REDWOOD CITY, Calif. – January 21, 2015 –According to a recent report by Dell’Oro Group, the trusted source for information about the networking and telecommunications industries, the Network Security Appliance (NSA) market is forecast to exceed $11 billion in 2019, driven by strong virtual appliance revenue growth.

“Virtual appliances can provide greater flexibility, allowing for a more “customized” security approach through software configuration and scripting. In addition, co-operation between virtualization and security solution vendors has increased considerably, resulting in virtual security appliances that are directly integrated with hypervisors, such as VMware and Hyper-V,” said Casey Quillin, Director of Data Center Appliance Market Research at Dell’Oro Group. “Looking to the future, virtual security appliances will be an attractive option for software-defined networking (SDN) and network functions virtualization (NFV) initiatives, that promise to enable network programmability and the automation of hardware configurations,” Quillin explained.

The Dell’Oro Group Data Center Appliance 5-Year Forecast Report includes manufacturers’ revenue, unit shipments, and average selling price projections for NSA, Application Delivery Controller and WAN Optimization Appliance markets. The report also includes NSA segmentation based on threat type – Content Security, Firewall – Enterprise, Firewall – SMB, IDS and IPS, and VPN and SSL.
