Jhonny_Smith_555  Thank you for the question and we will try to make this clearer in our documentation and messaging. You are correct that Sentinel and Exposure Management both integrate and unify information. Sentinel as part of our Defender XDR solution unifies usage and activity data while Exposure Managment brings together information about assets, their configuration and relationships.  
 Yusuf_Buhari  touched on the main difference is about use cases provided to you. Sentinel is used in Incident management to respond reactively to different threats such as breach and be able to analyze the anomalous activity to disrupt ongoing attacks and recover. Exposure Mangement is used to assess your internal and external attack surface to predict attack paths so you can proactively stay ahead of threats.
