Steve Damadeo, IT Operations Manager Festo Corp., a producer of pneumatic and electric drive technology, said his first approach with employees who want to use personal technology at work is to educate them. "We try to spend a lot of time talking to employees about why it's important to make sure when you're inside our environment that you're using corporate secure resources," he said.

Festo hasn't used wireless jamming or blocking technology because it is trying to keep wireless communications as open as possible.

Like many enterprises, Festo has multiple secure wireless networks, three of which its employees can access. The company's primary wireless network is used for access to internal systems and data via authorized mobile devices; users of it are managed via custom-built mobile device management software.

A second network is offered to employees who want connectivity to the World Wide Web via their own mobile devices; that one allows access through a VPN. "We've not enabled full BYOD within the company, so at this point we're able to provide VPN capabilities to them," Damadeo said.

The third wireless network is for guests, and it is made available on a rotating encryption/key basis for visitors.
