Enterprises that have grown comfortable with Software as a Service (SaaS), Infrastructure as a Service (IaaS) and Platform as a Service (IaaS) are increasingly accepting of Network as a Service (NaaS). NaaS is a rapidly growing market. According to Market Research Future, NaaS is expected to become a US $126 billion market by 2022, sustaining an annual growth rate of 28.4 percent.
One of the key benefits of cloud-based networking is increased security for applications and data. Given that the traditional perimeter of on-premise networks has been decimated by mobile and cloud computing, NaaS builds a new perimeter in the cloud. Now it’s possible to unify all traffic – from data centers, branch locations, mobile users, and cloud platforms – in the cloud. This means an enterprise can set all its security policies in one place, and it can push traffic through cloud-based security functions such as next-generation firewall, secure web gateway, advanced threat protection, and so on.
