Cloud access security brokers -- or CASBs -- have been around for several years now, but they are gaining in prominence with the rise of cloud-based applications and the need to secure the growing activity in this space.

That explains why competition is booming in the CASB market, according to a recent Gartner report, and also why managed security service providers are now building CASB technology into the services they offer. The market leaders include pure-play companies such as Netskope, Skyhigh Networks and Bitglass, as well as traditional security vendors who have acquired CASB technology, including Cisco Systems Inc. (Nasdaq: CSCO), Palo Alto Networks Inc. and Symantec Corp. (Nasdaq: SYMC).

The diversity of software-as-a-service (SaaS) applications today is a boon to enterprise security, but many of these apps don't come with security analytics baked in. What CASB software does is provide both visibility into cloud-based applications and the security analytics needed to ensure those apps are being used properly and by the right parties, so corporate data and systems aren't put at risk.
