As the number of businesses moving confidential or sensitive data to the cloud increases, so too does the need to ensure the security of that data. One option chosen by many businesses is to use a cloud access security broker (CASB.)
What Does a CASB Do?
CASBs serve an important role as a control point to ensure all of the enterprise’s cloud applications and storage are secure, across multiple cloud providers. They can control and monitor IT traffic, manage and protect the organization from threats, and provide cloud security.
More businesses are turning to software as a service (SaaS), infrastructure as a service (IaaS) and platform as a service (PaaS) tools. While these applications and services can provide enormous benefits when it comes to flexibility, expense control and collaboration, they also make security more of a challenge for IT teams.
CASBs work to set security policies and manage risk for all of the organization’s cloud services. In companies that have embraced CASBs, they are also responsible for enforcing a variety of security policies including authentication, single sign-on, device profiling, encryption, credential mapping, alerting and policies designed to detect and prevent malware.
Using a CASB also gives businesses the resources to monitor data traffic between the corporate network and various cloud platforms, helping them identify activity that may not be authorized so it can be stopped before accessing data stored in the cloud.
Different Business Reasons for Using CASB Providers
There are several different potential reasons businesses might choose to use a CASB vendor.
First, a company might choose a CASB for blocking and remediating malware, detect user anomalies and stop data infiltration activities for new employees.
Because CASBs have monitoring capabilities, some companies choose to engage them to monitor user activities and device usage, including monitoring social media or collaboration tools without blocking access to them. CASBs can also serve as gatekeepers, preventing data from going to unsanctioned cloud services.
Still other businesses engage CASB vendors to monitor and secure IT staff engaged in otherwise unmonitored “shadow IT” activities, looking for unauthorized cloud usage that could put the company at risk.
A Growing Market for CASB Vendors
As cloud-based applications and storage continue to grow, there will be an even bigger need for CASBs. As it is, the CASB market is growing at an annual growth rate of 17.6 percent; if projections hold true, the market will reach $7.5 billion by 2020.
