The virtual security appliances market will more than double to reach $1.17 billion from 2013 to 2018, said Infonetics Research.
The main growth drivers will be the increasing demand from enterprises, data centers, and telecom carriers.
Infonetics Research said the growth of SDN- and NFV-compatible security solutions is expected to drive consolidation in the virtual appliance vendor landscape, which is crowded with a mix of established security players, hypervisor vendors, and specialist vendors.
The revenue for data center security appliances to grow to $2.7 billion by 2018, said Infonetics.
Market share for data center security appliances fairly closely mirrors overall market share for security solutions, with Check Point, Cisco, Fortinet, Juniper, and McAfee in the top tier.
Enterprises and telecom service providers are upgrading data centers to support huge increases in traffic and handle the massive waves of attacks they face every day.
“We foresee a growth spike in virtual appliance revenue starting in 2016 due to the deployment of the next generation of network infrastructure using software-defined networking (SDN) and network functions virtualization (NFV) over the next year and a half,” said Jeff Wilson, principal analyst for security at Infonetics Research.
