The Irrelevance of the Network Perimeter

• Relying on firewalls and other technologies to partition a network into an internal private network and an external public network is no longer adequate to protect an organization using on-premises and Internet hosted services.
• Microsoft’s traditional client management technologies for enterprises were designed primarily for endpoints such as Windows PCs, primarily on an internal network.
• Microsoft 365 can secure and enforce compliance of cloud services and devices outside the corporate network but requires premium licensing.

Organizations have to manage and secure more and more cloud or hosted services and devices that are personally owned, unmanaged, used off-premises, or not running the Windows OS. That means organizations can no longer focus on managed Windows PCs inside a traditional internal network perimeter. Microsoft has built a set of online services to address the problem, but any solution requires licensing multiple high-end security and compliance services.
