Cloud Access Security Broker
Cloud Access Security Broker (CASB) is software or hardware that sits between users and their cloud service to enforce security policies as they access cloud-based resources. Used to protect against cloud security risks, comply with data privacy regulations, and enforce corporate security policies. CASB controls and monitors access to cloud assets, usually SaaS solutions. CASB solutions are traditionally thought of as a method to offer a single login to multiple cloud services or a way to add MFA (multifactor authentication) to those services that don’t natively support it.
