Symantec also recently came up with a all 3G and Wi-Fi outbound Web and email traffic on the iPad through a virtual private network and detection server. The traffic is monitored and inspected using keywords and other detection technologies.

While these solutions sound interesting, CIOs really want Apple to bake some protections into iOS--and it did. With iOS 5, IT can turn off email forwarding so that corporate email cannot be forwarded through a personal account, MobileIron says. IT can also prevent apps from sending email.

"IT can now mandate that all email utilizes S/MIME, providing greater security and ensuring message integrity," wrote MobileIron, in an email to customers on how iOS will impact them.

When asked about data loss prevention on the iPhone or iPad, many CIOs will say that they can remotely wipe devices. While this is true, a data kill switch is a last resort. "By the time you wipe, you're way over the edge," says Aaron Freimark, IT director at Tekserve, a services firm helping Fortune 1000 companies adopt the iPad.
