Are Software Defined Perimeters (SDP) in your Future?

Increasingly, we are seeing solutions emerge to address advanced threats that have penetrated the internal network (even internal threats) – most solutions focus on micro-segmentation,  network behavior analysis or multi-domain analytics.  I continue to have clients that are working to perform internal network and cloud-based  segmentation of their networks for security purposes. There are many ways to perform this segmentation, most of which focus on following workloads through some form of API integration with the client’s network hardware or workload management capability, moving towards SDN fabrics or deploying additional hardware firewalls.

One method that seems interesting (at least to me) is endpoint software that helps define what some are calling a “software defined perimeter” to reduce the deployment friction involved with complex integration or orchestration. SDP is often deployed as an agent technology that basically creates a no-trust network stack. Meaning, before packets are allowed to come into and be processed by the endpoint, an authentication step and encryption is performed. One interesting concept related to the endpoint to create dynamic trust was a DARPA project called Introduction Based Routing (IBR) (see

An SDP working group has been established at the Cloud Security Alliance (see The software defined perimeter (SDP) appears to be a very practical technology. SDP has the potential to be quite disruptive to traditional network technologies with positive implications for both enterprise networks and cloud deployments of the future.

If Gartner clients are interested in talking about this concept, feel free to ask for an inquiry.
