From a security perspective the Cloud has brought with some new challenges, and some new risks. It introduces a challenge for IT departments - do we accept the inevitable and enable Cloud applications to be used, or do we take a strict stance and try to prevent their use?
Enter the Cloud Access Security Broker, or CASB for short, a security platform that enables both. Gartner estimates that by 2016, 25% of enterprises will be securing access to cloud-based services using Cloud Access Security Brokers (CASB), reducing the cost of securing access by up to 30%.
CASB platforms exist to provide a visibility and control layer, either in the Cloud or on premise, over both sanctioned and unsanctioned Cloud based applications. They give visibility into the Cloud app's that are being used and the data being stored in them, as well as providing a platform for secure Cloud enablement, giving you the ability to enforce policy based control over what Cloud app's are in use, what data is stored in them and how that data is secured.
