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. This is my take.

Every organization eventually needs to re-evaluate their existing firewall vendors. In these situations, network managers need to evaluate the state of their vendors firewall and the future viability of their security software and hardware. UTM appliances are no exception, with rules for each appliance requiring diligent maintenance.

About 10 years ago, a small startup, Palo Alto Networks, innovated the Next Generation Firewall (NGFW). Existing enterprise firewalls relied on the use of specific ports to apply application security rules. By application, I dont mean salesforce.com. Firewalls are complex entities.

Firewalls Evolve Over the Years Before the UTM, there was the basic firewall. All traffic passed through the firewall for basic inspection of security policies based on network information such as the type of protocol or the source/destination addresses. The same can be said on the application side.
