The Next Frontier In Security
Cloud access security brokers provides visibility into general cloud application usage, data protection and governance for enterprise-sanctioned cloud applications, Gartner said. They deliver capabilities that are generally not available in other security controls such as web application firewalls (WAFs), secure web gateways (SWGs), and enterprise firewalls.
Hundreds of millions of dollars fueled the intial growth of the CASB market, according to Gartner. The market has matured in recent years with eight of the 14 CASB startups formed since 2011 having been acquired, allowing this technology to become a piece of a bigger vendors' portfolio.
Less than 10 percent of large enterprises use a CASB today to govern cloud services, according to Gartner. But by 2020, that figure is expected to hit 60 percent.
