CEF Context Broker is an API that can integrate data from multiple systems, creating a holistic view of information.

By providing the layer that describes each type of data, the Context Broker makes it possible to create an interface that makes it easy for anyone to view and interpret big data. Using the Context Broker, organisations can monitor their metrics in real time through live updates. You can share the context information you choose with third parties, enabling process improvements and innovation across the whole data value chain.
