These products filter malware from user initiated Web traffic with processes such as URL filtering, malicious code detection and filtering, Web-application controls and data loss prevention. Right now, Gartner contends that 87% of the products in this market were sold in on-premise bundles in 2011, with the remaining sold as a service. The consultancy estimates the SaaS segment rose to 35% last year.
Company name: Cisco
Product Names: IronPort S-Series appliances and ScanSafe service
Why we are watching: Cisco bought IronPort in 2007 and ScanSafe in 2009 and has been steadily building links between the appliance and the service across its networking and security gear so that both are easier to implement in Cisco-focuses enterprises.
Company name: BlueCoat
Product Name: Proxy SG and BlueCoat Cloud Service
Why we are watching: The on-premises Proxy SG product is well-tested in large enterprise environments for scalability and performance and the list of protocols, authentication options, back-end databases and antivirus platforms it supports are long across the board. The service option is based on the ProxySG boxes.
Company name: Websense
Product Name: Security Gateway and Security Gateway Anywhere
Why we are watching: The company has a focus on data leak prevention as its main differentiator and it's got an acclaimed Triton management console that helps enterprises manage both appliances and the service (which has the same name as the appliance with the addition of "Anywhere") from the same pane of glass should they want to run with a hybrid security strategy.
Company name: Zscaler
Product Name: Zscaler Web Security
Why we are watching: Zscaler is a fast growing start-up that offers its product only as a service. Gartner has said this is the fastest growing company in this market segment driven by its very strong reporting capabilities, client redirection functions, granular security controls, and flexible, policy-based controls for social media applications.
This segment of cloud security homes in on locking down both the hypervisor that enables virtualization in the first place and seeks to thwart ill-intentioned communications between the virtual machines running on it.
