89% of the questioned have smartphones or tablets connected to their corporate networks but "Apple iOS is the most common mobile platform used to connect in corporate environments". Cupertino's mobile platform accounts for 30% of the devices connected, followed by BlackBerry with its 29% and Android's 21%. The Windows Mobile / Windows Phone combo still accounts for 18% of the total connected devices.
71% of the IT professionals consider that the addition of mobile devices on the corporate networks contributed to increased security incidents. However, Google's Android is regarded the least secure among the platforms. It is "considered to introduce the greatest security risks", and the answer came from 43% of those asked.
Google is continuously working on improving the security of Android in order to suit the needs of businesses. There's even a Security Enhanced version of the platform, released by the NSA, that aims at solving some of the problems related to security. However, the corporate world still thinks it is less secure than Apple's iOS (which is also less secure than RIM's BlackBerry OS).
