Chapter 2 IN THIS CHAPTER » Recognizing the limitations of MPLS » Getting innovative with SD-WAN » Addressing security threats with SWGs and SIGs » Introducing the secure access service edge (SASE) The Evolution of Networking and Security Solutions T he networking and security landscape is evolving from numerous, disparate point solutions to fully integrated, multifunction, cloud-delivered networking and security platforms. This shift is happening because businesses increas- ingly need the flexibility and power to deploy networking and security services how and where they choose. They need to control and secure Internet access, manage the use of cloud applications, and provide protection for roaming users while reducing strain on resources and eliminating the need for hardware. In this chapter, you'll learn how networking and security evolved from traditional wide area networks (WAN) to software-defined WAN (SD-WAN) and from secure web gateways (SWGs) to secure Internet gateways (SIGs). There is also information about the new, combined concept of the secure access service edge (SASE).
