Gartner defines CASB as follows:
Cloud access security brokers (CASBs) are on-premises, 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. CASB consolidates multiple types of security policy enforcement. Example security policies include authentication, single sign-on, authorization, credential mapping, device profiling, encryption, tokenization, logging, alerting, malware detection/prevention, and so on.
How is CASB useful?
When a company uses cloud-based software, there are some risks involved, like not knowing how many unsanctioned applications are being used by employees without permission. This is called Shadow IT.
Cloud Access Security Broker (CASBs) solutions help companies manage these risks and make sure their data is secure. It can help a company see what applications are being used, control access to it, and protect the data in case of any threats or leaks. This is done through CASB policies.
Basically, CASB is like your security guard for a company’s cloud-based software.
