Why is Azure Sentinel so expensive?

I understand that Azure Sentinel is a cloud-based Security Information and Event Management (SIEM) tool offered by Microsoft Azure. However, I must ask, why is it considered so expensive compared to other similar solutions in the market? Are there specific features or capabilities that justify its higher price tag? Or is it due to the fact that it's a Microsoft product and therefore comes with an inherent premium? Could you please elaborate on the factors that contribute to the cost of Azure Sentinel and how it compares to its competitors?
