Cloud Services are at the core of IT infrastructure fueling the digital strategy of enterprises today. A look at the statistics below highlights the rapid rate of adoption of cloud services:-
- The public cloud service market is expected to reach $206.2 billion in 2019 worldwide. (source: Forbes)
- 83% of enterprise workloads will be in the cloud by 2020. (source: Forbes)
- 94% of enterprises already use a cloud service. (source: flexera)

Both cloud service providers and consumers are jointly responsible for security in the cloud. While the cloud service provider focuses on securing the data in the cloud and enterprise on the premises, user behavior and shadow IT leaves in-transit data vulnerable. There is a gap to secure the data which flows to and fro, from enterprise and the cloud service provider environment. This gap is addressed by security tools collectively termed as Cloud Based Access Security Brokers which extend the cover of an organisation’s security policies, by acting as a proxy between cloud apps and users.
What is CASB?
The term Cloud based access security broker (CASB) was coined by Gartner in 2012. In simple terms CASB represent an emerging market of products and services that provide cloud security solutions between cloud solution providers and enterprise on premise security policy perimeters. Gartner defines CASB as ‘on- premise’ or ‘cloud-based’ security policy enforcement points, placed between cloud service consumers and cloud service providers to combine and interject enterprise security policies as the cloud-based resources are accessed. CASBs consolidate multiple types of security policy enforcement. Example security policies include authentication, single sign-on, authorisation, credential mapping, device profiling, encryption, tokenisation, logging, alerting, malware detection/ prevention and so on’…Click here to read full article.
