Why Software-Defined Security Can Strengthen Branch Office Weak Links

By Chris Preimesberger  |  Posted 2016-08-12

Branch-office networks are proving to be a weak security link in many enterprises. In the 2013 Gartner Research report, "Bring Branch Office Network Security Up to the Enterprise Standard," analyst Jeremy D'Hoinne wrote that "30 percent of advanced targeted threats—up from less than 5 percent today—will specifically target branch offices as an entry point." While the attack landscape and threat vectors have evolved since that report was published, branch security architectures for the most part have not. Point security appliances such as next-generation firewalls (NGFWs), unified threat management (UTM) devices and software overlays in branch routers still dominate when it comes to protecting branch perimeter security; however, recent advancements in network functions virtualization (NFV) are enabling the same security features found in NGFWs and UTMs to be served via software as virtualized network functions. In this eWEEK slide show based on industry information from Versa Networks, Gartner Research and other resources, we look at why software-defined security is poised to disrupt proprietary security appliance makers.
