The application, called activEcho, is designed to allow employees to securely share and sync files across devices such as an iPad, iPhone and Windows laptops, said Anders Lofgren, vice president of product marketing at GroupLogic in Arlington, Virginia, which is known for its tools to integrate Macs into Windows environments.

Unlike Dropbox, activEcho doesn't store any files on GroupLogic's servers. The software runs on a server controlled by the customer, or, if a company chooses, a service such as Amazon Web Services, Lofgren said. GroupLogic doesn't sell any storage for activEcho.

Of the 50 companies that have been testing activEcho for the last three months, all but one ran the software on their own infrastructure behind a firewall, Lofgren said. Companies tend to want to be in control over their data, he said.

"Especially in regulated industries, they want to be in control because they have certain standards they have to meet," Lofgren said.

GroupLogic has put several features into activEcho that should appeal to administrators looking to wean their employees off Dropbox.
