REDWOOD CITY, Calif. – December 21, 2015 – In a recently published report, Dell’Oro Group, the trusted source for market information about the telecommunications, networks, and data center IT industries, predicts sales for the Virtual Network Security Appliance (NSA) market to accelerate in 2016. Cloud Service Providers are expected to be a major contributor to growth as they sell virtual appliances.

“The Cloud’s pay-as-you-grow pricing and on-demand provisioning allow companies to purchase only what they need, thus reducing up-front costs and ensuring efficiency,” said Casey Quillin, Director at Dell’Oro Group. “We expect customers’ comfort and confidence in the use of software security solutions to increase as several advantages offered by virtual NSA, including greater flexibility and novel security solutions that can monitor new vulnerabilities, will drive significant market growth. Looking forward, we forecast 2016 virtual NSA revenue will increase more than 60 percent over 2015 levels,” Quillin stated.

During 2015, several vendors saw very strong growth in virtual network security appliance sales, such as Barracuda Networks, Cisco, Fortinet, Juniper and Palo Alto Networks.
