The demand for software-defined wide area network (SD-WAN) technology is growing exponentially. A report predicted that this technology will become a $6 billion industry by 2020. SD-Wan can be up to 2.5 times less expensive than a traditional WAN due to lower savings generated by using secure edges. The thrust of the zero trust security approach is to stop trusting applications, users, networking devices or networks by default, and instead implement a regime of continuous verification. The zero trust model focuses on authenticating first and providing network security access second.”]
