Cloud apps should be as flexible and easy to access as possible, ideally from any location with internet access and from any device. However, it is precisely this ease of cloud access that often makes it easy for unauthorized third parties to access cloud data and misuse cloud apps. Cloud access security brokers ensure, among other things, that network traffic between on-site devices and the cloud provider only takes place in accordance with the organization’s predefined rules. They are also useful because they provide insight into the use of cloud applications across multiple cloud platforms, allowing unwanted use to be detected.
