Worldwide global enterprise network and data security market is expected to cross $10bn by 2016, according to a report by ABI Research.

The market includes secure routers, unified threat management (UTM) appliances, firewalls, virtual private networks (VPN), intrusion detection/prevention systems (IDS/IPS), and network access control (NAC).

The report revealed that in 2010 the global enterprise network and data security market has showed resilience and spending recovery by registering 11% growth to reach $6bn.

The research firm said the enterprise security needs have intensified due to a growing diversity of threats but many of the them result from changes in enterprise information systems and access technologies.

The changes in enterprise information systems and access technologies include: increasing complexity of enterprise networks; greater use of cloud services; and more endpoints such as smartphones and media tablets connecting to enterprise networks.

It also includes connections by business users to consumer cloud services and applications such as social networking sites, particularly via mobile devices.

The report also said the small and medium-sized businesses (SMBs), which have limited IT resources and budgets, share similar security concerns as large enterprises do, and face comparable threat levels.

ABI Research senior analyst Subha Rama said vendors were responding to the market’s needs through portfolio expansion, and by offering multiple delivery models.

"Vendors are offering software blades and cloud-based security services in order to bring down security deployment costs," Rama said.

ABI Reseach practice director Dan Shey said convergence of communications and the growing use of social networking and smart devices were diversifying the environments containing potential threats.
