Good platform more useful within an enterprise. "It's moving them in the direction of adding more to the platform beyond just e-mail. It's more full service," said Ryan. "It starts to become a platform that either they can develop more applications beyond e-mail or they can partner with other people to mobilize existing enterprise apps."
