The software-defined perimeter (SDP) is a cloud-based approach to secure access. SDP mediates the connection between users and internal applications, without placing users on the network. While the traditional security perimeter were designed to protect internal services from external threats, the widespread use of SaaS applications and IaaS extend the perimeter to the internet. The software defined perimeter enable organizations to deploy the perimeter in the cloud so it can protect assets anywhere they reside-inside the data center or in public or private clouds.
