Is Microsoft Sentinel a SIEM?

I'm curious about the capabilities of Microsoft Sentinel and its classification within the security monitoring landscape. Could you please clarify whether Microsoft Sentinel can be considered a Security Information and Event Management (SIEM) solution, and if so, how does it compare to other popular SIEM tools in terms of features, scalability, and integration capabilities? Additionally, are there any unique benefits or advantages that Microsoft Sentinel offers that set it apart from other SIEM solutions?
