The increase in virtualized and cloud networks is boosting demand for cloud based security, because data and applications are now more portable and distributed across a wide variety of networks. This means that security applications need to live as software in the cloud, rather than as dedicated hardware appliances protecting specific points of the network.
Demand is rising for cloud based, SAAS security solutions and the market is growing rapidly. These services can be provided as single features or as part of a larger, integrated SaaS package. Most current security systems possess outdated technology that relies on human monitoring which opens the opportunity door for more automated versions in the cloud. These security tools are also being integrated with software-defined networking (SDN) SDN to delivery a network that can use real-time analytics and monitoring to protect against emerging threats.
The entire managed security services saw 10-percent growth in 2014, up to $15.8 billion, with cloud-based offerings making up 46 percent ($7.2 billion) of that amount. That equates to a 13.5 percent growth in the cloud-based market from 2013 when it was worth $6.3 billion. The experts at IHS/Infonetics predict that cloud-based security will pass traditional Customer Provided Equipment (CPE)-based security services by 2018.
Pricing is another one of the main benefits of cloud based security, through usage-based pricing. This model dictates that there will be savings in the original investment, as well as funding for later maintenance of the system. With software continually being developed, you will not have to replace large and pricey pieces of equipment.
Pursuing a cloud-based security model does have challenges. In order to deliver comprehensive protection, security must be written into the architecture of a network. There are also a wide-range of security needs, which all require different applications and needs. In addition, the move to cloud-based applications poses its own threats.
The three most pressing cloud issues for businesses remain email security, web security and identity and access management. Throw in bring your own device (BYOD) trend from employees moving around within their company, Distributed Denial of Service (DDoS) attacks, and advanced threats, and many corporate IT managers are finding the need for a multi-faceted approach to security.
One of the largest challenges of implementing cloud-based security is the need to maintain consistent control and visibility across the different domains. With many existing networks, there is a combination of public and private (and even hybrid) cloud-based services, which makes the integration of security services and strategy a big task.
