Description
Throughout ongoing operating system development, Windows Phone has a process of MOS updates to add new features including improved enterprise and security capabilities as well as fixes to issues discovered after its initial release. These releases are termed General Distribution Releases (GDR). In working with DoD and our enterprise customers worldwide, requirements and issues were discovered that resulted in necessary changes to the Windows Phone MOS. One of those changes in the General Distribution Release 2 (GDR2) provides the capability needed to implement the VPN process required by the DoD to ensure that personal cloud services are blocked from use by the end user, and is the key to success for all associated requirements.
