Software Defined Perimeter

The Software Defined Perimeter (SDP) is a new approach to security that mitigates network based attacks by dynamically creating perimeter networks anywhere in the world—including in a cloud, on the DMZ, and in the data center.

“SDP technology enables organizations to provide people centric, manageable, ubiquitous, secure and agile access to networked systems, services and applications. It does this by solving a core design flaw in the unsecure manner in which TCP/IP was developed.”
— Gartner
