Upcoming Changes to Fusion in Azure Sentinel

The API to enable and disable Fusion in Azure Sentinel is going to be deprecated. We are making it easier to configure with an option in the UI, and it will be turned ON by default.  

Fusion uses graph-powered machine learning algorithms to correlate between millions of lower fidelity anomalous activities from different products such as Azure AD Identity Protection, and Microsoft Cloud App Security, to combine them into a manageable number of interesting security incidents.
