Cloud access security broker (CASB) software is used to provide a layer of protection and policy enforcement for employees accessing cloud-based software. CASB serves as a gateway through which companies can enforce their security requirements beyond on-premise and secure connections between employees and cloud service providers. Companies use CASB software to reduce risks related to cloud applications and network connections while simultaneously monitoring actions and behaviors.
CASB solutions are also used to identify abnormal behaviors from internal actors and then alert administrators of potential shadow IT and noncompliant behaviors. These tools typically monitor and record the actions taken by an individual using the CASB, who can leverage the data collected for behavioral analysis and reporting.
To qualify for inclusion in the Cloud Access Security Broker (CASB) category, a product must:
Secure connections between end users and cloud service providers
Enforce security policies beyond local networks and infrastructure
Protect data and connected devices from cloud-based threats and malware
