Think of cloud access security brokers (CASBs) as central data authentication and encryption hubs for everything your enterprise uses, both cloud and on-premises and accessed by all endpoints, including private smartphones and tablets. Before the CASB era, enterprise security managers had no visibility into how all their data was protected. As bring-your-own device (BYOD) and unmanaged devices became popular, data could be at risk when accessed from someone’s phone or tablet.
