SD-SASE
SD-WAN and SD-SASE are both based on the need for secure network communications. SD-WAN is an existing technology. SD-SASE is redundant nomenclature, as SASE solutions are expected to be SD. The reason for a SD-SASE chapter is to underscore the SD nature of future solutions. SASE is inherently SD on a per-service basis. Integrating SD-WAN with SASE leveraging SD tools and methodologies is the commonsense approach for the near future at least.
The simplistic view is that SD-WAN takes the place of the router at the edge of each network and then connects to other SD-WAN endpoints to securely forward traffic to where the necessary services exist. SASE industry standards incorporate SD-WAN into SASE services as a potential endpoint for secure communications to a physical or logical location.
Moving on to a security perspective, SD-WAN security mechanisms can securely interact with SASE services to increase the overall security posture of an organization. The ZTF and AI-based...
