As people and organizations adopt cloud services, Cloud Access Security Brokers (CASBs) have become a must-have for any information security team. CASBs provide critical capabilities such as governing access and activities in sanctioned and unsanctioned cloud services, securing sensitive data and preventing its loss, and protecting against internal and external threats. In short, CASBs enable organizations to extend their information protection policies and programs from their on-premises infrastructure and applications to the cloud. For organizations that are considering deploying CASB, it’s useful to consider the specific use cases they’re likely to address within these broad topic areas as they inform functional and architectural requirements.
