I read with some surprise the interview with Zscalers CEO, Jay Chaudry, in CRN where he stated that the network firewalls will go the way of the mainframe, that the network is just plumbing and that Zscaler proxy overlay architecture will replace it with its application switchboard. The proxy firewalls faded. I guess not.

Since the beginning of networks, the lynchpin of network security has been the firewall. The first network firewalls appeared in the late 1980s, and gained almost universal acceptance by the early 1990s. So what is a Firewall as a Service and why do you need it? What is FWaaS, and Why Do You Need It?

If you’re like many of the IT leaders we encounter, you’re likely facing a refresh on your firewall appliances or will face one soon enough. And while the standard practice was to exchange one firewall appliance for another, increasingly, enterprises seem to be replacing firewall appliances with firewall-as-a-service (FWaaS).
