Mobility & Cloud have irreversibly changed every aspect of enterprise IT security. A user on their smartphone accessing Microsoft Office 365, has no part of that communication controlled or even seen by the traditional enterprise DMZ & Perimeter model. The user, connected to a mobile network, and the application in the cloud makes traditional enterprise perimeter models ineffective
A new approach to the perimeter is required, one where the user themselves is the new perimeter and security can built around the user, no matter what device they use or application they access. A perimeter built on user identity, their device state and network locality where security services can be infused without impacting the native user experience.
